摘　　要：OpenURL框架提供了新的描述资源的途径。OpenURL链接解析器使资源与服务无缝集成。当前支持解析器工作的后台知识库都是集中式的，或者委托第三方代理管理与维护。本文首先简要介绍开放链接标准、开放链接系统提供的扩展服务形式、知识库的总体结构，然后详细阐述链接解析器的工作流程及开放链接系统架构，并开发出开放链接服务系统原型。在分析开放、分布式环境下链接解析器工作原理的基础上，提出并实现了分布式知识库的构建与维护。最后给出了实例说明。OpenURL is a new way that describes objects, and link resolver leads to achievement of seamless linking to referenced article. But now all knowledge bases supporting the link resolver are almost centralized. Firstly this paper introduces OpenURL Framework, extend services, and the structure of the knowledge bases. Then details the workflow of link resolver and the architecture of the OpenURL system. And a prototype system was developed. This paper also proposes and implements distributed knowledge bases, we explain the principle of openURL link resolver and analyze the the resolver＇ s flow in distributed environment. Finally some codes are given.
