XML-based OAIS information packaging method and XML-based OAIS information packaging system

Abstract

The invention provides an XML-based OAIS information packaging method and XML-based OAIS information packaging system. The packaging method comprises the following steps of: collecting file data and metadata by virtue of XML, carrying out the physical packaging according to a structural relation of the file data and the metadata, and generating at least one submission information package; identifying, compiling and filing the submission information package, packaging, by using XML, the metadata generated during the identification, compiling and filing by adopting a physical packaging way into the submission information package after being identified, compiled and filed to generate at least one archival information package; and acquiring target archive data from the archival information package according to a request instruction of a user, and packaging, by using XML, the target archival data by adopting a physical packaging way to form at least one distribution information package, and allocating the distribution information package to the user. The XML is used as a data exchange format for implementing an OAIS model, the isomerism of data acquired at the bottom layer can be shielded, the packaging is flexible, and the integrity and long-term persistence of the archive can be guaranteed by adopting the physical packaging.

Description

technical field [0001] The invention relates to the technical field of file management, in particular to an XML-based OAIS information encapsulation method and system. Background technique [0002] Aiming at the problems of scattered archives management information and lack of storage, the OpenArchival Information System (OAIS) model provides the idea and framework of archives information packaging. The OAIS model provides the environment and text description of archives management. , information, and archives fields can be practically applied standards. [0003] The data basis for establishing the OAIS model is encapsulation. According to the functions of archive information, archives are encapsulated into different types of information packages. There are three types of information packages in the OAIS model: Submission Information Package (SIP, Submission Information Package), Archive Information Package (AIP, Archival Information Package) and Dissemination Information P...

Problems solved by technology

Therefore, the time overhead of encapsulation and decapsulation of data packets will continue to increase with the use of information systems

[0006] 2. The way of logical encapsulation can solve the problem of efficiency very well. File data and metadata are encapsulated in the form of links, and links are established between metadata and metadata, between metadata and file data, and between file data and files. The logical structural relationship between data, this method has achieved good efficiency, but the logical relationship is easily destroyed. During data migration, the change of data storage location may cause link failure. In project file management, link failure leads to the need to reorganize and package file data and metadata, which will be disastrous

However, this method also brings corresponding problems: First, the doubling of the data volume wastes storage space. In the cloud storage method, enterprise users need to pay double fees to store these data; second, when the data is maintained or changed , the data synchronization between the physical data packet and the logical data packet will become more and more cumbersome. If there is an error in the synchronization, the reconstruction and recovery of the data packet will be invalid, and the retrieval result of the logical data packet cannot guarantee real-time performance.

[0008] As the number of project files continues to increase, the problem of long-term storage of files has become increasingly prominent, and when files are stored in the cloud, data migration is very easy to damage these logical links. In information retrieval, the efficiency of encapsulation and decapsulation will still be encountered

Therefore, there is an urgent need for a packaging method to solve the problems of long-term storage of files, scattered information, and missing storage
