网格化数字图书馆体系结构分析研究

数字图书馆服务系统的架构极大的影响着其性能。本文描述比较了OpenDLib和GridDLib两种数字图书馆的架构,并着重阐述了汇聚层的服务。一个数字图书馆系统所提供的服务质量,不仅仅是取决于满足用户的直接需求,还受到汇聚层所提供的管理服务的影响。对于数字图书馆的架构设计,提出需要更深层考虑的问题。

The architecture of a digital library service system strongly influences its capabilities. The two infrastructures of the digital library, OpenDLib and GridDLib, are described. Their features are compared and their collective layer service is emphatically discussed. The QoS of a digital library system relies on not only satisfying the user＇s demands, but also the management services provided by the collective layer. In order to design a soundly digital library architecture, deeply problems which should be considered are listed in this paper.
