摘要

摘要: 根据地学元数据描述对象的差异, 把地学元数据分为数据库元数据、数据集元数据和数据要素层元数据, 不同层次元数据在管理使用上有一定差异.地学元数据研究中最关键、最基础的内容是元数据标准的制定和使用, 从实用性角度出发, 结合已有的地学元数据标准, 提出了一种分为基本集、概要集和详细集三层结构的地学元数据体系, 每层次的元数据适用于不同的用户群.根据已有的元数据使用的成功经验, 总结了几种元数据使用和管理模式.

Abstract: The geological metadata can be classified, on the basis of the difference in objects described by the geological metadata, as the metadata for the database, the metadata for the data set and the metadata for the data element layer. A certain difference arises in the management and the metadata in different layers. The most essential element in the research into the geological metadata is to formulate and utilize the metadata standard. In this paper, a three layer geological metadata system consisting of a basic metadata set, a summary metadata set and a detailed metadata set, is presented for the practical application and in line with the geological metadata standard available now. Each layer of metadata is appropriate to its corresponding user group. In this paper, is finally summarized the patterns for the utilization and management of several metadata, on the basis of the present successful experience on the utilization of the metadata.
