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.
