The service provides a registry of permanently valid resource identifiers for entities within the GÃ‰ANT infrastructure that serves European educational institutions and affiliated people. For each registered resource, a Uniform Resource Name (URN) is logged in a format resembling an http:// web address. Each URN is associated with an http:// URL where that resource is currently accessed. If the resource must move to a new URL, the registry listing may be updated, allowing the persistent identifier to redirect to an updated location and access the resource.
API methods support submission of a request containing a URN with special characters in escaped format. The API returns the current URL associated with that identifier. Methods also support listing all currently registered URNs and their associated URLs.
