FAST (Faceted Application of Subject Terminology)

FAST (Faceted Application of Subject Terminology) is an enumerative, faceted subject heading schema derived from the Library of Congress Subject Headings (LCSH). The purpose of adapting the LCSH with a simplified syntax to create FAST is to retain the very rich vocabulary of LCSH while making the schema easier to understand, control, apply, and use. The schema maintains upward compatibility with LCSH, and any valid set of LC subject headings can be converted to FAST headings.

FAST Linked Data

Linked Data is one of the underpinnings of the Semantic Web, the effort to make the meaning of information on the Web more understandable to computers. These Linked Data authorities are formatted using SKOS (Simple Knowledge Organization System). A search API is available to help identify and select headings for use.

The Linked Data version of the FAST authorities also incorporates links to corresponding LCSH authorities. In addition, many of the geographic headings have links to the GeoNames geographic database.

The use of the FAST authorities is open and FAST is made available under an Open Data Commons Attribution (ODC-By) License. It is also available for download under this license at OCLC will update FAST periodically, at least twice yearly.
