Persistent Uniform Resource Locator

from Wikipedia, the free encyclopedia

A Persistent Uniform Resource Locator or PURL is an identifier in the form of a URL that is not an Internet - resource refers, but indirectly to a link resolver that returns the actual, current URL of the resource. From the user's point of view thus a PURL corresponds to an HTTP - forwarding . PURLs are - like URNs - a way of providing constant, persistent (= permanent) references to the content of websites , while the actual addresses of the pages can remain variable. PURL was managed by the Online Computer Library Center (OCLC) from 1995 to 2016 . The Internet Archive took over this task on September 27, 2016 .

Alternatives to PURL are, for example, digital object identifiers , the handle system and uniform resource names .
