The construction of ASTICM has started from the proposed elements of the DCMI (Dublin Core Metadata Initiative), and has expanded the DC and SDBCM with related expanding principles. ASTICM finally includes 75 metadata elements, five expanded principles, and seven application profile creation methods. According to the requirement analysis of a large number of users of agricultural information, a register system based on ASTICM was developed. The ASTICM standard framework and its register system supported the search, sharing, integration exchange and other applications, effectively.展开更多

The prototype of metadata standard for the construction is designed and established by using a modeling method, and the framework with XML/RDF for such standard is given.展开更多
