摘要
Metadata mechanism, especially metadata management pattern, is a hotspot in the field of internet information sharing. This paper analyzes the characters and deficiency of current metadata management patterns. Subsequently, a new metadata management pattern is put forward combined with its application in geograpic information sharing. Aiming at the demands of future Internet information sharing, this pattern is a networkoriented, open and extensible metadata management system. Meanwhile, this management pattern is also a management model of trinity of data users, metadata and datasets. Finally, this paper analyzes the architecture and function flow of this network-oriented integrated metadata management pattern.
