基于XML的空间元数据系统的研究与设计

Research and Design of the Spatial Metadata System Based on XML

空间元数据系统是网络环境下解决空间信息共享的主要途径之一,笔者探讨了建立空间元数据系统所涉及的一些标准和技术,重点介绍XML技术及其在元数据系统中的作用,同时,制定出元数据系统设计的原则,并设计出一种基于XML的空间元数据系统体系结构.

Spatial metadata system is one of the key methods to geographical information sharing in the net.In this article,the author discusses some standards and technolgies,which deals with the creation of spatial metadata system,at the same time,introduces XML and its function for spatial metadata system,also puts forward the principle for designing metadata system.A XML-based systematic construction of spatial metadata system is designed.
