摘要 数字对象唯一标识符作为数字图书馆的基础设施,具备网络环境下数字对象的标识、定位、管理等多种职能。本文分析了唯一标识符的类型、组成和构造原则,从逻辑标识、命名域相关、复杂性、完整性和互操作等角度论述唯一标识符的需求。在W3C提供的URI背景下,比较URI、URL和URN,并分析了相关命名语法和标识框架。最后介绍了COOL URL的概念和命名需求。

Abstract :As the infrastructure of digital library, digital object unique identifier is responsible for identifying, locating and managing of digital objects. This article discusses the types, component and principle of unique identifier, and analysis the demand of unique identifier from the logics,namespace,complexity,integratity and interoperability. Next ,the difference and relation have been compared among URI,URL and URN. Those syntax and identifying framework are also introduced. At last Cool URL is discussed in detail.
