【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.更多还原

【Abstract】 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.更多还原
