基于资源描述框架的煤地质学元数据描述方法

Metadata description method of coal geology base on resource description framework

资源描述框架(RDF)的制定是为了促进W eb元数据的创建及交换。为了满足煤地质学信息共享的需要,通过对煤地质学数据、煤地质学元数据进行综合分析,结合RDF及XML(可扩展的元置标语言)自身特点,提出了基于RDF描述煤地质学元数据的思路和方法,这使得煤地质学元数据可以与其他元数据标准进行交换,并可方便地进行扩展。中国煤炭特性数据库的元数据描述实例应用表明该描述方法可行、有效。

Resource Description Framework （RDF） is to promote the innovation and exchange of the Web metadata. In order to meet the share needs of the coal geology information, with the comprehensive analysis of the coal geology data and coal geology, metadate, and in combined with itself features of the RDF/XML, the paper provided the ideal and method to describe the coal geology metadata based on RDF, which could make the coal geology metadata exchange with other metadatas standard and could make easy to be extended. The Metadata description case application of the China coal characteristic database showed that the description method was feasible and effective.
