摘要

数字图书馆中介允许不同信息服务之间的互操作。在本文中，我们描述了一个灵活和动态的中介基础设施，它允许中介由一组模块(“刀片”)组成。每个模块实现一个特定的中介功能，如协议转换、查询转换或结果合并。中介使用的所有信息，包括中介逻辑本身，都由RDF图表示。我们将使用一个涉及Dienst和Z39.50服务器的中介场景来说明我们的方法，并讨论我们的框架的潜在优点和缺点。

A mediation infrastructure for digital library services

Digital library mediators allow interoperation between diverse information services. In this paper we describe a flexible and dynamic mediator infrastructure that allows mediators to be composed from a set of modules (``blades''). Each module implements a particular mediation function, such as protocol translation, query translation, or result merging. All the information used by the mediator, including the mediator logic itself, is represented by an RDF graph.We illustrate our approach using a mediation scenario involving a Dienst and a Z39.50 server, and we discuss the potential advantages and weaknesses of our framework.
