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.展开更多

Engineering data management systems are needed to be able to manage the unified data and to be both customizable and extensible. The design of the systems is heavily dependent on the flexibility and self-description of the data model. The characteristics of engineering data and their management facts are analyzed. Then engineering data warehouse (EDW) architecture and multi-layer metamodels are presented. Also an approach to manage anduse engineering data by a meta object is proposed. Finally, an application flight test EDW system (FTEDWS) is described and meta-objects to manage engineering data in the data warehouse are used. It shows that adopting a meta-modeling approach provides a support for interchangeability and a sufficiently flexible environment in which the system evolution and the reusability can be handled.展开更多
