Abbreviation Of: 

n. (PURL, abbr.) ~ Computing · 1. A stable Uniform Resource Locator (URL) that provides a redirection to a resource's current URL. - 2. A service that offers such redirection.


A PURL service provides a means to link a stable URL to a resource, even if the resource's location changes. A PURL service maintains a simple database of PURLs and the associated, current URLs. A PURL published in different places can continue to point to the resource with a single change to the database, rather than having to change all published versions.
