[0004] TECHNICAL BACKGROUND

[0005] In the supply and production of products multiple regulatory requirements need to be met, which differ depending on the product. To fulfil such regulatory requirements, data on such products may need to be exchanged between different participants involved in the production and use of such products. Such data may be exchanged in a secure and controlled manner within a decentral network connecting different participants involved in the production and / or recycling of the product. Owing to the transfer of highly standardized data packages within the decentral network, generation of such data packages is cumbersome in handling, especially for various supply chain participants. Hence, there is a need to simply generation of data packages, in particular for production input(s) used to produce the product, which can be exchanged via a decentral network while at the same time ensuring transfer of all data required for further processing, such as for generation of chemical product passports associated with the product.

[0085] Any disclosure, embodiments and examples described herein relate to the methods, the apparatuses, systems, the uses and computer elements lined out above and below. Advantageously, the benefits provided by any of the embodiments and examples equally apply to all other embodiments and examples.

[0086] Embodiments

[0087] In the following, embodiments of the present disclosure will be outlined by ways of embodiments and / or examples. It is to be understood that the present disclosure is not limited to said embodiments and / or examples.

[0088] To enable or improve the exchange of chemical product data associated with chemical product(s) used as input material to produce at least one battery, simple and efficient generation of such chemical product data is crucial. However, sharing of chemical product data within a decentral network is generally associated with the use of highly complex semantic model(s) or data model(s) to ensure uniform data set(s) containing all required data point(s). Such complex data model(s) are, however, associated with high cost for generation and maintenance. Hence, use of such complex data models makes the generation of chemical product data set(s) a complicated and tedious effort. Such effort may not be feasible for small supplier companies, hence posing a hurdle for sharing chemical product data associated with chemical product produced by such companies via the decentral network with downstream production stage(s) associated with the production of the battery.

[0089] By using a rule-based engine including rule(s) associated with the battery produced from such chemical product(s) as input material(s), in particular associated with data model(s) of the battery or a battery type the battery is associated with, it can be ensured that chemical product data point(s) required according to the data model, such as an aspect model, associated with the battery or battery type are contained in the chemical product data set, hence avoiding missing data point(s) during generation of a battery passport associated with the batteries using said data model. Since the rule(s) are derived from the data model of the battery or battery type, suppliers producing chemical product(s) used in the production of such battery do not necessarily have to use complex data models to generate the chemical product data set(s). Instead, they can use existing complex data model for batteries or battery types and generate the rule(s) based on such existing data models, hence avoiding costly and cumbersome generation of such models for their produced chemical products. This way, the data quality of battery passports generated based on the chemical product data sets may be improved, allowing to improve the processing of the battery, such as an end-of-life battery, and / or the production of product(s) produced from the battery based on the data included in the in battery passport.

[0090] By transforming the gathered chemical product data using such rule-based engine, aggregation of the gathered chemical product data into a given data structure, such as a tabular representation, can be achieved without the use of complex data models, hence facilitating simple generation and reliable sharing of chemical product data set(s) within the battery ecosystem via the decentral network. The chemical product data set(s) may be associated with authorization rule(s), hence avoiding unauthorized access to such data and ensuring secure sharing of such data via the decentral network. The chemical product data, such as the tabular representation, may be stored within a dedicated storage associated with the data owner of the chemical product data for consumption of such chemical product data by a decentral data consuming node associated with a data consumer under the control of the data owner. Hence, the chemical product data can be directly consumed based on identifier(s) associated with such chemical product data and endpoint(s) of decentral data providing node(s) associated with the dedicated storage without having to use any intermediary registries, such as decentral registries storing access elements pointing to 'data set(s) generated using highly defined data models. This way, the effort for sharing the generated chemical product data set(s) within the decentral network may be reduced, allowing more reliable sharing of such data set(s) and hence also a higher data quality of passports generated based on such data set(s).

[0091] By using rule template(s) including unstructured data associated with transformation operation(s), generation of one or more rule(s) may be facilitated using natural language, hence allowing simple and reliable generation of rule(s) based on natural language text, such as user input, contract clauses, etc. In addition, the rule template(s) may be predefined, hence allowing generation of chemical product data set(s) based on given rule template(s) and rule(s), resulting in a further simplification of the generation of the chemical product data set(s).

[0092] By enabling simple and efficient generation of chemical product data set(s), such chemical product data set(s) can be reliably shared within the decentral network by upstream production stages. Such sharing may enable more efficient production and / or recycling processes based on the shared chemical product data, for instance based on chemical product composition data included in the shared chemical product data. By using the decentral network, the generated chemical product data set(s) may be shared in a secure and controlled manner by avoiding access to such data set(s) by unauthorized decentral network participant(s), hence avoiding unwanted transparency on supply chains and / or chemical composition of the chemical products by third parties.

[0093] By using a rule-based engine operating on data point level, multiple data points level or whole data level, it may be ensured that the generated chemical product data set include(s) all chemical product data point(s) required by the data model associated with batteries or battery types. This ensures that battery passports associated with such batteries can be reliably generated from chemical product data gathered via the decentral network, without a risk that required data point(s) are missing, hence resulting in the battery passport having a low data quality. Since it may be required that batteries and / or products containing such batteries which sold to customers are associated with such battery passports, lack of generation of such battery passports due to missing chemical product data may result in increased storage times of batteries or products including such batteries and may negatively influence downstream participants of the ecosystem due to lack of battery and / or battery containing product supply. In addition, low data quality of the battery passports may negatively influence the production of products using the battery and / or the processing of end-of-life batteries based on the data included in the battery passports.

[0094] By validating the chemical product data set(s) generated in a simple and efficient way using a rule-based engine including rules associated with batteries produced using chemical product(s) associated with such data set(s) as production input(s), it can be ensured that the consumed chemical product data set(s) include the data point(s) required by the data model. This allows to avoid missing data points upon generation of battery passports associated with such batteries using the consumed chemical product data. Validation of consumed chemical product data sets by the consumer side ensures that the battery passport contains all data required by a data model used to generate such battery passport, hence allowing to reduce the complexity associated with the chemical product data set generation at the provider side by avoiding the use of complex ata models during generation of the chemical product data set(s) since this complexity is shifted to the consumer side. This may enable reliable sharing of chemical product data of chemical product(s) irrespective of the existence of data models for such chemical products since the rule(s) required to transform the gathered chemical product data may be readily derived or generated from the data model associated with batteries or battery types or from data models derived from the data models associated with the batteries or battery types.

The one or more rule(s) may hence not be derived or generated based on a data model associated with the produced chemical products. This may allow to avoid generation of complex data models for produced chemical products but may instead allow to use existing data models of batteries or battery types for generation of rule(s) to transform gathered chemical product data to chemical product data set(s).

[0110] The rule-based engine may operate on individual data point level, combination of data points or the whole gathered chemical product data.

This may ensure that chemical product data required by the semantic model is included in the gathered chemical product data, hence ensuring reliable and efficient generation of battery passports using such validated chemical product data.

[0112] The rule-based engine may operate on individual data point level, combination of data points or the whole gathered chemical product data. The operation of the rule-based engine may be defined by the one or more rule(s). Rule(s) associated with individual data point(s) may include one or more rule(s) defining condition(s) for individual data points present with the gathered chemical product data.

[0114] In an embodiment, the one or more databases are distributed databases, wherein at least one of the databases stores instance(s) of the chemical product data. A distributed database may be a collection of data stored at different sites of a computer network. Each site might expose a degree of autonomy, providing services for the execution of local applications, but also participating in the execution of a global application. For instance, a distributed data source may be a distributed database. A distributed database can be created by splitting and scattering the data of an existing database over different sites or by federating together multiple existing databases. Each data source may contain only a fragment of the data associated with the respective chemical product. This leads to a fragmentation of said data. Two common types of data fragmentation are horizontal fragmentation, wherein (possibly overlapping) subsets of data tuples are stored at different sites; and vertical fragmentation, wherein (possibly overlapping) subtuples of data tuples are stored at different sites. More generally, the data associated with the respective chemical product may be fragmented into a set of relations (tables of a relational database, distributed across multiple sites).

The sensor may correspond to the measuring device.

[0119] Recyclate content data and / or bio-based content data may comprise any data related to the recyclate content or the bio-based content used for providing or manufacturing the chemical product.

[0120] Emission data may comprise any data related to environmental footprint. The environmental footprint may refer to the chemical product and its associated environmental footprint. The environmental footprint may be chemical product specific. For instance, the environmental footprint may relate to the chemical product or additional chemical product-specific relations. Emission data may include data relating to the carbon footprint of the chemical product or a Product Carbon Footprint (PCF). Emission data may include data relating to greenhouse gas emissions e.g. released in production of the chemical product. Emission data may include data related to greenhouse gas emissions.

[0121] Emission data may include data related to greenhouse gas emissions of an entities or companies own operations (production, power plants and waste incineration). Scope 2 may comprise emissions from energy production which is sourced externally. Scope 3 may comprise all other emissions along the value chain. Specifically, this may include the greenhouse gas emissions of raw materials obtained from suppliers. Product Carbon Footprint (PCF) may sum up greenhouse gas emissions and removals from the consecutive and interlinked process steps related to a particular chemical product. Cradle-to-gate PCF may sum up greenhouse gas emissions based on selected process steps: e.g. from the extraction of resources up to the factory gate where the chemical product leaves the company. Such PCFs may be called partial PCFs. In order to achieve such summation, each company providing any products may provide the scope 1 and scope 2 contributions to the PCF for each of its products..

Production data may include monitoring and / or control data associated with the production of the chemical product.

[0123] In an embodiment, the rule-based engine operates on individual data points present within at least part of the gathered chemical product data, multiple data points present within at least part of the gathered chemical product data or the whole gathered chemical product data. The rule-based engine may be configured to transform gathered chemical product data based on one or more included rule(s). The rule- based engine may apply one or more rule(s) to individual data point(s), multiple data point(s) and / or the whole data set to generate the chemical product data set(s). If the rule-based engine determines that individual data point(s), multiple data point(s) and / or the whole data matches one or more condition(s) in the rule(s), such individual data point(s), multiple data point(s) or the whole data may be included in the generated chemical product data set.

[0124] In an embodiment, the one or more rule(s) are generated from a rule template including unstructured data associated with instructions related to transformation operation(s). The instructions may signify the transformation operation(s). The instruction(s) may relate to the transformation operation(s). The transformation operation(s) may relate to aggregation chemical product data gathered from multiple data sources into a given data structure, filters to filter gathered chemical product data, attribute construction(s) to create or add new attributes to the gathered chemical product data and / or a trigger condition and a corresponding group of one more actions. The rule template may be used to generate executable logic that may be executed by the rule-based engine. Use of a rule template may facilitate generation of one or more rule(s) since the instructions for generation of executable logic may be formulated in natural language. The rule template may be a predefined rule template. The rule template may be generated to match data model(s) associated with batteries produced by using the chemical product as input material or battery types the batteries are associated with. The rule template may be generated and provided by a third party. This may allow to provide rule template(s) as a service to data providers to further simplify the generation of the chemical product data sets and to lower the entry barrier for input material suppliers to generate and provide chemical product data sets via a decentral network to allow data consumers access to such data for generation of battery passports.

[0125] In an embodiment, the one or more rule(s) are associated with or are derived from or are generated based on a semantic model, e.g. a data model, associated with batteries, in particular wherein the one or more rule(s) are defined by one or more mandatory chemical product data point(s) present within the semantic model. The data model may be associated with a battery type the battery is associated with. This may allow to avoid the use of complex data models associated with chemical product and instead may allow to use existing data models of batteries which are produced from such chemical products or battery types the batteries are associated with. This allows to significantly reduce the complexity of the generation of chemical product data sets for producers of such chemical product(s), hence ensuring reliable and efficient provision of such chemical product data set(s) within the decentral network for access by consuming entities for generation of battery passports.

[0126] In an embodiment, the one or more rule(s) define aggregation rule(s) for aggregating chemical product data gathered from multiple data sources into a given data structure, define filters to filter gathered chemical product data, define attribute construction(s) to create or add new attributes to the gathered chemical product data and / or include a trigger condition and a corresponding group of one more actions. The given data structure may be a tabular representation. Hence, the rule-based engine may be configured to generate, based on the one or more included rule(s), a tabular representation filled with gathered chemical product data matching one or more included rule(s). The tabular representation may be stored within a dedicated storage associated with the decentral data providing node, allowing provision of the tabular representation by requesting access to such tabular representation based on a chemical product identifier included in such tabular representation. Filters may define data point(s) to be included in the generated chemical product data set. For instance, a filter may define one for more chemical product property data point(s), chemical product identifier data point(s), chemical product name data point(s), chemical product producer data point(s), chemical product declaration data point(s), chemical product safety data point(s), chemical product emission data point(s), chemical product recyclate content data point(s), chemical product biobased content data point(s), chemical product biodegradability data point(s), chemical product production data point(s), chemical product certificate of analysis data point(s), chemical product certificate data point(s), chemical product life cycle data point(s), chemical product storage instruction data point(s), chemical product assembly instruction data point(s) and / or chemical product operating condition data point(s). A filter may define data point(s) per data category. A filter may define data point(s) for at least two different data categories. A data category may signify property data, declaration data, safety data, emission data, recyclate content data, biobased content data, biodegradability data, production data, certificate of analysis data, certificate data, storage instruction data, assembly instruction data or operating condition data.

[0127] In an embodiment, transforming the gathered chemical product data by the rule-based engine includes identifying one or more rule(s) applicable to the gathered chemical product data and providing the applicable rule(s) to the rule-based engine. The applicable rule(s) may be identified based on an identifier associated with each applicable rule matching or being related to at least one chemical product identifier included in the gathered chemical product data. The applicable rule(s) may be included in a rule template. Hence transforming the gathered chemical product data may include identifying an applicable rule template. The applicable rule(s) and / or the applicable rule template may be stored on a database connected to the rule-based engine. The identifier associated with each applicable rule or rule template may correspond to a digital chemical product identifier included in the gathered chemical product data. The applicable rule(s) or rule template may be gathered based on mapping data including identifier(s) associated with rule(s) or rule template(s) and associated chemical product t identifier(s) and optionally chemical product type identifier(s).

[0128] In an embodiment, transforming the gathered chemical product data includes

[0129] • generating executable logic from the one or more identified applicable rule(s),

[0130] • and transforming the gathered chemical product data by executing the generated executable logic by the rule-based engine subject to rule execution criteria.

[0131] The rule execution criteria may be included in the executable logic. The execution criteria may relate to action(s) associated with triggers included in the executable logic. Generating executable logic allows provision of rule(s) or rule template(s) as unstructured data, such as in natural language, hence simplifying creation of executable logic by using rule template(s) or rule(s) including unstructured data, such as rule(s) and / or rule template(s) written in natural language. Simplifying creation of the executable logic ensures that the barrier to generate and provide chemical product data set(s) within the decentral network is lowered, hence ensuring that also small supplier entities are able to participate as data providers within the decentral network. This in turn allows data consumers generating battery passports to reliably consume all required chemical product data via the decentral network, hence ensuring efficient and reliable generation of battery passports using the gathered chemical product data. This way, the data quality of the battery passports may be improved, allowing more reliable production of products using the battery and / or more reliable processing of end-of-life batteries based on the data included the battery passports.

[0132] In an embodiment, the chemical product data set is generated responsive to fulfilment of one or more rule(s) applied to the gathered chemical product data by the rule-based engine. This may ensure that generation of chemical product data set(s) is then performed if at least a part of the rule(s) could be successfully applied to the gathered chemical product data by the rule-based engine, e.g. if application of the rule(s) did not result in an error, for example due to missing data, wrong data, incomplete data, etc.. This may ensure that only chemical product data set(s) are provided via the decentral network which fulfil the applied rule(s), hence avoiding errors during validation performed on the consumer side which may negatively influence the data quality of generated battery passports. This may in turn have a negative influence on the provision of such batteries and products including such batteries for example if certain data from upstream production stages must be included in the battery passport from a regulatory standpoint. The delayed provision of such batteries and products including such batteries may result in a negative influence on the production of downstream participants, since required input materials are not available for production. In addition, the low data quality may negatively influence the processing of the batteries, such as end-of-life batteries, based on the data included in the battery passports.

[0133] In an embodiment, the generated chemical product data set includes or is associated with at least one chemical product identifier, in particular the chemical product identifier(s) included in the provided data associated with the chemical product. In another embodiment, the

[0134] In an embodiment, the generated chemical product data set includes at least a part of the data included in the gathered chemical product data. For instance, the generated chemical product data set may include data point(s) defined by the one or more rule(s) used to generate the chemical product data set. Such rule(s) may define one or more data point(s) to be included in the generated chemical product data set(s).

[0135] In an embodiment, the generated chemical product data set includes chemical product property data point(s), chemical product identifier data point(s), chemical product name data point(s), chemical product producer data point(s), chemical product declaration data point(s), chemical product safety data point(s), chemical product emission data point(s), chemical product recyclate content data point(s), chemical product biobased content data point(s), chemical product biodegradability data point(s), chemical product production data point(s), chemical product certificate of analysis data point(s), chemical product certificate data point(s), chemical product life cycle data point(s), chemical product storage instruction data point(s), chemical product assembly instruction data point(s) and / or chemical product operating condition data point(s). For instance, the generated chemical product data set may include chemical product emission data point(s).

[0136] In an embodiment, the method further includes a step of generating group access data associated with the generated chemical product data set and optionally one or more authorization rule(s) defining access to and / or usage of the generated chemical product data set. The group access data may identify access control groups including decentral participant identifier(s) associated with decentral network participants permitted to access at the generated chemical product data set. This access group data may allow to control access to such data sets, hence avoiding access of unauthorized data consumers to such data. This may ensure that the chemical product data sets are only shared with such data consumers that require such data, for example for the generation of battery passports.

[0137] In an embodiment, the method further includes a step of generating a contract template including the digital chemical product identifier and the group access data identifier. The method may further include a step of linking the group access data to the digital chemical product identifier. The linking may be included in the contract template. The contract template may be used by the decentral data providing node to generate an electronic contract. The electronic contract may be provided to a decentral data consuming node requesting access to such chemical product data set(s) associated with the decentral data providing node. The contract may include access data. The access data may include an endpoint pointing to the dedicated storage storing the respective chemical product data set. This may allow the decentral data consumer node to use such endpoint within the request for such chemical product data upon accepting the electronic contract. The electronic contract may include authorization rule(s) associated with the usage of the chemical product data set(s). This may avoid unauthorized use of the provided chemical product data by the data consumer, hence improving data security.

[0138] In an embodiment, the access to the generated chemical product data set is controlled by the decentral data providing node associated with the data owner based on the group access data and contract template associated with the chemical product data set. This may allow to configure access to the chemical product data set such that access to such data by unauthorized data consumers not requiring access to such data is avoided. Access to the generated chemical product data set may be controlled based on the digital chemical product identifier associated with the chemical product data set and the chemical product.

[0139] In an embodiment, the method further includes a step of generating incident data responsive to the determination that at least one rule applied by the rule-based engine to the gathered chemical product data is not fulfilled. The incident data may identify the data point(s) and rule(s) which resulted in non- fulfillment. The incident data may be used to generate an updated chemical product data set. Use of such incident data may allow to avoid provision of chemical product data sets which may not be validated by the consumer side, thus resulting in delay of generation of battery passport(s) since such generation must be delayed until chemical product data set(s) including valid data are available from the provider side.

[0140] In an embodiment of the method for validating chemical product data associated with chemical product(s), the battery data further includes product property data including at least one measured chemical and / or physical property of the battery and / or at least one chemical and / or physical property determined from collected data associated with the production of the battery. The chemical and / or physical property may correspond to the properties previously described. The data may be collected prior to, during and / or after production of the battery.

[0141] In an embodiment of the method for validating chemical product data associated with chemical product(s), the decentral data providing node(s) are determined from mapping data mapping decentral data providing node data to associated chemical product identifiers by matching chemical product identifier(s) included in the chemical product data to chemical product identifier included in the mapping data. This mapping data may be stored in a database. The database may be associated with the data consumer or the entity performing the method. The database may be associated with the system performing the method. The chemical product identifiers may include asset identifier(s) associated with the chemical product data. The asset identifier(s) and associated data providing node data may be provided by respective decentral data providing node(s) to the consuming entity consuming such chemical product data from such data providing node(s). Data providing node data may include location data pointing to the location of the chemical product data associated with the respective data providing node, an endpoint address associated with the respective data providing node and / or a decentral participant identifier associated with the respective data providing node. The database may not contain associated chemical product data, hence the database may not be regarded as a central repository of chemical product data. Instead, the control over access to the chemical product data is retained by the respective data providers, while such database only allows to locate chemical product data required to generate respective battery passports.

[0142] In an embodiment of the method for validating chemical product data associated with chemical product(s), the obtained chemical product data is provided to one or more input node(s) configured to gather the obtained chemical product data and to provide the gathered chemical product data as chemical product data set(s) to one or more downstream node(s), wherein the one or more downstream node(s) are configured to validate at least a part of the data included in the chemical product data set(s) provided by the one or more input node(s), link the validated chemical product data to at least one of the battery identifiers, determine storage location(s) for the validated chemical product data and to provide the validated chemical product data linked to battery identifier(s) to the determined storage location(s). An input node may represent a computing node gathering chemical product data from one or more decentral data consuming node(s). The one or more input node(s) may be configured to generate data packages, such as messages or events, from the received chemical product data. The generated data packages may be sent downstream from the input node to the one or more downstream node(s). The downstream node(s) may be configured to retrieve data packages provided by the input node(s). The input node(s) may be configured to provide data packages to a persistent or non-persistent log. The downstream node(s) may be configured to retrieve data packages provided to the persistent or non-persistent log. The downstream node(s) may be configured to receive data packages provided to the persistent or non- persistent log. The input node(s) may be associated with a decentral network. For instance, the input node(s) may be associated with a decentral data consuming network node being part of a decentral network. Downstream node may refer to a computing node consuming data from a computing node present upstream with respect to the flow of data. Consuming data may include receiving data or retrieving data packages from the input node(s) or the persistent or non-persistent log. For instance, data “flows” downstream from an input node to the downstream node. The downstream node may be regarded as an output node. A request for data may be sent upstream from the downstream node to the input node.

[0143] In an embodiment of the method for validating chemical product data associated with chemical product(s), the rule-based engine operates on individual data points present within at least part of the chemical product data, multiple data points present within at least part of the chemical product data or the whole chemical product data. The rule-based engine may be configured to validate chemical product data based on one or more included rule(s). The rule-based engine may apply one or more rule(s) to individual data point(s), multiple data point(s) and / or the whole data set to generate validated chemical product data. If the rule-based engine determines that individual data point(s), multiple data point(s) and / or the whole data matches one or more condition(s) in the rule(s), such individual data point(s), multiple data point(s) or the whole data may be regarded as validated. The validated data may be associated with a classifier indicating successful validation of the respective data point, combination of data point(s) or the whole data. The classifier may indicate that the chemical product data passed the one or more applied rule(s). Validating the chemical product data on data point level may ensure that all chemical product data point(s) required by the data model associated with the battery or battery type are contained in the gathered chemical product data. Validation on data point level may compensate for the simplified chemical product data set generation at the provider side which does not require the use of data models ensuring that the generated chemical product data set(s) include all required data point(s).

[0144] In an embodiment of the method for validating chemical product data associated with chemical product(s), the one or more rule(s) are generated from a rule template including unstructured data associated with instructions related to validation operation(s). The validation operation(s) may relate to one or more data point(s) and / or data point combination(s) to be present within the chemical product data. The rule template may be used to generate executable logic that may be executed by the rule-based engine. Use of a rule template may facilitate generation of one or more rule(s) since the instructions for generation of executable logic may be formulated in natural language. The rule template may be a predefined rule template. The rule template may be generated to match data model(s) associated with batteries or battery types.

[0145] In an embodiment of the method for validating chemical product data associated with chemical product(s), the one or more rule(s) define data point(s) and / or combination(s) of data point(s) to be present within the chemical product data. This may ensure that the chemical product data includes all data point(s) required by the data model associated with batteries or battery types, hence ensuring that the gathered chemical product data includes all data points required by the data model for the particular chemical product.

[0146] In an embodiment of the method for validating chemical product data associated with chemical product(s), validation of the chemical product data may further include transforming the chemical product data. Transforming the chemical product data may include unit transformation to transform a unit associated with a data point into a unit required by the data model associated with batteries or battery types. This may allow to shift unit transformation operations to the consumer side, hence allowing to simplify generation of chemical product data sets at the provider side to ensure reliable provision of chemical product data set(s) by various suppliers of the battery ecosystem, irrespective of the size of the entity producing the chemical products.

[0147] In an embodiment of the method for validating chemical product data associated with chemical product(s), the one or more rule(s) are associated with or derived from a data model associated with at least one of the batteries or battery types, in particular wherein the one or more rule(s) are defined by the mandatory chemical product data point(s) present within the data model. The data model may be a predefined (e.g. existing) data model. The data model may define the data structure of the battery passport. The data model may define the value(s) and / or value range(s) for data point(s) to be included in the battery passport. The ata model may define mandatory and optional data point(s) to be included in the battery passport. The data model may define relationships between different data point(s).

[0148] In an embodiment of the method for validating chemical product data associated with chemical product(s), validating the gathered chemical product data by the rule-based engine includes identifying one or more rule(s) applicable to the gathered chemical product data and providing the applicable rule(s) to the rulebased engine. The applicable rule(s) may be identified based on an identifier associated with each applicable rule matching or being related to at least one chemical product identifier included in the gathered chemical product data as previously described. The applicable rule(s) may be included in a rule template. Hence validating the gathered chemical product data may include identifying an applicable rule template. The applicable rule(s) and / or the applicable rule template may be stored on a database connected to the rule-based engine. The identifier associated with each applicable rule or rule template may correspond to a digital chemical product identifier included in the gathered chemical product data. The applicable rule(s) or rule template may be gathered based on mapping data include identifier(s) associated with rule(s) or rule template(s) and associated chemical product identifier(s) and optionally chemical product type identifier(s).

[0149] In an embodiment of the method for validating chemical product data associated with chemical product(s), transforming the gathered chemical product data includes

[0150] • generating executable logic from the one or more identified applicable rule(s),

[0151] • and transforming the gathered chemical product data by executing the generated executable logic by the rule-based engine subject to rule execution criteria.

[0152] In an embodiment of the method for validating chemical product data associated with i chemical product(s), the chemical product data is validated responsive to fulfilment of one or more rule(s) applied to the chemical product data by the rule-based engine. This may ensure that the gathered chemical product data is only validated if the rule(s) could be successfully applied to the gathered data by the rulebased engine, e.g. if application of the rule(s) did not result in an error, for example due to missing data, wrong data, incomplete data, etc.. This may ensure that the battery passport may be generated by applying the respective data model to the validated chemical product data and respective battery data without any errors due to missing or wrong chemical product data, hence avoiding a delay in generation of the battery passports.

[0153] In an embodiment of the method for validating chemical product data associated with chemical product(s), the storage location is determined based on mapping data including a mapping between chemical product identifier(s) and associated storage location data or a mapping between chemical product identifier(s) and associated chemical product type identifier(s) and storage location data. The storage location may correspond to a database. The database may be a relational or a non-relational database. Use of different storage location(s) allows to improve data security, since validated data to be used for the generation of battery passports associated batteries, may be stored within a particular dedicated storage accessible only by the application generating the battery passports for such batteries but not for other applications generating passports for other product types.

[0154] In an embodiment of the method for validating chemical product data associated with chemical product(s), the validated data includes one or more validated chemical product property data point(s), validated chemical product identifier data point(s), validated chemical product name data point(s), validated chemical product producer data point(s), validated chemical product declaration data point(s), validated chemical product safety data point(s), validated chemical product emission data point(s), validated chemical product recyclate content data point(s), validated chemical product biobased content data point(s), validated chemical product biodegradability data point(s), validated chemical product production data point(s), validated chemical product certificate of analysis data point(s), validated chemical product certificate data point(s), validated chemical product life cycle data point(s), validated chemical product storage instruction data point(s), validated chemical product assembly instruction data point(s) and / or validated chemical product operating condition data point(s). In an embodiment of the method for validating chemical product data associated with chemical product(s), the method further includes a step of generating incident data responsive to the determination that at least one rule applied by the rule-based engine to the gathered chemical product data is not fulfilled. The incident data may identify the data point(s) and rule(s) which resulted in non-fulfilment. The incident data may be provided to the data provider from which the objected input chemical product data was received, hence allowing the data provider to generated updated chemical product data and to provide such updated chemical product data for repeated validation.

[0175] DETAILED DESCRIPTION

[0176] FIG. 1 illustrates an example of a participant network of a product ecosystem associated with a decentral peer-to-peer network for exchange of data associated with raw materials, chemical product(s), discrete product(s), end product(s) and recycled material(s). The decentral participant network 130 may include one or more decentral network participants, such as decentral participants 102 to 114. The decentral network participants may be part of a product ecosystem including chemical products. The product ecosystem may include production chains to produce an end-product. The product ecosystem may include recycling chains to recycle at least part of an end-of-life product resulting from the use of the end product. The product ecosystem may include a raw material producer 104, a chemical product producer 102, a chemical product user 106, an end-product producer 108, an end-product user 110 an EOL product collector 112 and a recycler 114. The decentral participant network 130 may include a chemical supply chain. The product ecosystem may allow to use of recycled materials resulting from recycling of end-of- life products to produce new products, such as chemical products. The product ecosystem may be associated with the production and / or recycling of physical products. The product may be a chemical product, an intermediate chemical product, a chemical product, a chemical product assembly, an end product, an end-of-life product or a recycled material.

[0177] At least a part of the participant(s) of the decentral participant network 130 may be associated with the production of the product and / or the recycling of end-of-life products resulting from the use of the product by product users, such as end-product users 110. The decentral network participant 102 to 114 may refer to a manufacturer of physical products, such as raw material producer 104, chemical product producer 102, chemical product user 106, end-product producer 108, a user of physical goods, such as end-product user 110, and / or a participant of a recycling chain associated with the physical product, such as EOL product collector 112 and recycler 114. The decentral network participant may be associated with a decentral participant identifier. The decentral participant identifier may uniquely identify the decentral network participant within the decentral participant network 130.

[0178] At least a further part of the participant(s) of the decentral participant network 130 may be associated with the generation of product passport(s). Such decentral participants may not be associated with the production of the product and / or the recycling of the end-of-life products. Such decentral participants may gather chemical product data, for example as described in the context of FIG. 14 and may generate product passports using at least a part of the gathered chemical product data. The generated product passports may be provided by such participants for access via the decentral network 130. For instance, recycler 114 may access such product passports to determine the composition of the end-of-life product, allowing adaption of the recycling process to the determined composition.

[0179] The participant(s) of the decentral participant network 130 may be connected via material flows. The material flow may be a loop material flow 136. The loop material flow 136 may be a closed loop material flow. A closed loop material flow may refer to a material loop where recycled material is used to produce the same end products the recycled material is obtained from via recycling. The loop material flow 136 may be an open loop material flow. An open loop material flow may refer to a material loop where recycled material is used to produce different end products than the one the recycled material is obtained from. The material flow may be a linear material flow (e.g. not including recycling). The material flow 136, 138 may correspond to the flow of product from one participant of the decentral participant network 130 to the downstream participant ofthe decentral participant network 130. The material flow 136, 138 may refer to a continuous or a discontinuous flow of product. The flow of product may include any means of transportation suitable to transport the product from a participant to the downstream participant. The means of transportation may include pipes, containers, barrels, packages. The material flow 138 may be associated with raw materials used to produce a chemical product, such as virgin raw materials. The raw materials may be provided to chemical product producer 102 for producing chemical product(s) and / or intermediate chemical product(s) (not shown). The loop material flow 136 may be associated with chemical product(s) and discrete product(s). The chemical product(s) may be provided from chemical product producer 102 to chemical product user 106 for producing discrete product(s). In contrast to chemical production, the discrete products being produced are distinct units sold as individual products. The loop material flow 136 may be associated with recycled material. The recycled material may be provided from recycler 114 to chemical product producer 102 for the production of chemical product(s) using the recycled material.

[0180] At least part of the participants of the decentral participant network 130 may be associated with decentral participant network nodes 116 to 128. The decentral participant nodes 116 to 128 may be under control of the respective decentral participant associated with the respective decentral participant node. The decentral participant nodes 116 to 128 may form decentral network 134. The decentral network 134 may be a peer-to-peer communication network. The decentral network 134 may be configured to perform data transactions 132. The data transactions 132 may be based on a transaction protocol including authentication and / or authorization mechanism(s). Based on the authentication and / or authorization mechanism(s) a peer-to-peer communication between decentral network nodes 116 to 128 associated with decentral network participants 102 to 114 may be established. The one or more authentication mechanism(s) may be associated with or linked to an identifier as described in the context of FIG. 8. The one or more authentication mechanism(s) associated with the identifier may be accessible by the decentral participant nodes as described in the context of FIG. 8. The decentral configuration allows for more efficient use of computing resources and strengthens control by the data owners of the decentral network.

[0181] Data transactions between decentral network participant nodes may be based on an identifier associated with respective data to be accessed, for example as described in the context of FIG. 8. The identifier may be uniquely associated with the physical entity of the respective product and associated product data. The identifier may be a decentral identifier uniquely identifying the product within the decentral network. The identifier may be a local identifier used by the respective product producer to uniquely identify the respective product. The identifier may be associated with further identifier(s), such as identifier(s) of production input(s) (e.g. input materials) used to produce the chemical product. This may allow to track the product input(s) used to produce a product, such as an end-product. The identifier may, for example, be included in a chemical product data set associated with the battery chemical product, for example as described in the context of FIG. 9.

[0182] The data flow 132 (e.g. transactions) between decentral network participant nodes may be directly or indirectly associated with the material flow 136, 138 between the decentral network participants. For instance, data flow 132 may be directly associated with material flow 136, 138 if data associated with an input material provided from the raw material producer 104 to the chemical product producer 102 is accessed by decentral participant node 118 associated with said chemical product producer 102. For instance, data flow 132 may be indirectly associated with material flow 136, 138 if data associated with a chemical product produced by chemical product producer 102 is accessed by decentral participant node 128 associated with recycler 114.

[0183] The decentral participant nodes 116 to 128 may be decentral computing nodes. The decentral computing node may be any device or system that includes at least one physical and tangible processor, and a physical and tangible memory capable of having thereon computer-executable instructions that are executed by a processor. The memory may take any form and depends on the nature and form of the computing node.

[0184] At least part of the decentral participant nodes 116 to 128 may be decentral data providing network nodes. At least part of the participant nodes 116 to 128 may be decentral data consuming network nodes. A participant of the decentral participant network 130 may be associated with a decentral data providing network node and / or a decentral data consuming network node depending on whether data is provided to downstream participants and / or consumed from upstream participants. For instance, end-product producer 108 may be associated with a decentral data providing network node configured to provide product data to a downstream participant (e.g. recycler 114). In addition to or alternatively, end-product producer 108 may be associated with a decentral data consuming network node configured to access data associated with a discrete product produced by an upstream participant (e.g. chemical product user 106) for example as described in the context of FIG. 8.

[0185] The decentral network 134 may include further decentral network nodes. The further decentral network nodes may be decentral infrastructure service nodes (not shown in FIG. 1). The decentral infrastructure service nodes may not be associated with a participant of the product ecosystem. The decentral infrastructure service nodes may provide services for decentral participant nodes 116 to 128, such as verifying the identity of the decentral network participant nodes 116 to 128 prior to performing a data exchange. The decentral network participant nodes 116 to 128 may be associated with or include certificate(s), such as X.509 certificate(s). The certificate(s) may be associated with decentral infrastructure service node(s) including e.g. a certificate issuing service and / or a dynamic provisioning service providing dynamic attribute tokens (e.g. OAuth Access Tokens). This way the decentral network participant nodes 116 to 124 possess a unique identifier embedded in a X.509 certificate that identifies the respective decentral network participant node 116 to 128. The information required to verify the certificate may be provided via an authentication registry associated with the certificate issuing service and / or a dynamic provisioning service. For instance, in the IDSA Reference Architecture Model, Version 3.0 of April 2019, a decentral data providing network node associated with a data owner, a Certification Authority (CA), a Dynamic Attribute Provisioning Service (DAPS) and a decentral data consuming network node associated with a data consumer are used to verify the identity prior to performing a data exchange (not shown, refer to FIG. 8). FIG. 2 illustrates an example of a participant network of a battery ecosystem including a material loop and being associated with a decentral peer-to-peer network for exchange of data associated with raw materials, chemical product(s), batteries, end product(s) and recycled material(s). The decentral participant network 216 may include one or more decentral network participants, such as decentral network participants 108, 112 and 202 to 212. The battery ecosystem may include production chains to produce an end product, such as a machine containing a battery. The battery ecosystem may include recycling chains to recycle at least part of an end-of-life battery resulting from the use of the end product. The battery ecosystem may include a miner 202, a refiner 204, a precursor cathode active material (PCAM) and cathode active material (CAM) producer 206, a battery producer 208, an end-product producer 108, an EOL product collector 112, a black mass producer 210 and a metal extractor 212. The battery ecosystem may allow to use recycled materials, such as recycled metals and metal salts, resulting from recycling of end-of-life batteries or chemical products thereof to produce new products, such as PCAM and CAM. The product ecosystem may be associated with the production and / or recycling of batteries.

[0186] The participant(s) of the decentral participant network 216 may be associated with the production of a battery containing end product and / or recycling of end-of-life batteries or chemical products thereof. The decentral network participant may be a manufacturer of physical products, such as miner 202, refiner 204, PCAM & CAM producer 206, chemical product producer 102, chemical product user 106, endproduct producer 108 and / or a participant of a recycling chain associated with the end-of-life batteries or chemical products thereof, such as EOL product collector 112, black mass producer 210 and metal extractor 212. For instance, the metal extractor 212 and the PCAM & CAM producer 206 may be a single entity performing recycling operations to obtain recycled material, such as recycled metals and / or metal salts, and producing new chemical product(s), such as PCAM and / or CAM using the recycled metal and / or metal salts. The decentral network participant may be associated with a decentral participant identifier. The decentral participant identifier may uniquely identify the decentral network participant within the decentral participant network 216.

[0187] At least a further part of the participant(s) of the decentral participant network 208 may be associated with the generation of battery passport(s). Such decentral participants may not be associated with the production of the battery containing end product and / or the recycling of the end-of-life batteries or chemical products. Such decentral participants may gather chemical product data, for example as described in the context of FIG. 14 and may generate battery passports using at least a part of the gathered chemical product data. The generated battery passports may be provided by such participants for access via the decentral network 130. For instance, recycler 114 may access such battery passports to determine the chemical composition of the end-of-life batteries or chemical products thereof, allowing adaption of the recycling process to the determined composition. The participant(s) of the decentral participant network 216 may be connected via material flows as described in the context of FIG. 1 . The raw materials, such as metals, may be provided to refiner 204 for refinement. The refined metals may be provided to PCAM & CAM producer 206 for the production of cathode active material. The CAM may be used, for example by battery producer 208, to produce battery cells (see also FIG. 3A to FIG. 3C). The battery cells may be used to produce batteries or battery packs (see also FIG. 3B). The batteries or battery packs may be provided to end-product producer 108 to produce battery containing end products, such as electric vehicles. Scrape from battery production may be provided to black mass producer 210.

[0188] At least a part of the participants of the decentral participant network 216 may be associated with decentral participant network nodes 218 to 232 as described in the context of FIG. 1. The decentral participant nodes 218 to 232 may form decentral network 208. The decentral network 208 may be a peer- to-peer communication network as described in the context of FIG. 1 . The decentral configuration allows for more efficient use of computing resources and strengthens control by the data owners of the decentral network.

[0189] Data transactions between decentral network participant nodes may be based on an identifier associated with respective data to be accessed, for example as described in the context of FIG. 8. The identifier may be uniquely associated with the physical entity of the respective product and associated product data. The identifier may be a decentral identifier uniquely identifying the product within the decentral network. The identifier may be a local identifier used by the respective product producer to uniquely identify the respective product. The identifier may be associated with further identifier(s), such as identifier(s) of production input(s) (e.g. input materials) used to produce the chemical product. This may allow to track the product input(s) used to produce a product, such as an end-product. The identifier may, for example, be included in chemical product data associated with chemical products, for example as described in the context of FIG. 14.

[0190] The data flow 132 (e.g. transactions) between decentral network participant nodes may be directly or indirectly associated with the material flow 136, 138 between the decentral network participants as described in the context of FIG. 1 .

[0191] The decentral participant nodes 218 to 232 may be decentral computing nodes as described in the context of FIG. 1.

[0192] At least part of the decentral participant nodes 218 to 232 may be decentral data providing network nodes. At least part of the participant nodes 116 to 128 may be decentral data consuming network nodes. A participant of the decentral participant network 130 may be associated with a decentral data providing network node and / or a decentral data consuming network node depending on whether data is provided to downstream participants and / or consumed from upstream participants (see also FIG. 1). The decentral network 206 may include further decentral network nodes as described in the context of FIG. 1.

[0193] FIG. 3A to FIG. 3C illustrate a schematic block diagram of a production process of a battery.

The rule(s) may define key-value pair(s) to be included in the generated chemical product. The rule(s) may define value(s) to be included in the generated chemical product. The rule(s) may define unit(s) for data point(s) and / or one or more conversion(s) to convert a unit associated with a data point into another unit. The rule(s) may define key-value pair(s) for chemical product property data, chemical product identifier data, chemical product name data, chemical product producer data, chemical product declaration data, chemical product safety data, emission data, chemical product recyclate content data, chemical product biobased content data, chemical product biodegradability data, chemical product production data, chemical product certificate of analysis data, chemical product certificate data, chemical product life cycle data, chemical product storage instruction data, chemical product assembly instruction data and / or chemical product operating condition data. A rule may define key-value pairs for per data category. A rule may define key-value pairs for at least two different data categories. A data category may signify property data, declaration data, safety data, emission data, recyclate content data, biobased content data, biodegradability data, production data, certificate of analysis data, certificate data, storage instruction data, assembly instruction data or operating condition data. Gathered data may be aggregated and filtered to extract the value(s) matching the key(s) defined in the rule(s) from the aggregated data The generated chemical product data sets may include one or more data points. The chemical product data sets may include one or more key-value pairs. The generated chemical product data sets may include at least a part of the gathered chemical product data. The generated chemical product data set(s) may include chemical product property data point(s), chemical product identifier data point(s), chemical product name data point(s), chemical product producer data point(s), chemical product declaration data point(s), chemical product safety data point(s), chemical product emission data point(s), chemical product recyclate content data point(s), chemical product biobased content data point(s), chemical product biodegradability data point(s), chemical product production data point(s), chemical product certificate of analysis data point(s), chemical product certificate data point(s), chemical product life cycle data point(s), chemical product storage instruction data point(s), chemical product assembly instruction data point(s) and / or chemical product operating condition data point(s). The chemical product data set(s) may include at least a part of the gathered chemical product data in tabular form. Use of rule(s) associated with a battery produced from such chemical product(s) allows to ensure that chemical product data point(s) required according to a data model, such as an aspect model, associated with batteries or battery types are contained in the chemical product data set, hence avoiding missing data point(s) during generation of battery passport associated with batteries using said data model. The transformation allows to aggregate the gathered chemical product into a given data data structure, such as a tabular data structure, without the use of complex data models, hence facilitating generation and sharing of chemical product data set(s) within the battery ecosystem. Such sharing may enable more efficient production and / or recycling processes based on the shared chemical product data, for instance chemical product composition data. The tabular data structure can be readily consumed via a decentral network by a consumer backend configured to verify the consumed data and to persist verified consumed data to data storages for generation of battery passports (see for example FIG. 13A and FIG. 13B). Verification by the consumer side ensures that the battery passport contains all data required by a data model used to generate such passport, hence allowing to reduce the complexity associated with the chemical product data set generation at the provider side by avoiding the use of complex ata models during generation of the chemical product data set(s). This may enable reliable sharing of chemical product data of chemical product(s) irrespective of the existence of data models for such chemical products since the rule(s) required to transform the gathered chemical product data may be readily derived from or generated based on the data model associated with batteries or battery types.

[0222] Data transforming unit 624 may further be configured to provide the generated chemical product data set(s) (hereinafter also referred to as asset(s)) to data provider unit 644. Data provider unit 644 may be configured to provide the received chemical product data set(s) to a database for storage, such as assets DB 604. The asset(s) may include or be associated with the digital chemical product identifier associated with the chemical product. The asset(s) may include or be associated with a chemical product identifier (e.g. asset identifier) associated with the chemical product and the chemical product data set. This may allow to retrieve the asset based on the digital chemical product identifier and / or the asset identifier. The asset(s) may be persisted by data transforming unit 624 in assets DB 604. Assets DB 604 may be configured to store chemical product data set(s) generated by data transforming unit 624. Assets DB 604 may be configured to provide chemical product data set(s) to data transfer service 602.

[0223] Data provider unit 644 may further be configured to provide data included in the generated chemical product data set(s), such as the digital chemical product identifier, to asset publisher service 608.

[0224] Asset publisher service 608 may be configured to generate group access data associated with the respective chemical product data set. The group access data may identify access control groups including decentral participant identifier(s) associated with decentral network participants permitted to access at the respective chemical product data set. The group access data may include a group access data identifier. The group access data may further identify one or more authorization rule(s) defining access to and / or usage, e.g. processing, of the chemical product data set by the data consumer(s). Asset publisher service 608 may further be configured to generate a contract template including the digital chemical product identifier and the group access data identifier. Asset publisher service may be configured to link the group access data to the chemical product data set, for example via the asset identifier of the chemical product data set. The contract template may hence be associated with the chemical product data set as well as respective group access data. The contract template may further include access data associated with assets DB 604. The access data may include a locator or pointer to the assets DB 604 storing the respective chemical product data set. This may allow to access the respective chemical product data set based on data included in the contract template, e.g. the digital chemical product identifier and the access data. The group access data and contract template may be generated by asset publisher service 608 per data included in the chemical product data set, for example per digital chemical product identifier. The generated group access data and contract template may be provided to decentral data providing node 118 connected to asset generation system 646.

[0225] Decentral data providing node 118 may be part of a decentral network, such as decentral network 134 described in the context of FIG. 1 and FIG. 2. Decentral data providing node 118 may be configured to provide chemical product data set(s) in response to a request received from decentral data consuming node(s), for example as described in the context of FIG. 8. Decentral data providing node 118 may be configured to control access to chemical product data set(s) based on associated group access data and contract template generated by asset publisher service 608, for example as described in the context of FIG. 8. Decentral data providing node 118 may be associated with a participant of the battery ecosystem, such as a producer of the chemical product(s).

[0226] Data transfer service 602 may be configured to gather chemical product data set(s) from assets DB 604 in response to a request from decentral data providing node 118. Data transfer service 602 may be configured to fetch asset metadata from assets DB 604 based on data received from decentral data providing node 118. Data transfer service 602 may be configured to parse the fetched metadata to determine group access data associated with the respective chemical product data set and / or the storage location of the respective chemical product data set. Data transfer service 602 may be configured to gather respective chemical product data set(s) from assets DB 604 based on the fetched metadata. Data transfer service 602 may be configured to provide the gathered chemical product data set(s) to decentral data providing node 118.

[0227] The system may not comprise a decentral registry storing access elements allowing access to the chemical product data set(s) stored in assets DB 604. Hence, chemical product data set(s) may not be located by querying the decentral network using the digital chemical product identifier but may only be accessed directly from decentral data providing node 118 using the digital chemical product identifier. Hence, location data pointing to the dedicated storage storing the chemical product data set as well as the chemical product identifier may be required to access the respective chemical product data set. The location data in combination with the chemical product identifier of the chemical product data set may result in a unique identifier allowing to uniquely identify a given chemical product data set within the decentral network.

[0228] FIG. 6B illustrates a diagram showing an example of gathering chemical product data and transforming at least part of the gathered chemical product data using a rule-based engine. Transforming at least a part of the gathered chemical product data may result in generation of chemical product data set(s) as described in the context of FIG. 6A.

[0229] Data transforming unit 624 may include rule based engine 628. The rule based engine 628 may operate on individual data point(s), multiple data point(s) and / or the gathered chemical product data. The rule based engine 628 may operate on data gathered per chemical product identifier individually. This allows to transform gathered chemical product data per chemical product, hence allowing a more granular transformation of the chemical product data. Rule based engine 628 may receive a request to transform gathered chemical product data. The request may contain at least a part of the gathered chemical product data. Chemical product data may be gathered (see operation 626) by data gathering unit 622 from a data source layer 620 as described in the context of FIG. 6A. Rule based engine 628 may be configured to determine chemical product identifier(s) associated with the chemical product data. For instance, rule based engine 628 may parse the received chemical product data to determine the respective chemical product t identifier(s). The rule based engine 628 may have access to one or more rule(s). The rule based engine 628 may include one or more rule(s). The one or more rule(s) may be present within a rule template. The one or more rule(s) may be stored in a data storage, such as rule DB 612. The one or more rule(s) or rule template(s) may be provided to rule DB 612 by a user. The one or more rule(s) may correspond to unstructured data associated with instructions related to transformation operation(s). The rule template(s) may correspond to unstructured data associated with instructions related to transformation operation(s). The one or more rule(s) or the rule template may be included in a file provided by the user. The one or more rule(s) or the rule template(s) may be associated with chemical product type identifier(s) and / or chemical product data identifier(s). Rule based engine 628 may generate a request to obtain one or more rule(s) from rule DB 612. The request may contain the respective chemical product identifier(s).

[0230] One or more rule(s) associated with the chemical product data to be transformed (e.g. one or more applicable rule(s)) may be provided to rule based engine 628 in response to the request. The one or more rule(s) may be associated with batteries produced from the chemical product associated with the chemical product data to be transformed may be used as input material to produce the respective battery. The one or more rule(s) may be associated with or derived from or generated based on a data model associated with at least one of the batteries or battery types. Hence, the one or more rule(s) may ensure that data point(s) for such chemical products required according to the data model may be included in the generated chemical product data set. The one or more rule(s) may be defined by the mandatory chemical product data points present within the data model. The one or more rule(s) may be generated based on the mandatory chemical product data points present within or defined by the data model. This may ensure that chemical product data required by the data model is included in the generated chemical product data set. The one or more rule(s) may be associated with chemical product identifier(s) and / or chemical product type identifier(s). A mapping table may be used to map chemical product identifier(s) to corresponding chemical product type identifier(s). The chemical product type identifier(s) may be associated with chemical product type(s). The mapping table may be stored in a separate database (not shown). Rule based engine 628 may be configured to gather chemical product type identifier(s) based on determined chemical product identifiers) and to request rule(s) based on the gathered chemical product type identifier(s). This may allow to gather rule(s) associated with chemical product type identifier(s) based on chemical product identifier(s), hence avoiding generation of rule(s) per chemical product identifier and reducing the number of rule(s) that need to be generated, stored and maintained in rule DB 1318..

[0231] The one or more rule(s) may define aggregation rule(s) for aggregating chemical product data gathered from multiple data sources into a given data structure. The given data structure may be a tabular representation. Aggregation may hence result in filling gathered chemical product data into a tabular data structure. The one or more rule(s) may define filters to filter gathered chemical product data. The filters may be associated with or relate to the data model associated with at least one of the batteries or battery types. The filters may define data point(s) to be included in the generated chemical product data set. For instance, a filter may define one for more chemical product property data point(s), chemical product identifier data point(s), chemical product name data point(s), chemical product producer data point(s), chemical product declaration data point(s), chemical product safety data point(s), chemical product emission data point(s), chemical product recyclate content data point(s), chemical product biobased content data point(s), chemical product biodegradability data point(s), chemical product production data point(s), chemical product certificate of analysis data point(s), chemical product certificate data point(s), chemical product life cycle data point(s), chemical product storage instruction data point(s), chemical product assembly instruction data point(s) and / or chemical product operating condition data point(s). A filter may define data point(s) per data category. A filter may define data point(s) for at least two different data categories. A data category may signify property data, declaration data, safety data, emission data, recyclate content data, biobased content data, biodegradability data, production data, certificate of analysis data, certificate data, storage instruction data, assembly instruction data or operating condition data. This may ensure that chemical product data required by the data model is included in the generated chemical product data set. The one or more rule(s) may define attribute construction(s) to create or add new attributes to the gathered chemical product data. The one or more rule(s) may define manipulation(s) to convert chemical product data point(s). For instance, data point(s) present within the gathered chemical product data may be converted from one unit into another unit. This may ensure that the generated chemical product data set includes data points associated with a unit required by the data model. The one or more rule(s) may include a trigger condition and a corresponding group of one more actions. The trigger conditions may involve a set of variables, sometimes called “working memory”, which may contain data (sometimes called “facts” or “data tuples”) representing the states of pertinent real-world items. The one or more action(s) may include attribute construction, filters and / or manipulations. A given chemical product identifier and / or chemical product identifier may be associated with rule(s) defining aggregation, rule(s) defining filters, rule(s) defining attribute construction, rule(s) defining manipulations and / or rule(s) including a trigger condition and action(s). The rule(s) may be associated with a given order.

[0232] Rule based engine 628 may be configured to initialize the rule engine (see operation 632). Initialization of the rule engine may include generating rule data executable by a processor included in rule based engine 628. The rule data may include or correspond to executable logic. This may allow to transform rule(s) or rule template(s) present in unstructured data form into code that can be executed by the processor. Execution of the code may result in applying the executable rule data to the gathered chemical product data (see operation 634) to transform the chemical product data according to the obtained rule(s). Execution of the logic may result in matching gathered chemical product data to condition(s) included in the executable logic, evaluating the condition(s) with matched chemical product data and triggering execution of rule actions based on condition evaluation results. Transforming the chemical product data may include filtering gathered chemical product data. Filtering the gathered chemical product data may include comparing individual data points present within the gathered chemical product data to data points defined by the filter(s) to determine chemical product data points to be included in the chemical product data set. Transforming the chemical product data may include comparing attributes of the gathered or filtered chemical product data to attributes defined in rule(s) to determine whether new attributes have to be created or added to the gathered or filtered chemical product data. In addition or alternatively, transforming may include comparing attribute(s) included in the gathered or filtered chemical product data or chemical product data including added or created attribute(s) to attribute(s) included in the modification rule(s). The modification rule(s) may include a trigger condition which may be associated with one or more action(s), for example unit conversion, if the trigger condition is satisfied and / or error handling if application of filters results in empty data points due to lack of data points in the gathered chemical product data. The trigger condition may be satisfied if the attribute(s) included in the gathered or filtered chemical product data or chemical product data including added or created attribute(s) are not matching attribute(s) defined in the modification rule(s). Operations performed by rule based engine 628 may be determined by rule(s) gathered from rule DB 612. For instance, rule(s) gathered from rule DB 612 may determine whether rule based engine 628 operates on individual data point(s) and / or multiple data point(s) and / or the whole gathered chemical product data.

[0233] Rule based engine 628 may be configured to determine whether the gathered chemical product data can be transformed by one or more applied rule(s) (see operation 636). Gathered chemical product data may not be transformed or only partially transformed (e.g. transformation may result in at least one error associated with applying one or more obtained rule(s) to the gathered chemical product data) if the gathered chemical product data does not include data point(s) required according to one or more obtained rule(s). Rule based engine 628 may provide the generated chemical product data set to assets DB 604 responsive to the gathered chemical product data being successfully transformed (e.g. responsive to generation of a chemical product data set by applying one or more obtained rule(s) without resulting in an error.

[0234] If at least a part of the gathered chemical product data could not be transformed, rule based engine 628 may proceed to operation 638. In operation 638, rule based engine 628 may generate message data indicating that at least part of the gathered chemical product data could not be transformed. The message data may include an indication which data point(s) of the gathered chemical product data could not be transformed. The message data may be provided to a display device configured to display data received from rule based engine 628. The display device may comprise a graphical user interface 640. The display device may display the message in response to receiving message data from rule based engine 628. This allows to trigger correction or updating of data point(s) identified as not matching one or more of the obtained rule(s). After correction or updating of respectively identified data point(s), gathering and transformation of updated or corrected chemical product data may be initiated.

[0235] FIG. 8 illustrates an example of a decentral system for accessing data associated with chemical product(s). The chemical product may be a chemical product as described in the context of FIG. 6. The chemical product may be any chemical product produced by upstream production stage(s) with respect to the battery pack production stage. The decentral system may be a decentral peer-to-peer network 134, 208 as described in the context of FIG. 1 and FIG. 2.

[0236] The chemical product may be associated with chemical product data set(s). Chemical product data set(s) may be generated as described in the context of FIG. 6A to FIG. 7. The chemical product data set(s) may be stored in assets DB 604 associated with data transfer service 602. Assets DB 604 may be associated with a decentral provider node 118. The decentral provider node may be associated with a decentral network participant. The decentral network participant may be the producer of the chemical product. The decentral network participant may be the data owner of the chemical product data set(s) stored in assets DB 604. The chemical product data set(s) may represent at least a part of a digital twin of the physical entity of the chemical product. The digital twin may be a digital representation of the physical entity. The digital twin may hence represent a digital version of said physical entity. Once created, the digital twin may be used to represent the physical entity of the chemical product in a digital representation of a real- world system.

[0237] The decentral system may be used to gather chemical product data associated with chemical product(s) used to produce batteries as described in the context of FIG. 13A and FIG. 16. The chemical product data may correspond to chemical product data set(s) stored in assets DB 604. The chemical product data may be gathered by a downstream production stage with respect to the production stage producing the chemical product. The chemical product data may be gathered by the battery pack production stage, the battery production stage or the production stage producing the battery containing product.

[0238] The decentral system may include one or more decentral participants, such as a data consumer and a data provider. The data consumer and the data provider may be connected via a decentral network, such as a decentral peer-to-peer network (see for example FIG. 1 and FIG. 2). The data provider may provide data, such as chemical product data set(s), associated with a chemical product to data consumer. The data consumer may request chemical product data, such as the chemical product data set(s), from the data provider. The data provider may correspond to an entity producing chemical products, such as battery chemical products. The data consumer may correspond to an entity using the produced chemical product(s) and / or an entity performing the methods disclosed in FIG. 13A to FIG. 16. The data consumer may correspond to a downstream participant of the production chain with respect to the chemical product producer. The data provider may be associated with a data provider environment 808. The data consumer may be associated with a data consumer environment 802. The environments may include one or more node(s). The node(s) may be connected via peer-to-peer communication channels to allow data transfer between the nodes, as described in the context of FIG. 1 and FIG. 2. The decentral system may include more or less environments than illustrated in FIG. 8.

[0239] The participants of the decentral network may be associated with decentral participant identifiers. Each participant of the decentral network may be associated with one or more decentral participant identifier(s). The decentral participant identifier may comprise any identifier uniquely associated with a participant of the decentral network and / or with a production site of the participant of the decentral network. The decentral participant identifier may include letters and / or numbers. The decentral participant identifier may include one or more Universally Unique Identifier(s) (UUID(s)) and / or one or more Decentralized Identifier(s) (DID(s)). The decentral participant identifier may be associated with or may include a verifiable claim or credential. The verifiable claim may be issued by a central or decentral identity issuer making one or more claims about a subject, such as an entity being a trustworthy participant of the decentral network. For instance, the issuer may make a claim about a consumer (e.g. the entity operating data consuming network node(s)) or a provider (e.g. the entity operating data providing network node(s)) the decentral participant identifier is associated with. The verifiable claim may include those claim(s) as well as proof instructions to prove that claim(s) have not been tampered with and were indeed issued by the claims issuer. The verifiable claim may also include duration information metadata that defines a period of time that the verifiable claim is valid for use or that defines a specific number of times that the verifiable claim is authorized for use. The verifiable claim may also include a DID of the claims issuer and / or the subject, such as an entity. The verifiable claim may be signed by the claims issuer. The claims issuer may provide the verifiable claim to a claims holder, such as the entity, for presentation to any relying party that relies upon the veracity of those claims, such as a decentral data provider. The signature of the verifiable claim may be validated with a public key associated with the claims issuer to determine that the respective entity is a trusted entity within the decentral network. The verifiable credential may be presented by a decentral data consuming network node and may be used by a decentral data providing network node to verify that the decentral participant associated with the decentral data consuming network node is a trusted entity within the decentral network prior to providing access to data, such as chemical product data, hence ensuring that the chemical product data can be exchanged in a secure and controlled manner within the decentral network.

[0240] Data consumer environment 802 may include a consumer node 122 (e.g. decentral data consuming network node 122) and a consumer backend 804. Consumer backend 804 may include or correspond to the system illustrated in FIG. 13A and FIG. 13B. Consumer node 122 may be configured to communicate with consumer backend 804.

Consumer backend 804 may be configured to send a request for data to consumer node 122, for example as described in the context of FIG. 13A to FIG. 16. Consumer backend 804 may be configured to process chemical product data received from consumer node 122, for example as described in the context of FIG. 13A to FIG. 16.

[0241] Data consumer environment 802 may be associated with a participant of the battery ecosystem, such as the battery ecosystem illustrated in FIG. 1 and FIG. 2. For instance, data consumer environment 802 may be associated with a chemical product producer, such as chemical product user 106, receiving input material(s) and producing chemical product(s) using the input material(s).

[0242] Data consumer environment 802 may be associated with an entity performing the methods illustrated in FIG. 14 to FIG. 17. The entity performing such methods may be a participant of the battery ecosystem. The entity performing such methods may not be a participant of the battery ecosystem but may function as a service provider providing validated chemical product data for generation of battery passports. The service provider may gather chemical product data from various provider environment(s) associated with chemical product data of chemical products used to produce a given battery. The service provider may process the gathered chemical product data as described in the context of FIG. 13A to FIG. 17. The service provider may provide the processed chemical product data for generation of battery passports.

Provider node 118 may be configured to perform authentication and authorization step(s) prior to providing chemical product data, for example as described with reference to FIG. 9 later on. Provider node 118 may be coupled to data transfer service 602 configured to gather chemical product data set(s) from assets DB 604 in response to a request received from provider node 118 and to provide the gathered chemical product data set(s) to provider node 118.

[0244] FIG. 9 illustrates a flow chart of an example method for generating chemical product data set(s) associated with produced chemical product(s). The method illustrated in FIG. 9 may be implemented by the system illustrated in FIG. 6A to FIG. 7. The chemical product may be a battery chemical product, such as described in the context of FIG. 8. The chemical product may be used by one or more downstream participants of the battery ecosystem as input material to produce one or more batteries. The chemical product may be produced or producible by a production, such as illustrated in FIG. 7.

[0245] With reference to FIG. 7, the chemical product may be produced by a chemical production from one or more production input(s) through one or more production process(es) performed within the chemical production. The production input(s) may include chemical materials, such as inorganic chemical materials and / or organic chemical materials. The inorganic and / or organic chemical materials may be synthetic chemical materials. The input materials may be provided by upstream production stages with respect to the chemical product production stage. The chemical product may be produced via chemical process(es) and / or physical process(es) within the production. The physical process(es) may involve the use of chemical materials.

[0246] With reference to FIG. 12, data associated with the produced chemical product may be provided (see block 902). The data may be provided by a computing system connected to the system performing the method of FIG. 9, such as an asset generation system 646. The data may be provided by a user via a communication interface to the system performing the method of FIG. 9, such as an asset generation system 646.

Data associated with the chemical product may include digital chemical product identifier(s). The digital chemical product identifier(s) may include chemical product name, chemical product number, LOT number, batch number or a combination thereof.

[0247] With continued reference to FIG. 12, chemical product data may be gathered based on the provided data (see block 904). The chemical product data may be gathered from a data source layer, such as data source layer 620 described in the context of FIG. 6A and FIG. 6B. The chemical product data may be gathered from data source layer 620 based on digital chemical product identifier(s) included in the data provided in block 902. The chemical product data may be gathered by data gathering unit 622. The chemical product data may include chemical product identifier(s), property data associated with the chemical product, the chemical product name, the chemical product producer chemical product declaration data, chemical product safety data, emission data associated with the chemical product, recyclate content data associated with the chemical product, biobased content data associated with the chemical product, biodegradability data associated with the chemical product, production data associated with the chemical product, certificate of analysis data associated with the chemical product, certificate data associated with the chemical product, life cycle data associated with the chemical product, storage instruction data associated with the chemical product, assembly instructions associated with the chemical product and / or operating conditions associated with the chemical product as described in the context of FIG. 6A.

The one or more rule(s) may be associated with or derived from or generated based on a data model associated with the battery or the battery type. The battery may be produced from the chemical product by using the chemical product as input material within at least one production step of the production process of the battery. The production process of the battery may include one or more production steps. The production steps may be performed by one or more entities of the battery ecosystem. The chemical product may be used as input material within at least one of such production step.

[0249] With reference to FIG. 6B, FIG. 10 and FIG. 12, transforming the gathered chemical product data by the rule-based engine may include identifying one or more rule(s) applicable to the gathered chemical product data. The gathered chemical product data may be transformed by data transforming unit 624, The applicable rule(s) may be identified based on an identifier associated with each applicable rule matching or being related to a chemical product identifier included in the gathered chemical product data. The identifier associated with each applicable rule may include a chemical product identifier matching the chemical product identifier included in the gathered chemical product data. The identifier associated with each applicable rule may include a chemical product type identifier related to the chemical product identifier included in the gathered chemical product data. The chemical product type identifier related to the chemical product identifier included in the gathered chemical product data may be determined based on mapping data as described in the context of FIG. 6B.

[0250] With continued reference to FIG. 6B, FIG. 10 and FIG. 12, executable logic may be generated from the one or more applicable rule(s). The executable logic may be generated by data transforming unit 624. Executable logic may include machine code, interpretable code, bytecode, and / or code that runs on a virtual machine. The logic included in the applicable rule(s) may be encoded in the executable logic. The logic included in the applicable rule(s) may be mirrored in the executable logic. Upon finalizing the generation of the executable logic, data transforming unit 624 may sent a response to data gathering unit 622 indicating finalizing the generation of the executable logic. With continued reference to FIG. 6B, FIG. 10 and FIG. 12, a chemical product data set may be generated by transforming the gathered chemical product data by executing the generated executable logic by the rule-based engine subject to rule execution criteria. Data gathering unit 622 may sent a request to data transforming unit 624 to transform the chemical product data based on the executable logic generated for the applicable rule(s). Rule execution criteria may include rule execution order, exemptions and conditions. For instance, the rule designated in the condition is executed first as it triggers the execution or exemption action in the execution of the rule with which it is associated. The generated chemical product data set(s) may be provided from data transforming unit 624 to data provider unit 644.

[0251] It may be verified whether the gathered chemical product data could be transformed according to one or more applicable rule(s) (e.g. one or more rule(s) gathered from rule DB 612 based on the gathered chemical product data) (see block 908). Verification may be performed as described in the context of FIG. 6B. If the gathered chemical product data could be transformed according to the applicable rule(s), e.g. application of such rule(s) did not result in any error, the method may proceed to block 912. Otherwise message data may be generated and provided, for example as described in the context of FIG. 6B.

[0252] The generated chemical product data set may include at least a part of the gathered chemical product data. The chemical product data set may further include an asset identifier associated with the chemical product data set. The part of the chemical product data may be defined by the one or more applied rule(s). The part of the chemical product data may be in tabular data structure. The generated chemical product data set may include chemical product property data point(s), chemical product identifier data point(s), chemical product name data point(s), chemical product producer data point(s), chemical product declaration data point(s), chemical product safety data point(s), chemical product emission data point(s), chemical product recyclate content data point(s), chemical product biobased content data point(s), chemical product biodegradability data point(s), chemical product production data point(s), chemical product certificate of analysis data point(s), chemical product certificate data point(s), chemical product life cycle data point(s), chemical product storage instruction data point(s), chemical product assembly instruction data point(s) and / or chemical product operating condition data point(s).

[0253] The produced chemical product may be provided in association with the generated chemical product data set. The generated chemical product data set may be provided for access via a decentral network under control of the data owner of the chemical product data set. With reference to FIG. 12, this may include storing the generated chemical product data set in a data storage, such as assets DB 604, for example as described in the context of FIG. 6A. The data storage may be associated with the chemical product producer. The data storage may be associated with the production producing the chemical product. Access to the data storage may be controlled by the data owner, for example via the asset identifier included in the chemical product data set. With continued reference to FIG. 12, this may further include generating group access data and linking the group access data to the chemical product data set as described in the context of FIG. 6A. The group access data may be used to control access to the associated chemical product data set via the asset identifier, for example as described in the context of FIG. 14.

[0254] Use of rule(s) associated with a battery produced from such chemical product(s) allows to ensure that chemical product data point(s) required according to a data model, such as an aspect model, associated with the battery or battery type are contained in the chemical product data set, hence avoiding missing data point(s) during generation of a battery passport associated with the batter using said data model. The transformation allows to aggregate the gathered chemical product data into a given data data structure, such as a tabular data structure, without the use of complex ata models, hence facilitating generation and sharing of chemical product data set(s) within the product ecosystem. Such sharing may enable more efficient production and / or recycling processes based on the shared chemical product data, for instance chemical product composition data included in the shared chemical product data. The tabular data structure can be readily consumed via a decentral network by a consumer backend configured to validate the consumed data and to persist validated consumed data to data storages for generation of battery passports. Validation by the consumer side ensures that the battery passport contains all data required by a data model used to generate such passport, hence allowing to reduce the complexity associated with the chemical product data set generation at the provider side by avoiding the use of complex data models during generation of the chemical product data set(s). This may enable reliable sharing of chemical product data of chemical product(s) irrespective of the existence of data models for such chemical products since the rule(s) required to transform the gathered chemical product data may be readily derived from the data model associated with the battery or battery type.

[0255] FIG. 11 illustrates a flow chart of a further example method for generating chemical product data set(s) associated with chemical product(s) of a battery. The method illustrated in FIG. 11 may be implemented by the system illustrated in FIG. 6A to FIG. 7. The chemical product may be a battery chemical product described in the context of FIG. 8. The chemical product may be used by one or more downstream participants of the battery ecosystem as input material to produce one or more batteries. The chemical product may be produced by a production, such as illustrated in FIG. 7.

[0256] Incident data including non-validated chemical product data and data associated with rule(s) or a rule template resulting in the non-validation of such chemical product data may be received via a decentral network (see block 1102). The decentral network may be decentral network 134, 208 described in the context of FIG. 1 and FIG. 2. The incident data may be generated by a consumer environment, for example as described in the context of FIG. 17. The incident data may include the non-validated chemical product data point(s), the chemical product identifier and an indication indicating lack of validation. The indication may be a classifier, such as “validation failed”, “not validated”. The data associated with the rule(s) or rule template may include unstructured data, as described in the context of FIG. 6B. The data associated with the rule(s) or rule template may include executable logic generated from the rule(s) or rule template. With reference to FIG. 8, the incident data may be received by a data provider environment 808 associated with the non-validated chemical product data. The data provider environment 808 may include a decentral consumer node configured to consume data provided via the decentral network (not shown in FIG. 8). The data may be provided by a data provider node associated with data consumer environment 802 (not shown in FIG. 8). The incident data may be provided to the consumer node of data provider environment 808 as described in the context of FIG. 17.

[0257] With reference to FIG. 6A, the incident data received by consumer node of data provider environment 808 may be provided by the consumer node to asset generator service 606. The incident data may be provided via data transfer service 602 to asset generator service 606.

[0258] With continued reference to FIG. 6A and based on the received incident data, chemical product data associated with the chemical product may be gathered. The chemical product data may be gathered based on the chemical product identifier included in the incident data. The chemical product data may be gathered from a data source layer by asset generator service 606.

[0259] With continued reference to FIG. 6A and with reference to FIG. 6B, one or more rule(s) associated with the chemical product may be updated based on the received incident data. This may include generating one or more rule(s) or a rule template from the incident data. The generated rule(s) or rule template may be associated with the chemical product identifier or a corresponding chemical product type identifier. The generated rule(s) or the rule template may be stored in a database containing rule(s) and rule template(s), such as rule DB 612 associated with rule based engine 628.

[0260] With continued reference to FIG. 6A and FIG. 6B, an updated chemical product data set may be generated by transforming the gathered chemical product data using a rule-based engine including the updated rule(s). The updated rule(s) may be applicable to the gathered chemical product data, e.g. may be associated with a matching chemical product identifier or corresponding chemical product type identifier. The method may then proceed as described in the context of block 908 to 912 of FIG. 9.

[0261] Use of incident data to update rule(s) applicable to the chemical product data associated with the incident data may allow to generate updated chemical product data set(s) which may no longer fail validation using the rule(s) associated with the incident data. This may allow to provide - in response to a validation error occurring within a consumer environment validating such consumed chemical product data - updated chemical product data passing validation rule(s) which were not passed in the previous validation process. Use of such incident data to update rule(s) may hence allow to ensure that future chemical product data set(s) may not result in the same validation error. This may result in a more efficient validation and ensures that validated chemical product data is available for battery passport generation prior to providing such battery associated with the battery passport to a consumer. This allows the consumer, such as an end product user or recycler, to gather the passport data included in the battery passport associated with the battery and to use the gathered passport data to optimize and / or control production of battery containing products and / or to optimize and / or control recycling processes of battery containing products.

[0262] FIG. 13A illustrates a block diagram of an example system for validating chemical product data associated with chemical product(s) used to produce a battery. The chemical product(s) may be used as production input(s) in one or more process step(s) associated with the production of the battery. The process step(s) may be performed by one or more entities. The asset validation system 1342 may be configured to perform the methods described in the context of FIG. 14, FIG. 15 and FIG. 17. The system may be associated with a battery production. The system may be associated with a product production producing a battery containing product using the battery.

[0263] Asset validation system 1342 may include data transfer service 1302, stream storage system 1312 and data transforming unit 1304. Various databases, such as rule DB 1306, storage general 806 and storage application A 810 may be connected to data transforming unit 1304.

[0264] The asset validation system 1342 may be connected to a decentral data consuming node, such as node 122. The decentral data consuming node may be part of a decentral network, such as decentral network 134, 208 described in the context of FIG. 1 and FIG. 2. The decentral data consuming node 122 may be associated with a decentral participant. The decentral participant may be a participant of the product ecosystem associated with the product. The decentral participant may not be a service provider providing validated chemical product data for generation of battery passports, e.g. may not be a participant of the battery ecosystem. With reference to FIG. 8, decentral data consuming node 122 may be configured to request access to chemical product data set(s) at provider node(s) associated with such chemical product data set(s). The chemical product data set(s) may correspond to the chemical product data to be validated by the system. The request may include the chemical product identifier (e.g. asset identifier) associated with the chemical product data set(s) and a decentral participant identifier associated with the decentral participant operating consumer node 122. The request may be generated in response to data received from the system, for example received from data transfer service 1302. The data received from the system may include the asset identifier(s) and associated access data pointing to decentral provider node(s), such as provider node 118. The access data may include endpoint(s) associated with the decentral provider node(s), such as URI(s). The request may be generated per asset identifier and associated access data. The request received by the respective provider node(s) may be authenticated. Such authentication may be based on data related to an authentication mechanism. The authentication mechanism may be based on certificate(s) and / or token(s), for example a device certificate (X.509v3), a TLS connection certificate (X.509v3) and a ‘Dynamic Attribute Token’ (OAuth Access Token), associated with the respective decentral participant nodes, e.g. consumer node 122 and provider node 118. If authentication fails, no chemical product data set(s) may be provided by respective data provider(s).

[0265] Provider node(s) may initiate contract negotiations with consumer node 122. Contract negations may be initiated upon successful authentication. Provider node(s) may provide electronic contract(s) to consumer node 122. The electronic contract may include one or more authorization rule(s) associated with the chemical product identifier. The electronic contract may further include the endpoint(s) associated with the chemical product data set(s). The endpoint(s) may point to the dedicated storage storing the respective chemical product data set(s), such as assets DB 604. The electronic contract may be generated by the provider node(s) based on group access data and a contract template associated with the respective chemical product identifier(s). The system may automatically accept the provided electronic contract(s). The system may be configured to parse the provided electronic contract(s) to determine the authorization rule(s) associated with the chemical product data set(s) to be gathered. Consumer node 122 may provide data being indicative of the signature, such as a token, to respective provider node(s). If the electronic contract is not signed, consumer node 122 may likewise forward data being indicative of declining the contract to the respective provider node(s). Upon declining the contract, respective provider node(s) may terminate the connection and may not provide any chemical product data set(s). Signature of such electronic contracts generated from group access data and a contract template associated with respective chemical product identifier(s) ensures that the consumer node 122 and further systems, such as asset validation system 1342, handling the provided chemical product data are complying to at least one authorization rule included in the electronic contract associated with the chemical product data set(s). This may ensure that the chemical product data set(s) may be exchanged in a secure and controlled manner, hence avoiding access to chemical product data set(s) by unauthorized decentral network participants while allowing to provide the chemical product data set(s) to decentral network participants required to use such provided chemical product data set(s), for example to control and / or monitor production of the battery and / or to monitor and / or control recycling operations and / or to generate battery passports associated with the batteries.

[0266] With continued reference to FIG. 8, data providing node(s) may provide chemical product data set(s) associated with asset identifier(s) included in the request received from consumer node 122 upon signature of the electronic contract. The chemical product dataset(s) may be gathered from a dedicated storage, such as assets DB 604 as described in the context of FIG. 6A and FIG. 9.

[0267] Returning to FIG. 13A, consumer node 122 may provide the received chemical product data set(s) to data transfer service 1302. Data transfer service 1302 may be connected to stream storage system 1312. Stream storage system 1312 may be connected to data transforming unit 1304. Data transforming unit 1304 may be positioned upstream from data transfer service 1302. Chemical product data gathered via the decentral network may flow through data transfer service 1302 and stream storage system 1312 to data transforming unit 1304.

[0268] Data transfer service 1302 may be configured to receive chemical product data from consumer node 122. The chemical product data may represent a stream of data. Such a stream may be an ordered sequence of records received from consumer node 122 relatively continuously, i.e. not in accumulated batches or chunks. A record may for example comprise chemical product data associated with a given chemical product via a chemical product identifier. A record may be in a tabular representation. A record maybe in an object representation, e.g. using JSON, an XML document. A record may be defined as data that can be delivered continuously in small chunks or increments. The records may or may not be time-ordered. Data transfer service 1302 may be configured to generate data package(s) including the chemical product data received from consumer node 122. A data package may be generated by received chemical product data set. The data package may include further data, such as a time stamp, a date stamp, the chemical product identifier associated with the chemical product data, the decentral participant identifier associated with the provider node, location data pointing to the dedicated storage storing the chemical product data set or a combination thereof. The data package may represent a message or an event. The generated data package data may be provided to stream storage system 1312.

[0269] Stream storage system 1312 may be configured to store data packages received (e.g. pushed) from data transfer service 1302. The stream storage system 1312 may be configured to provide the stored data to data transforming unit 1304. The stream storage system 1312 may be configured to provide the stored data to data consuming unit 1308 of data transforming unit 1304. Stream storage system 1312 may comprise one or more persistent or non-persistent logs 1314, 1316. In this embodiment, stream storage system 1312 comprises two persistent or non-persistent logs 1314, 1316 (i.e. log 1 1314 and log 2 1316). Records stored in said logs may be ordered, for example by using IDs. This allows to identify a record within a specific log. A record may include a data package generated by data transfer service 1302.

[0270] Stream storage system 1312 may provide a streaming service or stream processing service between one or more streaming sources (e.g. data transfer service 1302) and one or more streaming sinks (e.g. log 1 1314 and log 2 1316). Stream storage system 1312 may act as a persistent or non-persistent stream sink for chemical product data received from consumer node 122. For example, open-source software systems such as Apache Kafka ("Kafka") or Azure Event Hubs may act as a persistent stream sink.

[0271] Stream storage system 1312 may be configured to pull chemical product data from data transfer service 1302. For instance, stream storage system 1312 may be configured to request chemical product data from data transfer service 1302 at regular time intervals.

[0272] Stream storage system 1312 may be configured to determine if the received or pulled chemical product data is already contained in the one or more persistent or non-persistent logs. If said chemical product data is already contained in the one or more persistent or non-persistent logs, stream storage system 1312 may not store the received or pulled chemical product data in said logs. If said chemical product data is not contained in one or more persistent or non-persistent logs or is an update, stream storage system 1312 may be configured to store the received or pulled chemical product data in the one or more persistent or non-persistent logs or to update chemical product data present in the persistent or non- persistent log(s) with the received or pulled updated chemical product data. This may avoid that the same chemical product data is stored multiple times in the persistent or non-persistent log(s), hence avoiding redundant validation operations on the chemical product data stored in stream storage system 1312. Data transforming unit 1304 may be connected to the stream storage system 1312. Data consuming unit 1308 of data transforming unit 1304 may be connected to stream storage system 1312. Data consuming unit 1308 may be connected to one or more persistent or non-persistent logs (e.g. in this embodiment in log 1 1314 and log 2 1316) of stream storage system 1312 to ingest and process chemical product data stored within the log(s). The stream storage system 1312 may be in a publisher-subscriber relationship with the data consuming unit 1308. For instance, data in one or more the logs(s) may be periodically read (e.g. pulled) by data consuming unit 1308. To avoid consumption of a data package stored in a log several times, such data package may be marked as consumed by stream storage system 1312. To avoid consumption of a data package stored in a log several times, an integer indicating the offset of the next data package to consume may be used. Such integer may be just one number for each persistent or non- persistent log. Such integer may be periodically checkpointed. Use of such an integer may allow data consuming unit 1308 to re-consume data packages by rewinding the integer to an old offset.

[0273] Data consuming unit 1308 may be connected to data validation unit 1310 of data transforming unit 1304. Data consuming unit 1308 may be configured to provide data packages gathered from stream storage system 1312 to data validation unit 1310 for validation of chemical product data included in said data packages. Data consuming unit 1308 may be configured to extract chemical product data from the data packages and provide the extracted chemical product identifier and chemical product data to data validation unit 1310. Data validation unit 1310 may be configured to validate chemical product data (e.g. data packages received from stream storage system 1312) based on one or more rule(s) retrieved from rule DB 1306, for example as described in the context of FIG. 13A. Validation may include applying one or more rule(s) retrieved from rule DB 1306 to the chemical product data. The chemical product data may be validated if at least a part of the applied rules are fulfilled. Applying the rule(s) to the chemical product data may include comparing the combination of chemical product identifier and location data to a database storing such combinations of chemical product identifier(s) and associated location data. Applying the rule(s) to the chemical product data may include comparing data point(s) present within one or more rule(s) to individual data point(s) present within the chemical product data to be validated. Applying the rule(s) to the chemical product data may include comparing data point combination(s) defined in the rule(s) to data point combination present within the chemical product data to be validated. Applying the rule(s) to chemical product data may include comparing the data defined in one or more rule(s) to the whole chemical product data to be validated. The one or more rule(s) may be associated with a battery produced from the chemical product(s). The one or more rule(s) may be associated with a data model of the battery or battery type. The data model may include a semantic description of the battery passport associated with the battery. The semantic description may include a semantic description of chemical product data and battery data. The semantic description may include the structure of at least a portion of the battery passport, and / or properties of the battery passport. The properties of the battery passport set may include data types. The properties of the battery passport set may include possible or allowable values and / or value ranges. The properties of the battery passport set may be a physical unit of parameter(s) described by values contained in the battery passport. The data type(s) and associated value(s) and / or value range(s) of chemical product data may be included in the one or more rule(s). This may allow to validate whether gathered chemical product data fulfils the data type(s) and associated value(s) and / or value range(s) required for chemical product data according to the data model. By validating the chemical product data against one or more rule(s) generated from the semantic model, it may be ensured that chemical product required by the data model is indeed included in the gathered chemical product data, allowing to ensure that battery passport(s) generated from such validated chemical product data include all required chemical product data. Validation of gathered chemical product data on data point level may allow to reliably perform the validation irrespective of the data structure of the chemical product data. This may allow, in turn, to generate the chemical product data without having to use complex data models. Instead, chemical product data may be generated in a tabular representation by the data providers and may be used by data validation unit 1310 for validation of data point(s) included in the chemical product data. The one or more rule(s) may define one for more chemical product identifier data point(s), chemical product property data point(s), chemical product name data point(s), chemical product producer data point(s), chemical product declaration data point(s), chemical product safety data point(s), chemical product emission data point(s), chemical product recyclate content data point(s), chemical product biobased content data point(s), chemical product biodegradability data point(s), chemical product production data point(s), chemical product certificate of analysis data point(s), chemical product certificate data point(s), chemical product life cycle data point(s), chemical product storage instruction data point(s), chemical product assembly instruction data point(s) and / or chemical product operating condition data point(s). The rule may define data point(s) per data category. The rule may define data point(s) for at least two different data categories. A data category may signify property data, declaration data, safety data, emission data, recyclate content data, biobased content data, biodegradability data, production data, certificate of analysis data, certificate data, storage instruction data, assembly instruction data or operating condition data.

[0274] By validating the chemical product data against one or more rule(s) generated from the data model, it may be ensured that chemical product data required by the data model is indeed included in the gathered chemical product data, allowing to ensure that battery passport(s) generated from such validated chemical product data include all required chemical product data. Validation of gathered chemical product data on data point level may allow to reliably perform the validation irrespective of the data structure of the chemical product data. This may allow, in turn, to generate the chemical product data without having to use complex data models. Instead, chemical product data set(s) may be generated in a tabular representation by the data providers and may be used by data validation unit 1310 for validation of data point(s) included in the chemical product data set(s) received as chemical product data by the data consumer side.

[0275] The validated chemical product data generated by data validation unit 1310 may include one or more validated chemical product property data point(s), validated chemical product identifier(s), validated chemical product name(s), validated chemical product producer data point(s), validated chemical product declaration data point(s), validated chemical product safety data point(s), validated chemical product emission data point(s), validated chemical product recyclate content data point(s), validated chemical product biobased content data point(s), validated chemical product biodegradability data point(s), validated chemical product production data point(s), validated chemical product certificate of analysis data point(s), validated chemical product certificate data point(s), validated chemical product life cycle data point(s), validated chemical product storage instruction data point(s), validated chemical product assembly instruction data point(s) and / or validated chemical product operating condition data point(s).

[0276] Data validation unit 1310 may further be configured to determine the storage location to which the validated chemical product is to be persisted. The storage location may be determined based on mapping data including a mapping between chemical product identifier(s) and associated storage location data. The storage location data may include endpoint(s) associated with said storage location(s). The storage location(s) may be identified by way of storage location identifier(s) included in the storage location data. Such identifier(s) may be used to gather endpoint(s) associated with such storage location(s). The mapping data may include a first mapping between chemical product identifier and chemical product type identifier and a second mapping between chemical product type identifier and associated storage location data. The mapping data may be stored in a database connected to data validation unit 1310 (not shown). Determining the storage location of validated chemical product data may allow to persist validated chemical product data in storage locations associated with given applications or systems(s). For instance, the validated chemical product data associated with a given battery may be persisted in a storage location associated with a given application processing such validated chemical product data. Processing may, for example include generation of battery passport(s) using such validated chemical product data. Validated chemical product data which may not be mapped to a given application may be persisted in a general storage, such as storage general 806.

[0277] Data validation unit 1310 may further be configured to provide the validated chemical product data to the determined storage location, such as general storage general 806 or storage application A 810, for storage.

[0278] The asset validation system 1342 may further include incident data generator 1344. Incident data generator 1344 may be configured to generate incident data based on non-validated chemical product data stored in a database, such as storage general 806. The non-validated chemical product data may be associated with a classifier indicating non-compliance with one or more applied rule(s). The classifier may include “not validated”, “not valid”, “validation failed” or “failed”. The classifier may be associated with each data point which could not be validated upon application of the one or more rule(s). Each data point which could not be validated may be associated with a respective chemical product identifier. Each data point which could not be validated may be associated with rule data indicating the rule that resulted in non-validation of the respective data point. The rule data may include the rule. The rule data may include the executable logic generated from the rule, for example as described in the context of FIG. 13B. Incident data generator 1344 may be configured to gather data point(s) associated with the classifier per chemical product identifier. Incident data generator 1344 may query the database for chemical product data associated with the classifier. Incident data generator 1344 may assemble gathered chemical product data into incident data based on the chemical product identifier associated with the gathered chemical product data. Incident data generator 1344 may provide the generated incident data to data transfer service 1302. Data transfer service 1302 may be configured to determine the provider node having provided the non-validated incident data. Data transfer service 1302 may be configured to initiate a transfer of the incident data to the determined node associated with asset generator system 606 generating the non-validated chemical product data set via consumer node 122. The incident data may be provided to the node, such as provider node 118, using an endpoint of such node configured to receive data from other nodes of the decentral network. The endpoint may be provided by such node to data transfer service 1302 or a backend connected to data transfer service 1302. The endpoint may be stored in a ledger interrelating consumer node(s) with respective endpoints used for pushing incident data to such consumer nodes. The consumer node(s) may be identified by decentral participant identifier(s). Generation and provision of incident data associated with non-validated data point(s) may allow the data provider providing such non-validated data point(s) to generated updated chemical product data, for example as described in the context of FIG. 11 and to provide the updated chemical product data set. Hence, the use of incident data may ensure that non-validated chemical product data point(s) can be corrected by respective data providers such that the updated chemical product data set(s) generated by the asset generator service 606 associated with node 118 pass(es) the validation. This may result in efficient and reliable generation of validated chemical product data required to generate battery passports and hence also in reliable generation of battery passports. The battery passports may allow to improve and / or control production of battery containing products and / or recycling processes of battery containing products or batteries based on passport data contained in the battery passports.

[0279] FIG. 13B illustrates a diagram showing an example of validating chemical product data associated with chemical product(s) used to produce a battery using a rule-based engine. The chemical product data may be gathered via a decentral network as described in the context of FIG. 8. The gathered chemical product data may correspond to chemical product data set(s) stored in a dedicated storage of a data provider environment, such as data provider environment 808 described in the context of FIG. 8.

[0280] Data validation unit 1320 may include rule based engine 1322. The rule based engine 1322 may operate on individual data point(s), multiple data point(s) and / or the gathered chemical product I data. The rule based engine 1322 may operate on data gathered per chemical product identifier individually. This allows to validate chemical product data per chemical product, hence allowing a more granular validation of the chemical product data. Rule based engine 628 may receive a request to validate gathered chemical product data. The request may contain at least a part of the gathered chemical product data. Data packages (e.g. messages or events) may be consumed from one or more log(s) of stream storage system 1312 (see operation 1338) by data consuming unit 1308 as described in the context of FIG. 13A. The consumed data packages may be extracted by data consuming unit 1308 (see operation 1346). The extracted chemical product identifier may be provided to rule based engine 1322. The rule based engine 1322 may have access to one or more rule(s). The rule based engine 1322 may include one or more rule(s). The one or more rule(s) may be present within a rule template. The one or more rule(s) and / or the rule template(s) may be stored in a data storage, such as rule DB 1318. The one or more rule(s) or rule template(s) may be provided to rule DB 1318 by a user. The one or more rule(s) may correspond to unstructured data associated with validation operation(s). The rule template(s) may include unstructured data associated with instructions related to validation operation(s). The one or more rule(s) or the rule template may be included in a file provided by the user. The one or more rule(s) or the rule template(s) may be associated with chemical product type identifier(s) and / or chemical product identifier(s). Rule based engine 1322 may generate a request to obtain one or more rule(s) from rule DB 1318. The request may contain the respective chemical product identifier(s).

[0281] One or more rule(s) associated with the chemical product data to be validated (e.g. one or more applicable rule(s)) may be provided to rule based engine 1322 in response to the request. The one or more rule(s) may define data point(s) and / or combination(s) of data point(s) to be present within the consumed chemical product data, e.g. to be present within a consumed chemical product data set. The one or more rule(s) may be associated with batteries produced from the chemical product associated with the chemical product data to be validated. The one or more rule(s) may be associated with or derived from or generated based on a data model of the battery or battery type. Hence, the one or more rule(s) may ensure that data point(s) associated with chemical product(s) and being required according to the data model may be included in the consumed chemical product data. The one or more rule(s) may be defined by the mandatory chemical product data point(s) present within the data model. The one or more rule(s) may be generated based on the mandatory chemical product data point(s) present within or defined by the data model. This may ensure that chemical product data required by the data model is included in the consumed chemical product data. The one or more rule(s) may define one for more chemical product property data point(s), chemical product identifier data point(s), chemical product name data point(s), chemical product producer data point(s), chemical product declaration data point(s), chemical product safety data point(s), chemical product emission data point(s), chemical product recyclate content data point(s), chemical product biobased content data point(s), chemical product biodegradability data point(s), chemical product production data point(s), chemical product certificate of analysis data point(s), chemical product certificate data point(s), chemical product life cycle data point(s), chemical product storage instruction data point(s), chemical product assembly instruction data point(s) and / or chemical product operating condition data point(s). The rule may define data point(s) per data category. The rule may define data point(s) for at least two different data categories. A data category may signify property data, declaration data, safety data, emission data, recyclate content data, biobased content data, biodegradability data, production data, certificate of analysis data, certificate data, storage instruction data, assembly instruction data or operating condition data. The one or more rule(s) may be associated with chemical product identifier(s) and / or chemical product type identifier(s). A mapping table may be used to map chemical product identifier(s) to corresponding chemical product type identifier(s). The chemical product type identifier(s) may be associated with chemical product type(s). The mapping table may be stored in a separate database (not shown). Rule based engine 1322 may be configured to gather chemical product type identifier(s) based on determined chemical product identifier((s) and to request rule(s) based on the gathered chemical product type identifier(s). This may allow to gather rule(s) associated with chemical product type identifier(s) based on chemical product identifier(s), hence avoiding generation of rule(s) per chemical product identifier and reducing the number of rule(s) that need to be generated, stored and maintained in rule DB 1318.

[0282] Rule based engine 1322 may be configured to initialize the rule engine (see operation 1326). Initialization of the rule engine may include generating rule data executable by a processor included in rule based engine 1322. The rule data may include or correspond to executable logic. This may allow to transform rule(s) or rule template(s) present in unstructured data form into code that can be executed by the processor. Execution of the code may result in applying the executable rule data to the extracted chemical product data (see operation 1328) to validate the consumed chemical product data according to the obtained rule(s). Execution of the logic may result in matching consumed chemical product data to data point(s) and / or combination(s) of data point(s) included in the executable logic, evaluating the data point(s) or combination(s) of data point(s) with matched chemical product data and generating validation result data based on the evaluation results. The validation result data may include a classifier and associated validated or non-validated chemical product data point(s). The classifier may be a binary classifier discriminating validated and non-validated i chemical product data. Consumed chemical product data point(s) may be considered validated if one or more rule(s) applied by rule based engine 1322 are fulfilled. Applying the rule(s) to the consumed chemical product data may include comparing individual data point(s) present within the rule(s) to individual data point(s) present within the chemical product data to be validated to determine whether the chemical product data to be validated includes individual data point(s) required by such rule(s). Applying the rule(s) to the consumed chemical product data may include comparing data point combination(s) defined in the rule(s) to data point combination present within the chemical product data to be validated to determine whether the chemical product data contains data point combinations required by such rule(s). Applying the rule(s) to the consumed chemical product data may include comparing the data defined in the rule(s) to the whole chemical product data set to be validated to determine whether the chemical product data set contains all data required by such rule(s). Operations performed by rule based engine 1322 may be determined by rule(s) gathered from rule DB 1318. For instance, rule(s) gathered from rule DB 1318 may determine whether rule based engine 1322 operates on individual data point(s) and / or multiple data point(s) of the consumed chemical product data and / or the whole chemical product data.

[0283] Rule based engine 1322 may be configured to determine whether the consumed chemical product data fulfills one or more applied rule(s) (see operation 1330). Consumed chemical product data may not be validated or only partially validated (e.g. validation may result in at least one error associated with applying one or more obtained rule(s) to the consumed chemical product data) if the consumed chemical product does not include data point(s) required according to one or more obtained rule(s). Rule based engine 1322 may indicate to data validation unit 1320 successful validation of the consumed chemical product data responsive to the determination that the consumed chemical product data is successfully validated (e.g. fulfils one or more obtained rule(s)). In response to receiving that indication, data validation unit 1320 may determine the target data storage where the validated chemical product data is to be persisted (see operation 1340). The target data storage may be determined as described in the context of FIG. 13A. If data validation unit 1320 determines that the validated chemical product data is not associated with a given application, data validation unit 1320 may provide the validated chemical product data to a storage not being associated with any application processing the validated chemical product data, such as storage general 806. If data validation unit 1320 determines that the validated chemical product data is associated with a given application, data validation unit 1320 may provide the validated chemical product data to a storage being associated with such application processing the validated chemical product data stored therein, for example by generating battery passports.

[0284] If at least a part of the consumed chemical product data could not be validated, rule based engine 1322 may indicate to data validation unit 1320 that at least a part of the consumed chemical product data could not be validated. In response to receiving the indication, data validation unit 1320 may generate message data (operation 1332). The message data may indicate that at least part of the consumed chemical product data could not be validated. The message data may include an indication which data point(s) of the consumed chemical product data could not be validated. The message data may be provided to a display device configured to display data received from data validation unit 1320. The display device may comprise a graphical user interface 1334. The display device may display the message in response to receiving message data from rule based engine 1322. This allows to trigger correction or updating of non-validated data points, for example by generating incident data as described in the context of FIG. 13A.

[0285] Rule based engine 1322 may be configured to provide non-validated chemical product data to a storage not being associated with any application processing the validated chemical product data, such as storage general 806. The non-validated chemical product data may be provided to such storage along with a classifier classifying such chemical product data as non-validated. The non-validated chemical product may be provided to such storage along with the classifier and rule data indicating the applied rule(s) resulting in non-validation of at least a part of the chemical product data.

[0286] FIG. 14 illustrates a flow chart of an example method for validating chemical product data associated with chemical product(s) used to produce a battery. The battery may be used to produce a battery containing product. The method illustrated in FIG. 14 may be implemented by the system illustrated in FIG. 13A and FIG. 13B. The chemical product(s) may be used as production input(s) in one or more process step(s) associated with the production of the battery. The process step(s) may be performed by one or more entities. The battery may be produced by a battery production from the chemical product based on one or more process(es) performed within the production. The process(es) may include assembly process(es).

[0287] The battery may be produced from the chemical product(s) by a battery production. The battery may be produced from the chemical product(s) by one or more processes performed within the battery production. The processes may include assembly processes. The battery may be produced by a downstream production stage with respect to the production stage supplying the chemical product(s). The battery may be used by a downstream production stage to produce a battery containing product. The battery containing product may be produced from the battery by one or more processes performed within the battery production. The processes may include assembly processes.

[0288] Battery data associated with the battery may be provided. The battery data may include battery identifier(s) associated with the battery and chemical product identifier(s) associated with chemical product(s) used to produce the battery may be provided (see block 1402). The identifier(s) associated with the chemical product may be asset identifiers associated with or included in the chemical product data. The battery data may be provided from one or more database(s) storing such battery data. The one or more database(s) may be associated with the production producing the battery or the production producing the battery containing product. The battery data may be provided by an entity producing the battery to the entity performing the method illustrated in FIG. 14. The battery data may further include battery property data. The battery property data may include at least one measured chemical and / or physical property of the battery and / or at least one chemical and / or physical property determined from collected data associated with the production of the battery. At least a part of the battery data may be stored in one or more databases. The one or more database(s) may be determined based on mapping data. The mapping data may map battery identifier(s) to applications and associated databases. The mapping data may map battery identifier(s) to battery type identifier(s) and associated applications and databases.

[0289] Chemical product data may be gathered via a decentral network based on the chemical product identifier(s) included in the provided battery data (see block 1404). The decentral network may be decentral network 134, 208 described in the context of FIG. 1 and FIG. 2. The chemical product data may be gathered by a decentral data consuming node, such as consumer node 122, from decentral data providing node(s), such as provider node 118, associated with the respective chemical product data as described in the context of FIG. 8. With reference to FIG. 15, gathering chemical product data may include determining decentral data providing node(s) associated with the chemical product data matching the chemical product identifier(s) (e.g. chemical product data associated with the provided chemical product identifier(s)). Determining such provider node(s) may include providing candidate decentral provider nodes associated with chemical product data of chemical product(s) used to produce the battery. The candidate provider node(s) may be provided by providing a database storing candidate provider node data associated with chemical product identifier(s) matching chemical product identifier(s) of chemical product data set(s) associated with such candidate provider node(s) (e.g. accessible via said candidate provider node(s)). The candidate provider node data may include access data associated with the candidate provider node(s). The candidate provider node data may further include candidate provider node identifier(s) and / or decentral participant identifier(s) associated with the candidate provider node(s). The database may include mapping data mapping candidate provider node data to chemical product identifier(s) associated with chemical product data provided by candidate provider nodes associated with the candidate provider node data. The database may be updated upon receiving new candidate provider data and associated chemical product identifier(s). Use of such mapping data allows to efficiently determine target provider node(s) associated with the required chemical product data, hence resulting in a reduced latency associated with the gathering of the chemical product data. This may ensure, that the chemical product data may be validated and the validated chemical product data may be processed, for example by generating battery passports, prior to providing the battery associated with the battery passport or a product including the battery associated with the battery passport to a consumer, such as an end product user. Efficient generation of battery passports may avoid storage of produced batteries or battery containing product(s) prior to providing them to consumers due to the absence of associated battery passports which may need to be generated from a regulatory standpoint prior to providing the associated battery or battery containing product to a consumer.

[0290] With continued reference to FIG. 15, access data for target decentral provider nodes associated with the chemical product data may be determined based on the provided chemical product identifier(s). Target provider nodes may be identified by matching the provided chemical product identifier(s) to chemical product identifier(s) stored in the mapping data. The candidate provider node data associated with matching chemical product identifier(s) may be gathered from such database as target provider node data. The gathered target provider node data may be parsed to determine access data associated with target decentral provider node(s) (e.g. provider node(s) associated with dedicated storage(s) storing chemical product data associated with provided chemical product identifier(s)).

[0291] With continued reference to FIG. 15, access to chemical product data associated with the provided asset identifier(s) may be requested from target data provider node(s) associated with the determined access data. Access to chemical product data may be requested as described in the context of FIG. 13A. The chemical product data may be provided by the target provider node(s) in response to such a request, for example as described in the context of FIG. 8.

[0292] Returning to FIG. 14 and with reference to FIG. 13A and FIG. 16, the gathered chemical product data may be provided to a stream storage system, such as stream storage system 1312 described in the context of FIG. 13A. A data consumer, such as data consuming unit 1308 described in the context of FIG. 13A may consume the gathered chemical product data from the stream storage system. The consumer may extract chemical product identifier(s) and chemical product data from the consumed data package(s). The stream storage system may hence serve as a chemical product data sink and allows to compensate the asynchronous gathering of the chemical product data from the decentral network. Gathered chemical product data set(s) may be provided as messages or events to stream storage system. Stream storage system may publish such received message(s) or event(s), e.g. may persist the received message(s) or event(s) in a persistent or non-persistent log, for example as described in the context of FIG. 13A. The messages or events may be generated by data transfer service 1302, for example as described in the context of FIG. 13A. The data consumer may listen to published messages and / or events (see FIG. 13A) and may consume new messages and / or events. This may ensure that validation may be performed per chemical product data set and avoids validating a given chemical product data set multiple times.

[0293] With continued reference to FIG. 13A and FIG. 16 and with further reference to FIG. 13B, at least a part of the gathered chemical product data may be validated by using a rule-based engine including one or more rule(s) associated with the battery. The chemical product data may be validated by data validation unit 1310. The applicable rule(s) may be identified based on an identifier associated with each applicable rule matching or being related to a chemical product identifier included in the extracted chemical product data. The identifier associated with each applicable rule may include a chemical product identifier matching the chemical product identifier included in the extracted chemical product data. The identifier associated with each applicable rule may include a chemical product type identifier related to the chemical product identifier included in the extracted chemical product data. The chemical product type identifier related to the chemical product identifier included in the extracted chemical product data may be determined based on mapping data as described in the context of FIG. 13B.

[0294] With continued reference to FIG. 13B and FIG. 16, executable logic may be generated from the one or more applicable rule(s). The executable logic may be generated by data validation unit 1310. Executable logic may include machine code, interpretable code, bytecode, and / or code that runs on a virtual machine. The logic included in the applicable rule(s) may be encoded in the executable logic. The logic included in the applicable rule(s) may be mirrored in the executable logic. Upon finalizing the generation of the executable logic, data validation unit 1310 may sent a response to data consuming unit 1308 indicating finalizing the generation of the executable logic.

[0295] With continued reference to FIG. 13B and FIG. 16, extracted chemical product data may be provided to data validation unit 1310 by data consuming unit 1308 in response to receiving an indication that the generation of the executable logic has been finalized. The extracted chemical product data may be validated by executing the generated executable logic. The executable logic may be subject to rule execution criteria. Data consuming unit 1308 may sent a request to data validation unit 1310 to transform the extracted chemical product based on the executable logic generated for the applicable rule(s). Rule execution criteria may include rule execution order, exemptions and conditions. Validation data including the result of the validation may be generated by the rule engine. The validation data may include the chemical product data points subject to the validation process and associated classifiers. The classifiers may indicate whether the respective chemical product data point passed or failed the validation process. The validation data may further include rule data associated with data point(s) for which validation failed. The rule data may indicate the applied rule(s) which resulted in a fail of the validation of such data point.

[0296] Returning to FIG. 14 and with continued reference to FIG. 16, it may be verified whether the extracted chemical product data could be validated according to one or more applicable rule(s) (e.g. one or more rule(s) gathered from rule DB 1318 based on the gathered chemical product data (see block 1408). Validation may be performed as described in the context of FIG. 13B. If the extracted chemical product data could be validated according to the applicable rule(s), e.g. application of such rule(s) did not result in any error, the method may proceed to block 1418. If only a part of the extracted chemical product data could be validated, the method may proceed to block 1414. If the extracted chemical product data could not be validated, the method may proceed to block 1410.

[0297] In block 1410, message data may be generated, for example as described in the context of FIG. 13B. The validation data including the non-validated chemical product data may be provided to a storage location, for example as described in the context of FIG. 13B. The validation data including the nonvalidated chemical product data may be used to generate incident data, for example das described in the context of FIG. 13A and FIG. 17.

[0298] In block 1414, message data may be generated, for example as described in the context of FIG. 13B. In block 1416, validation data including the non-validated chemical product data may be provided to a storage location as previously described.

[0299] Validated chemical product data may be linked to at least one of the battery identifiers (see block 1418). This may allow to gather the validated chemical product data based on at least one of the battery identifiers, for example upon generating the battery passports.

[0300] With continued reference to FIG. 13A and FIG. 13B, the validated data may be provided for generating battery passport(s). Providing the validated data may include determining storage location(s) for at least a part of the validated chemical product data. The storage location(s) may be determined based on chemical product identifier(s) associated with the validated chemical product data (see block 1420). The chemical product identifier(s) may be included in the validated chemical product data. The storage location(s) may be determined as described in the context of FIG. 13A and FIG. 13B. Providing the validated chemical product data to a database used by a defined application to process the validated chemical product data may allow to sort the validated chemical product data according to applications processing or consuming the validated chemical product data. This may improve security since unauthorized data access by applications not processing the validated chemical product data stored in such database is avoided. Moreover, this may reduce latency to generate battery passports since the amount of data stored within a particular database is reduced by selectively providing validated chemical product data to be processed by a given application to database(s) associated with such application. With continued reference to FIG. 16, at least a part of the validated chemical product data linked to at least one of the battery identifiers may be provided to determined storage location(s) for generating battery passport(s) associated with the battery including at least a part of the validated chemical product data (see block 1422). The validated chemical product data provided to such storage location(s) may be persisted in such storage location(s).

[0301] By gathering chemical product data directly from respective data provider nodes associated with such chemical product data, e.g. by avoiding a query to the decentral network to locate the data provider node(s) associated with the desired chemical product data, the chemical product data may be gathered via the decentral network reliably and quickly. By validating the gathered chemical product data by a rulebased engine including one or more rule(s) associated with the battery or battery type, such as rule(s) associated with a data model of the battery or battery type, battery passports may be reliably generated from such validated chemical product data since validation allows to ensure that all chemical product data points required according to the semantic model used to generate the battery passport are available (e.g. are stored within a dedicated storage). By validating the gathered chemical product data at the consumer side, the chemical product data can be directly gathered from the provider side without requiring the provider side to provide chemical product data adhering to a defined data structure. Hence, the provider side may not be required to generate the chemical product data gathered by the consumer side by using complex data models resulting in highly defined chemical product data points. Instead, chemical product data may be provided as a tabular representation to the consumer side and such chemical product data may be validated on data point level to ensure that the gathered chemical product data includes all data point(s) mandatory with respect to a data model used to generate battery passports from the validated chemical product data. By validating the chemical product data on consumer side, the effort to generate and provide chemical product data at the provider side is greatly reduced while maintaining security, hence resulting in reliable, quick and secure sharing of chemical product data required to generate battery passports. This in turn may allow to generate battery passports associated with batteries produced from such chemical product in a reliable and efficient way, ensuring a high data quality of the battery passport as well as that such battery passports are available upon providing the battery or battery containing product to a consumer without having to store the battery or battery containing product until generation of the associated battery passport is completed. The high data quality of the battery passport may allow consumers of the associated battery to control and / or monitor production processes using the battery and / or recycling processes involving battery containing endproducts and / or the battery, in a more reliable and / or efficient way. In addition, this setup allows to gather chemical product data for various chemical product(s) from various data provider nodes simultaneously while ensuring that gathered chemical product data is correctly validated and persisted to a database associated with an application consuming the validated chemical product data persisted in such database. FIG. 17 illustrates a flow chart of a further example method for validating chemical product data associated with chemical product(s) used to produce a battery. The method illustrated in FIG. 17 may be implemented by the system illustrated in FIG. 13A and FIG. 13B. The chemical product(s) may be used as production input(s) in one or more process step(s) associated with the production of the battery. The process step(s) may be performed by one or more entities.

[0302] Incident data including non-validated chemical product data and data associated with rule(s) or a rule template resulting in the non-validation of such chemical product data may be generated (see block 1702). The incident data may be generated by incident data generator 1344, for example as described in the context of FIG. 13A.

[0303] The generated incident data may be provided via a decentral network to the decentral data provider associated with the non-validated chemical product data. The decentral data provider may be determined based on the chemical product identifier included in the generated incident data as described in the context of FIG. 15 using mapping data including candidate provider node data and associated chemical product identifier. For instance, the chemical product identifier included in the incident data may be matched to chemical product identifier(s) included in the mapping data to determine associate provider node data. The associated provider node data may be parsed to determine the access data associated with such provider node. The access data may be used to provide the incident data to the provider node associated with the access data.

[0304] In response to receiving the incident data, a backend system associated with the provider node receiving the incident data, such as asset generation system 646, may generate updated chemical product data set, for example as described in the context of FIG. 11. The updated chemical product data may be provided to the consumer node providing the incident data used to generate the updated chemical product data. The updated chemical product data may be provided to the consumer node by pushing such data to the consumer node without receiving a request for such data, for example as described in the context of FIG. 13A. This may allow to provide the updated chemical product data after generation of such chemical product data, hence reducing a delay in transfer of the updated chemical product data to the consumer node and facilitating timely validation of the updated chemical product data and generation of the battery passport using the updated and successfully validated chemical product data. This may avoid that battery passports may not be generated due to lack of validated chemical product data and may ensure that battery or battery providing product provided to the consumer, such as an end product user or recycler, is associated with a battery passport allowing the consumer to gather passport data included in the battery passport and to use the passport data to control and / or optimize further production processes using the battery and / or recycling processes of battery containing end-products and / or the battery.

[0305] The updated chemical product data may be validated, for example as described in the context of FIG. 14. The present disclosure has been described in conjunction with preferred embodiments and examples as well. However, other variations can be understood and effected by those persons skilled in the art and practicing the claimed invention, from the studies of the drawings, this disclosure and the claims.
