SRU defines a protocol for search and retrieval, utilizing CQL (Contextual Query Language), a standard query syntax for representing queries. SRW (Search Retrieve Web Service) is a companion protocol to SRU. SRU is used to search databases containing metadata and objects, both text and non-text. The SRU Initiative builds on Z39.50 along with web technologies. Building on Z39.50 semantics enables the creation of gateways to existing Z39.50 systems; web technologies reduce the barriers to new information providers allowing them to make their resources available via a standard search and retrieve service.
SRU is maintained by the Library of Congress (see http://www.loc.gov/sru), with support from the SRW Editorial Board (see http://www.loc.gov/sru/board.html), as well as an implementor group which communicates over a public listserv.
Registration Title: The ARK Persistent Identifier Scheme

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.
