Research on Metadata System and Model of Military Logistics Information Resources

摘要

Aiming at the problems existing in sharing and exchanging military logistics information resources, this paper firstly expands the core metadata of logistics information resources, constructs the content system of logistics information resources metadata, and displays it based on XML files. Then, the metadata model of logistics information resources is studied, and the mapping rules of logistics information resources metadata to logistics data sources are defined, including the mapping of metadata to relational database and the mapping of metadata to XML files. Finally, the paper puts forward some countermeasures and suggestions for the application of metadata in logistics information resources.
