Research And Implementation Of Metadata Management System In Guangxi Beibu Gulf Of Scientific Data Sharing Platform

Scientific data as important resources for the sustainable development of modernscience, is the important support of scientific and technological innovation, Inspiredby the current wave of information, there is an urgent need to establish a research dataplatform and services for the regional research, provides platform support for theintegration of regional data resources. Metadata share is the application of universaland effective sharing of data integration technology, This article is based on metadatasharing, discussion on the establishment of the service in the Beibu Gulf area ofscience data sharing platform-related theory and technology. Full text of the mainwork:1) project summary of the study on the background and associated metadata.Analysis in Beibu Gulf of science data sharing platform construction, advances athome and abroad, establishing the main objectives and content of the study, discussesthe theory and key technology of data sharing.1) project summary of the study on the background and associated metadata.Proceed from the item’s actual discussed meta-database design, indexes of themetadata, rights management, and meta-data storage management method, proposedXHTML files and meta-data storage and the combination of relational databasemanagement strategies, research based on XML Schema metadata extensionmechanism, proposed a extension model and implementation methods; From themeta-data sharing features, security control, show metadata, metadata interoperability,meta-data sharing strategy was discussed, proposed metadata browsing mode staticXHTML pages, discussion on the automatic harvesting of metadata technology needsfurther research.3) metadata management system design and implementation. First of all on thefunction of system construction of system architecture, system architecture,development environment and language profiles. And then discuss Data managementand separately from the background and the foreground two subsystems of the shared services Web site design and implementation perspective made a presentation.
