基于标签本体的MARC元数据扩展机制研究

摘要

The application range of MARC metadata is very wide and its structure is complex. Moreover, its format design and mode of thinking is flawed. But the mapping method between tag ontology and MARC metadata can effectively solve these problems. The essence of the mapping method between tag ontology and MARC metadata is establish a mapping table and then the MARC metadata could be described by the form of RDF. The aim of the mapping method is to provide a variety of information resources retrieval approach by considering the requirements of the user.%M A RC元数据应用范围广泛，但其结构复杂，格式设计和思维设计也存在缺陷，通过标签本体与MARC元数据的映射方法能够有效的解决这些问题。标签本体与MARC元数据映射方法的实质是通过建立两者之间的映射对照表，将MARC元数据用标签的RDF三元组形式进行描述，目的是从用户需求的角度提供信息资源的多种检索途径。
