基于XML/RDF的MARC元数据描述技术

MARC Metadata Description Approach Based on XML/RDF

由W 3C推出的元数据标准可扩展标记语言XML和资源描述框架RDF分别规范了In ternet上资源描述的语法和语义 ,为元数据的编码、交换和重用提供了基础架构。本文针对目前广泛存在于图书馆系统中的MARC格式的大量书目数据 ,研究了基于XML/RDF的MARC元数据描述技术 ,重点解决了MARC元数据的XML描述问题和基于RDF的MARC元数据描述问题 ,从而使得专用的MARC规范格式的书目数据转换成通用的机器可读和机器可理解的元数据成为可能。

Extensible Markup Language (XML) and Resource Description Framework(RDF), these metadata standards announced by W3C,standardize the resources description syntax and semantics on Internet respectively,and offer an infrastructure for the encoding,exchange and reuse of metadata.In this paper,considering the large amount of MARC data in numerous library systems,we present the MARC metadata description approach based on XML/RDF.We mainly solve the problems on the MARC mtadata description based on XML and RDF respectively.It enables the possibility of the conversion from the MARC specific format metadata to the general machine readable and machine understandable metadata.The achievements of our research will contribute to the existing MARC data utilization in digital library in the future.
