[0041] In order to solve the problems existing in the prior art, the present invention provides a method, device, medium and equipment for constructing a preservation data model for digital archives, which can realize the long-term preservation of data, tools, and the connection relationship between tools and data, thereby being more suitable for practical use.

[0042] After arduous efforts, the inventors found that the existing main problems are as follows:

[0043] (1) Long-term archive storage only manages digital archive data, and does not retain the tools that generate the archive data.

[0044] The digital archives are transferred to the digital archive system, and the data are archived according to the management requirements, including OFD or PDF files and original files. In the process of archive reception / management, the tools for generating the transferred data are not archived. Digital archives need to be kept for a long time. During the storage period, the tools for generating archive data are constantly changing with the development of digital technology, or the manufacturers of digital archive generation tools will also change, resulting in the long-term preservation of archive data cannot be read, reused, displayed by future tools, or even no tools are available.

[0045] (2) Long-term archive storage is good at managing unstructured data, but structured data management is a weakness

[0046] Long-term storage of digital archives. Before archiving, most of the digital archives received into the digital archive system are unstructured data, and even if there is structured data, the amount is very small. With the further promotion of the single-set system of digital archives, the amount of structured data continues to increase, and the problem of how to store structured data for a long time is bound to arise.

[0047] (3) There is no complete system for long-term storage of digital archives under the single-file system.

[0048] The single-set digital archive system is an inevitable trend and result of the development of archive management driven by digital technology. In the reception, management and archiving of archives, the single-set digital archive system is implemented, and the means of long-term archive storage must meet the requirements of the single-set digital archive system. Digital archives include unstructured, semi-structured and structured archives, and the tools for generating digital archives include file, data and management tools. The long-term storage of archives under the single-set digital archive system requires the establishment of a management system for the single-set digital archive system.

[0049] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the method, device, medium and electronic device for constructing a data model for preserving digital archives proposed by the present invention, its specific implementation, structure, features and effects, in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, the features, structures, or characteristics of one or more embodiments may be combined in any suitable form.

[0050] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B. Specifically, it is understood that: A and B may be included at the same time, A may exist alone, or B may exist alone, and any of the above three situations may be met.

[0151] 4. Tools-Data Bridge Connector

[0152] The tool-data bridge connector consists of one-to-many and many-to-one connector types, such as one tool component connecting multiple data units and multiple tool components connecting one data unit.

[0153] (1) A one-to-many connection component is composed of (data format A, tool component 1), (data format A, tool component 2), (data format A, tool component 3), ...

[0154] (1.1) When a default tool component name exists in a data unit, the tool component is located through the tool-data bridge connector, the tool component service entry is obtained, the tool component service is locked, and the tool component service is released after the service is completed.

[0155] (1.2) When the data unit does not have a default tool component name, the data unit returns multiple tool components that can provide services through the tool-data bridge. Get the first tool component service entry, try to lock the tool component service, if the lock is successful, get the tool component name, and release the tool component after the service is completed. If the lock fails, get the second tool component service entry, and try one by one until success.

[0156] (1.3) If the returned multiple tool components cannot be locked, the tool-data bridge obtains the first tool component service, obtains the tool image of the tool component, automatically deploys the image, and the tool component image provides tool services. After the service is completed, the tool component service is released, the image is recycled, the occupied resources are released, and the tool component service is scalable.

[0157] (2) The many-to-one connection part is composed of (data format B, tool component 4), (data format C, tool component 4) (data format D, tool component 4),...

[0158] (2.1) When a default tool component name exists in a data unit, the tool component is located through the tool-data bridge connector, the tool component service entry is obtained, the tool component service is locked, and the tool component service is released after the service is completed.

[0159] (2.2) When the default tool component name of the data unit is occupied by other tool components, or there is no default tool component name, the tool-data bridge obtains the tool image of the tool component, automatically deploys the image, and the tool component image provides tool services. After the service is completed, the tool component service is released, the tool image is recycled, and the occupied resources are released, so that the tool component service can be scalable.

[0160] (3) A one-to-one connector is composed of (default tool component name 1, tool component 1), (default tool component name 2, tool component 2) (default tool component name 3, tool component 3), ...

[0161] (3.1) When a default tool component name exists in a data unit, the tool component is located through the tool-data bridge connector, the tool component service entry is obtained, the tool component service is locked, and the tool component service is released after the service is completed.

[0162] (3.2) When the default tool component of the data unit is occupied by other tool components, the tool-data bridge obtains the tool image of the tool component, automatically deploys the image, and the tool component image provides tool services. After the service is completed, the tool component service is released, the tool image is recycled, the occupied resources are released, and the tool component service is scalable.
