Agencies may integrate an existing system for maintaining unique identifiers. Each identifier **must** be unique across the agency's catalog and remain fixed. Characters should be alphanumeric. It is **highly recommended** that a [URI (preferably an HTTP URL)](http://tools.ietf.org/html/rfc3986#section-1.1.3), be used to provide a globally unique identifier. URLs should be designed and maintained to persist indefinitely regardless of whether the URL of the resource itself changes.
