FAST is an enumerative, faceted subject heading schema derived from the Library of Congress Subject Headings (LCSH). OCLC made FAST available as Linked Open Data in December 2011.
The bulk downloadable versions of FAST are offered at no charge. Like FAST content available through the FAST Experimental Linked Data Service, the downloadable versions of FAST are made available under the Open Data Commons Attribution (ODC-By) license.
FAST may be downloaded in either SKOS/RDF format or MARC XML (Authorities format). Users may download the entire FAST file including all eight facets (Personal Names, Corporate Names, Event, Uniform Titles, Chronological, Topical, Geographic, Form/Genre) or choose to download individual facets (see the download information page for more details).
OCLC has enhanced the VoID ("Vocabulary of Interlinked Datasets") dataset description for improved ease of processing of the license references. Several additions and changes to FAST headings have been made in the normal course of processing new and changed headings in LCSH. OCLC will continue to periodically update FAST based on new and changed headings in LCSH.
The FAST authority file, which underlies the FAST Linked Data release, has been created through a multi-year collaboration of OCLC Research and the Library of Congress. Specifically, it is designed to make the rich LCSH vocabulary available as a post-coordinate system in a Web environment. For more information, see the FAST activity page.
