Random information on the term “URN”:

An Archival Resource Key (ARK) is a Uniform Resource Identifier (URI) that is a multi-purpose persistent identifier for information objects of any type. An ARK contains the label ark: after the URL’s hostname, which sets the expectation that, when submitted to a web browser, the URL terminated by ‘?’ returns a brief metadata record, and the URL terminated by ‘??’ returns metadata that includes a commitment statement from the current service provider. The ARK and its inflections (‘?’ and ‘??’) provide access to three facets of a provider’s ability to provide persistence.

Implicit in the design of the ARK scheme is that persistence is purely a matter of service and not a property of a naming syntax. Moreover, that a “persistent identifier” cannot be born persistent, but an identifier from any scheme may only be proved persistent over time. The inflections provide information with which to judge an identifier’s likelihood of persistence.

ARKs can be maintained and resolved locally using open source software such as Noid (Nice Opaque Identifiers) or via services such as EZID and the central N2T (Name-to-Thing) resolver.
