摘要： 互操作是实现数字图书馆(DLs)的集成(或联邦)需要解决的关键问题,其目的是将Web上广泛分布的、自治的、异构的DLs联合起来,利用统一的查询界面实现对多个DLs的透明访问。首先介绍了DLs互操作的实现方法,并指出了各自的优缺点;在此基础上,提出一 种基于移动Agent的DLs互操作框架,并给出了基于该框架实现的一个原型系统。

Abstract: Interoperability is a key issue to be solved for digital libraries(DLs)integration or federation, which aims at integrating distributed, autonomous and heterogeneous DLs on the Web and providing a transparent access for multiple DLs via a uniform query interface. The approaches for DLs interoperability are introduced and the advantages and disadvantages for each are discussed. Based on that, this paper presents a mobile agent based framework for DLs interoperability. The implementation of prototype based on this framework is described.
