[0002] OFD (Open Fixed-layout Document) is one of my country's electronic document standards, serving as the standard for electronic document exchange and storage. It can be used to represent fixed-layout documents with specific formatting requirements. For example, when issuing electronic tax invoices, the Ministry of Finance pilots enterprises using OFD files to generate corresponding electronic voucher files. These electronic vouchers can serve as the basis for enterprise reimbursement, accounting, and archiving, and are currently widely used in Zhejiang Province.

[0003] Current technology only supports the parsing and encapsulation of OFD files, and cannot generate custom OFD layout styles. Furthermore, existing technology lacks a standard for storing structured data, which is not conducive to the subsequent use of OFD files.

[0004] In summary, how to reduce the complex technical problems in the OFD file generation process and provide a standard solution for extracting structured data from OFD files is a problem that needs to be solved. Summary of the Invention

[0014] Optionally, adjusting the object data according to a preset adjustment rule includes:

[0015] The target font size of the object data is determined based on the spatial width of the target OFD board template, and it is determined whether the target font size is less than a preset font size threshold.

[0016] If the target font size is smaller than the preset font size threshold, the object data will be dynamically wrapped according to the preset dynamic line wrapping rules to convert it into multiple lines for display.

[0017] If the target font size is not less than the preset font size threshold, the object data will be displayed based on the target font size.

[0018] Optionally, writing the object data into the target OFD structured data template includes:

[0024] Optionally, before obtaining the object data uploaded by the user terminal, the method further includes:

[0025] Draw corresponding OFD templates according to different business types, and add fields and labels to the OFD templates;

[0026] Based on the OFD template, a corresponding OFD structured data template is generated, and the OFD template and the OFD structured data template are imported into the software development kit.

[0027] Optionally, the OFD file generation method further includes:

Finally, the object data is written into the target OFD layout template and the target OFD structured data template respectively, and the generated results are merged and packaged to obtain the OFD file. Therefore, for SSD users, after determining the target template information in the SSD, they only need to write the object data uploaded by the user terminal into the OFD layout template and the OFD standard data structure template obtained after parsing the XML file to complete the entire OFD file generation. This technical solution reduces the complexity of the OFD file generation process, provides a unified structured data standard, and enables data extraction without relying on other devices, effectively improving the use and promotion of OFD files in fields such as electronic invoices and bank documents.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Current technology only supports the parsing and encapsulation of OFD files, and cannot generate custom OFD layout styles. Furthermore, existing technology lacks a standard for storing structured data, which is not conducive to the subsequent use of OFD files.

[0047] To this end, this application provides an OFD file generation scheme that can reduce the complex technical problems in the OFD file generation process and provide a standard scheme for subsequent extraction of structured data from OFD files.

[0048] This invention discloses a method for generating OFD files, see [link to documentation]. Figure 1 As shown, applied to a software development kit, the method includes:

[0049] Step S11: Obtain object data uploaded by the user terminal.

[0050] In this embodiment of the application, during the process of generating the OFD file, the object data uploaded by the user terminal is first obtained. This object data is metadata, which is the metadata input by the user terminal when generating the OFD file for the current service.

[0051] Step S12: Determine the target template information in the software development kit, and parse the Extensible Markup Language (XML) file in the target template information to obtain the target OFD board template and the target OFD structured data template.

[0052] In this embodiment, it is applied to a Software Development Kit (SDK). An SDK is a software development kit written in the Java programming language that generates OFD files and structured data. It requires a Java container to run; generally, technical personnel need to set up a Java project and then import the SDK into the tool for secondary development.

[0053] It should be noted that the software development kit (SDK) includes pre-built templates for various types of electronic documents, such as electronic invoices, bank statements, and flight itineraries, along with corresponding standard structured data templates. Before using the SSD, different OFD template files are designed and drawn according to different business types, and then imported into the SSD. Corresponding OFD structured data template files are then generated and imported into the SSD. Specifically, corresponding OFD templates are drawn according to different business types, and fields and labels are added to these templates. Based on these OFD templates, corresponding OFD structured data templates are generated, and both the OFD templates and the OFD structured data templates are imported into the SSD.

[0054] In this embodiment, since different templates may be used when processing related business, the target template information in the software development kit (SDK) is determined. For example, when issuing invoices, different invoice types often correspond to different OFD templates. If a VAT electronic invoice is to be generated, the corresponding OFD template is a VAT electronic invoice template. Therefore, the corresponding template file information is initialized first; the template file information is initialized according to the required template type to determine the target template information. It should be noted that when initializing the corresponding template information, only the template format information needs to be initialized; the structured data template can be directly called.

[0055] Furthermore, by parsing the Extensible Markup Language (XML) file in the target template information, the target OFD board template and the target OFD structured data template are obtained.

[0056] Step S13: Write the object data into the target OFD board template and the target OFD structured data template respectively, so as to merge and package the generated result data to obtain an OFD file.

[0057] It is understood that the object data is provided by the customer. The object data provided by the customer is matched with the target OFD board template and the target OFD structured data template using the software development kit provided in this application. That is, the data is written into the board template and the structured data template respectively. In this way, the generated board data result is merged and packaged with the standardized structured data and assembled into the required OFD file.

[0058] In this embodiment, because fields and field labels were added to the OFD template when it was drawn before using the software development kit (SDK), each template has different fields, and labels are added to each field. <tag>Attributes allow for customization of the layout style based on fields and tags. Specifically, the target tags in the target OFD layout template are determined based on the object data, and the corresponding target fields are determined based on the target tags, so that the object data is written into the target fields. That is, the node fields in the layout template that correspond to the content to be filled are used.<ofd:TextObject> Added on <tag>The attribute can find the target tag, which can then match the data to the location where it needs to be written, and then write the data to the corresponding target field.

[0059] In one specific implementation, a method for writing object data into a target OFD board template is disclosed, see [link to relevant documentation]. Figure 2 As shown, the method includes:

[0060] Step S21: Determine whether the object data matches the target OFD template based on the font size of the object data.

[0061] Step S22: If the object data matches the target OFD template, then the object data is directly written into the target OFD template.

[0062] Step S23: If the object data does not match the target OFD template, the object data is adjusted according to the preset adjustment rules, and then the adjusted object data is written into the target OFD template.

[0063] In this embodiment, when writing object data into the target OFD template, an electronic document layout preview is achieved. During this process, there may be scenarios where the written data is too long, resulting in a poor preview effect. Therefore, the font size of the object data is used to determine whether it matches the space size of the node position in the template. That is, the width occupied by different font sizes is calculated to match the width of the template space, thus calculating a suitable font size for optimal display. It can be understood that if the current font size matches the template, it can be directly displayed using the current font size, and the object data can be directly written into the OFD template. If the current font size does not match the template, the object data is further adjusted using preset adjustment rules to ensure a reasonable display.

[0064] Specifically, the target font size of the object data is determined based on the space width of the target OFD template, and it is determined whether the target font size is less than a preset font size threshold. If the target font size is less than the preset font size threshold, the object data is dynamically wrapped according to a preset dynamic line wrapping rule to convert it into multiple lines for display. If the target font size is not less than the preset font size threshold, the object data is displayed based on the target font size. It is evident that this embodiment of the application can achieve adaptive font size and dynamic line wrapping. When the field space can be displayed in multiple lines, it will automatically convert it into multiple lines for display in conjunction with dynamic line wrapping rules, improving the user experience.

[0065] It should be noted that in cases of insufficient template space, this embodiment prioritizes reducing font size. For example, if the current template allows 50 characters to be displayed per line, but the current object data contains 55 characters, and reducing the font size allows for 60 characters of the current font size to be displayed per line, then the object data will be displayed in the reduced font size format. It is understandable that when there are too many characters in the object data, the font size cannot be reduced indefinitely, as this would also affect the visual experience. Therefore, setting a preset font size threshold allows the object data to be displayed normally. When the font size cannot be matched with the template even after reduction, a new line is displayed.

[0066] In another specific implementation, a method for writing object data into a target OFD structured data template is disclosed, see [link to relevant documentation]. Figure 3 As shown, the method includes:

[0067] Step S31: Obtain the attachment directory obtained after parsing the Extensible Markup Language file in the target template information.

[0068] Step S32: Match the object data with the target OFD structured data template, and use the matching results to create an attachment file in the attachment directory.

[0069] In this embodiment, structured data is written by locating the Attach directory through the Extensible Markup Language (OFL) file within the target template information. It is understood that the template itself is an OFD file, but it is empty and contains no data. After the object data is written to the OFD structured data template, an attachment file named "File Type_Related Time_Identifier Field.xml" will be created in this directory. This attachment file stores the structured data content. The generated structured data content is automatically generated by matching the OFD structured data template with the object data passed in by the user of the software development kit (SDK). The generated result data is then written to the attachment XML file for storage.

[0070] In this embodiment, after writing the object data into the target OFD layout template and the target OFD structured data template, the results of the two steps are merged and written back to the corresponding OFD directory. The generated data is then repackaged to generate a new OFD file containing layout content and standard structured data. In other words, the object data is converted using the standard structured template and stored as an attachment in the OFD file. Thus, for software development kit users, simply initializing the template, assembling the data, and calling the generation method are sufficient to complete the generation of the entire OFD file.

[0071] like Figure 4 The diagram shows the overall process for generating OFD files. First, the OFD template and the generated structured data template are packaged into the SDK package. Then, when using the SDK tool, the user inputs object data, and the tool writes the template's XML format file into the template and structured data respectively. The results from the two steps are then combined to assemble the data and obtain the OFD file.

[0072] Furthermore, the software development kit (SDK) in this embodiment can also parse the corresponding OFD files and extract standard structured data from them. Specifically, it obtains the OFD file to be parsed based on a JAVA interface; it parses the OFD file using the SSD, and matches the parsed data with the OFD template and the OFD structured data template to extract the corresponding standard structured data from the OFD file. In this way, by using the SSD tool in this embodiment, enterprises can generate corresponding electronic voucher files, and customers can extract standardized data for use, achieving unified standardization in the data flow process.

[0073] This application provides a method for generating OFD files, applied to a software development kit (SDK). First, object data uploaded by a user terminal is acquired. Then, target template information within the SSD is determined, and the Extensible Markup Language (XML) file in the target template information is parsed to obtain a target OFD layout template and a target OFD structured data template. Finally, the object data is written into the target OFD layout template and the target OFD structured data template respectively, and the generated results are merged and packaged to obtain the OFD file. Therefore, for SSD users, after determining the target template information in the SSD, they only need to write the object data uploaded by the user terminal into the OFD layout template and the OFD standard data structure template obtained after parsing the XML file to complete the entire OFD file generation. This technical solution reduces the complexity of the OFD file generation process, provides a unified structured data standard, and enables data extraction without relying on other devices, effectively improving the use and promotion of OFD files in fields such as electronic invoices and bank documents. In addition, OFD files can be parsed based on the template information in the software development kit, providing a solution for extracting standard structured data from OFD files.

[0074] Accordingly, this application also discloses an OFD file generation device, applied to a software development kit, see [link to relevant documentation]. Figure 5 As shown, the device includes:

[0075] Object data acquisition module 11 is used to acquire object data uploaded by the user terminal;

[0076] The template determination module 12 is used to determine the target template information in the software development kit and parse the Extensible Markup Language file in the target template information to obtain the target OFD board template and the target OFD structured data template.

[0077] OFD file generation module 13 is used to write the object data into the target OFD board template and the target OFD structured data template respectively, so as to merge and package the generated result data to obtain an OFD file.

[0078] For more detailed information on the working process of each of the above modules, please refer to the relevant content disclosed in the foregoing embodiments, which will not be repeated here.

[0079] Therefore, the above-described solution in this embodiment, applied to a software development kit (SDK), firstly acquires object data uploaded by the user terminal; then, determines the target template information in the SSD and parses the Extensible Markup Language (XML) file in the target template information to obtain a target OFD layout template and a target OFD structured data template; finally, writes the object data into the target OFD layout template and the target OFD structured data template respectively, merging and packaging the generated data to obtain an OFD file. Thus, for users of the SSD, after determining the target template information in the SSD, they only need to write the object data uploaded by the user terminal into the OFD layout template and the OFD standard data structure template obtained after parsing the XML file to complete the generation of the entire OFD file. The technical solution of this application reduces the complexity of the OFD file generation process, provides a unified structured data standard, and enables data extraction without relying on other devices, effectively improving the use and promotion of OFD files in fields such as electronic invoices and bank documents. In addition, OFD files can be parsed based on the template information in the software development kit, providing a solution for extracting standard structured data from OFD files.
