摘要
提出一种基于最新的元数据互操作协议———OAI的元数据互操作框架。文章给出了框架中各个组件的模块及功能说明,并说明各模块之间的交互。这种框架克服了以前人们所提出的其他集成方法过于复杂、难于实施的缺点。
With the explosive increasing of network resources,how to search and share them has become an urgent problem to solve.Metadata is the basis for resource sharing and discovering,but with the diversity of resource,there won't a single metadata standard to describe all types of network resources.The interoperability of metadata is now the focus of digital library community.This paper addresses the limits of OAI -a newly released protocol aiming at metadata harvesting,and proposes a framework for metadata interoperability based on OAI.The paper gives the details of every component and its function,and illustrates the interaction between components.
