Abstract
A PURL is a Persistent Uniform Resource Locator. Functionally, a PURL is a URL (Uniform Resource Locator). However, instead of pointing directly to the location of an Internet resource, a PURL points to an intermediate resolution service. The PURL project is a result of OCLC participation in the Internet Engineering Task Force (IETF) Uniform Resource Identifier working groups. PURLs satisfy many of the requirements of Uniform Resource Names (URNs). They use current technologies and can be transitioned smoothly into a URN architecture once it is in place.
