摘　　要：为了解决In ternet上大规模的数字图书馆互操作问题,在原有OA I-PMH框架的基础上,提出一种基于网格技术的数字图书馆互操作框架——数字图书馆网格(DL grid),给出了3层DL grid体系结构,并对元数据资源的发现、采集、重组、利用等关键技术进行了分析、设计与实现.通过集成的元数据,实现了W eb上数字图书馆信息的共享.In order to realize a large-scale digital library interoperability on Internet, a grid technology based framework is put forward, a digital library grid, which is based on OAI-PMH framework, and an architecture with three levels for DL grid is given. To construct the DL grid, some crucial technologies are discussed, designed and achieved, such as discovering and harvesting of metadata resources, re-building of metadata resources and utilization of metadata resources. Through using integrated metadata resources,the system realizes information sharing of digital libraries on Web.
