Geospatial metadata is a main means to share information under the heterogeneous environment. Unfortunately, most GISapplications define metadata differently, each using its own programming structure, syntax and semantics to model the metadata. These incompatibilities make it difficult for an application to discover and interchange data maintained by another application. Aiming at solving this problem, the authors have studied the sharing-oriented framework of geospatial metadata management. First, the existing problems of metadata sharing in China are analyzed, then two strategies for metadata sharing, i.e., Metadata repository and Metadata interchange, are put forward, and finally a framework for metadata sharing based on MOFand XMIis designed.
