基于DC、CDLS、FRBR的地图元数据规范比较研究

The Comparative Study of Map Metadata Standards based on DC,CDLS,FRBR

为了探讨现有地图元数据规范的特征,对基于DC、CDLS、FRBR的地图元数据规范进行对比分析,发现三者在著录对象、著录对象的关系揭示、元素组成等方面存在异同,对地图的描述与揭示各有侧重。认为,应加强各种地图元数据规范自身的完善、加强不同规范间的互操作性,同时建立对现有规范的评价与完善机制。

In order to research the features of existing map metadata standards,three map metadata standards based on DC,CDLS,FRBR are analyzed. It is found that there are differences in description object,relationship revealing of description object,elements composition and map＇s description and reveal. It is thought that the map metadata standards and the interoperability between these standards should be strengthened. At last,that the evaluation and perfect mechanism should be established is put forward.
