Metadata Standardization and Application for Core Information Based on XML

Due to the lack of a unified presentation format, the resource for core information is clearly under-utilized at present. To improve the utilization of core information, as well as facilitating the sharing of information among users and other softwares, the format should be standardized for organization, storage and data exchange. Relative technologies are being developed for auto-storage, interpretation and analysis of core information via software. Referring to the relative reference materials and technique standards worldwide, the authors created the standards of metadata for core information. XML technology can be used to create the XSD regarding to respective metadata standards, which has been implemented successfully in application programs. Using the XML data file generated by corresponding XSD, different users can interpret the core information correctly during interaction. With metadata standardization for core information, the organization, storage and data exchange format can be normalized automatically via software using XML technology. Results show an improvement in the efficiency of users, facilitated information by sharing, and enhanced the utilization of core information.
