本文提出了基于OAI的数字图书馆网格应用系统的框架结构,为建立一个有效的数字图书联盟提供了可能,可以有效解决多个异构数字图书馆之间的资源共享问题。并重点研究如何利用网格技术在基于OAI框架的数字图书馆联盟中进行并行收割,同时还提出了利用OpenURL技术获取原文的方法。 In this paper, the framework of OAI-based digital library grid application system is proposed, which offers the possibility of establishing an effective digital library alliance and can effectively solve the problem of resource sharing among heterogeneous digital libraries. And focuses on how to use grid technology to parallel harvest in the OAI-based digital library consortium. At the same time, a method of using the OpenURL technology to obtain the original text is also proposed.
