元数据互操作研究

Study in Metadata Interoperability

元数据互操作是实现各种类型资源统一检索的有效途径,本文从元数据自身特点及图书馆元数据使用现状两方面出发,论证了在数字环境下进行元数据互操作的必要性,基于CNMARC、MARC21、DC元数据的特点分析了在他们之间进行映射存在的问题,进而提出实现元数据互操作的几个途径。

Metadata interoperability is the effective way to realize the unified retrieval between the different types of resources. This article discusses the necessity of metadata interoperability in the digital environment from two aspects, one is the characteristics of metadata, another is the current situation of metadata used in library. Based on the characteristics of the metadata of CNMARC, MARC21, and DC, analyses the problem of mapping between them, and points out several ways to realize the metadata interoperability.
