I think it's quite "old" -- languished for some time. but lives on... http://www.cdlib.org/inside/diglib/ark/arkcdl.pdf December 2004: "The ARK Identifier Scheme: A New NISO Registration" The newest NISO registration is the ARK (Archival Resource Key) Persistent Identifier Scheme, a collaborative effort with IETF members and the California Digital Library was approved as a NISO Registration In December. ARK facilitates the persistent naming and retrieval of information objects. It is made up of an identifier syntax and three services, defined initially to use the HTTP protocol. Details on the scheme can be found at http://www.ietf.org/internet-drafts/draft-kunze-ark-08.txt. The NISO Registration Process is a lighter-weight review and accreditation to existing specifications developed outside the formal standards process. Approval of a registration such as the ARK requires a 30-day review and ballot period and approval by 15 percent of the members. Details about the NISO Registration process are at http://www.niso.org/registration/registration.html. [which says:] Registration Title: The ARK Persistent Identifier Scheme NISO Member approved date: November 2, 2004 SDC Renewal Approval Date: July 19, 2006 URL of electronic copy: http://www.cdlib.org/inside/diglib/ark/arkspec.pdf Contact person: John Kunze, Email: jak@ucop.edu The ARK (Archival Resource Key) is a scheme intended to facilitate the persistent naming and retrieval of information objects. The Archival Resource Key (ARK) is relevant to any community that desires long-term references to information objects. ARK identifiers work in today's web browsers without compromising the core, technology-independent identities that they contain, and that are designed to outlast the HTTP era. ARKs are the only identifiers required, by definition, to connect users to the three minimum services underlying credible persistence provision: to the object itself (or a suitable surrogate), to object metadata, and to a commitment statement. The ARK scheme is an open, pragmatic, low-cost solution that builds on experiences gained with predecessor schemes that have addressed the problem of persistent identification: DOI, URN, and PURL, the OpenURL. All of these schemes, including ARK, rely on the URL specification itself to create services that work in today's internet environment. The ARK scheme was developed at the US National Library of Medicine, with the current focus of development and maintenance being the California Digital Library (CDL). The CDL is committed to this scheme and is using ARKs for all of the digital objects that it owns or controls. The CDL will assign or delegate assignment of ARKs to all of its contributors, including the ten campuses of the University of California, the California State Universities, and the public libraries of California. > > > > The ARK syntax can be summarized, > > [http://NMAH/]ark:/NAAN/Name[Qualifier] > > > > They even have the concept of a "proxy" HTTP just like ours - see section > 2.1 > > > > 2.1.
