地质空间信息元数据服务模式的实现

Implementation of the geological spatial information metadata service pattern.

地质空间信息元数据为解决地质空间信息的共享提供了有效的手段。从地质空间信息核心元数据的标准着手,介绍了基于分布式结点自治的地质空间信息元数据服务体系的结构,给出了元数据的服务模式的解决方案,其中重点阐述了元数据的管理、发布与服务功能。将该元数据服务模式应用于国家地质空间信息网格平台,提供元数据应用的服务示范,取得了良好的信息共享应用效果。

Geological spatial information metadata is an effective means to solve the sharing of geological spatial information. Proceeding from analyzing the core metadata standards of geological spatial information, this paper introduces the metadata service architecture of geological spatial information based on the distributed autonomous nodes and gives the solution scheme of the metadata service pattern, with emphasis on the metadata management, distribution and service function. So far, the metadata service pattern has been implemented in the national geological spatial information grid platform and offers a service demonstration of metadata applications, and good data sharing and application results have been yielded.
