摘要 

在空间数据应用范围日益拓宽的同时,空间元数据的共享问题成为限制其发展的主要瓶颈之一。本文分析了目前我国空间元数据管理中存在的问题,列举了两种可行的空间元数据共享策略及相应的国际标准,探讨了面向共享的空间元数据的管理框架。

Abstract

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.
