摘要
通过对地理信息元数据标准的剖析,探讨了元数据管理系统开发的基本构架.结合水利工程地理信息元数据的特点设计了水利工程元数据标准,并以此标准为基础建立了关键词词库,实现了水利业务数据的全局检索,对元数据库建设具有重要的借鉴价值.
By analyzing famous geographic information metadata criteria at home and abroad, basic concept of metadata and development of metadata management system are discussed. On this basis, in combination with water project geographic information metadata characteristics, water project metadata criteria are established. And the dictionary built on the basis of these criteria allows searching for hydraulic business data thoroughly and has important reference value for metadata bank building.
