基于元数据的文献检索系统研究

Research on Document Indexing System Based on Metadata

元数据技术是数字图书馆系统的核心,通过它可以对文献资源实施有效的组织与管理,为此提出了以都柏林核心集为基础的元数据设计方法。为了提高各图书馆信息系统之间的互操作性,采用可扩展标记语言(XML)作为元数据交换语言,建立了一套元数据文献检索系统,并阐述了系统的特色、架构、功能及使用方式。

Metadata technology is the core of the digital library system,which can effectively organize and manage the literature resources. A metadata design method based on Dublin Core set is proposed. In order to improve the interoperability between the library information systems,a set of metadata retrieval system has been established using extensible markup language（XML）as the metadata exchange language. Furthermore,the system characteristics,structure,function and use are illustrated.
