| 摘 要： | 提出一种基于XDR纲要的空间元数据存储体系结构，建立XDR纲要，将以XML表达的空间元数据映射到SQL Server 2000关系数据库中，可以使用加注释XDR纲要的XML视图对应到数据库的查询，并以XML文件的形式返回查询结果。

| Abstract: | A storing systematic configuration of spatial metadata based on XDR Schema was proposed and a XML data reduced schema was created. The spatial metadata expressed by XML was mapped to SQL Server 2000 RDBMS. The annotated XDR schema corresponded with XML view, so we could query database using annotated XDR schema and get result in XML form. |
