EIA-0091489 Nancy WiegandUniversity of WisconsinDigital Government：Integrating Metadata Development XML，and DBMS Search and Query Techniques in a State of威斯康星州土地信息系统这个项目将涉及几个州，地方和国家机构，开发一个异构空间和文本数据的可查询数据库。 这些数据将继续保存在各种地方数据库和其他数据库中，但似乎将通过有待开发的系统进行整合。 需要自动开发元数据和语义转换。 三个技术要点是i）定位和搜索数据源，以及支持用户对数据的操作。 XML将成为项目中表达元数据的重要技术工具。

EIA-0091489Nancy WiegandUniversity of WisconsinDigital Government: Integrating Metadata Development XML, and DBMS Search and Query Techniques in a State of Wisconsin Land Information SystemThis project will involve several state, local and national agencies in developing a query able database of heterogeneous spatial and textual data. The data will continue to be held in various local and other databases, but will appear to be integrated though the system to be developed. Automated development of Metada and semantic conversions will be required. Three technical thrusts are i) to locate and search data sources, and to support user manipulation of the data. XML will be an important technical tool in the project in expressing Metadata.
