Geospatial Metadata Framework in Distributed Network Environments
-
摘要: 在研究现有的地理信息元数据标准定义的元数据框架及其管理模式的基础上,提出了一种可操作的、面向对象的元数据内容框架和分级的、基于地图的元数据组织方式,方便了分布式网络环境下地理信息服务的检索、查找和获取。Abstract: After examining the existing metadata standards and their implementation frameworks,this paper presents an operational,object-oriented metadata content framework and a hierarchical,map-based metadata repository architecture as an alternative for searching,indexing,and retrieving distributed GIServices on the Internet,and gives an instance for implementation.
