摘要
资源发现是数字图书馆网格资源管理的核心内容之一,资源发现功能的强弱,直接决定了数字图书馆网格的使用效率和用户友好程度。要想实现数字图书馆网格对资源的有效共享,就必须采取一种高效安全的资源发现方法。当前基本的资源发现方法主要有四种:集中式资源发现方法、分布式资源发现方法、混合式资源发现方法和层次式资源发现方法。本文对这四种发现方法的工作原理以及优缺点进行了分析,并指出层次式方法是构建大型数字图书馆网格时资源发现方法的首要选择。
Resource discovery is one of the central content of resource management in digital library grid,and the efficiency of the function of resource discovery directly decides the resource usage efficiency and user-friendly interface of the digital library grid. In order to realize the high efficient resources sharing of the digital library grid,it must adopt a type of high security and efficiency method of resource discovery. Currently,there are four methods： centralized type,distributed type,mixed type and hierarchical type. In this article,the authors analyze the working principles of the four methods and its advantages and disadvantages. In the end,the authors consider that hierarchical type of resource discovery is the first choice when we construct a large-scale digital library grid.
