Faceted Application of Subject Terminology

FAST (Faceted Application of Subject Terminology) is a simplified syntax for the Library of Congress Subject Headings (LCSH). FAST is developed as a part of WorldCat by the Online Computer Library Center, Inc. (OCLC), with the goal of making subject cataloging less costly and easier to implement in online contexts. FAST headings separate topical data from non-topical data, such as information about a document's form, chronological coverage, or geographical coverage.[1]

Unlike LCSH, which are pre-coordinated, FAST headings are post-coordinated.[2]


OCLC has been developing FAST since 1998, and originally intended the system to describe Web resources in simple metadata schemata, particularly Dublin Core.[1] FAST separates headings into eight distinct facets: topical, geographic, personal name, corporate name, form, chronological, title as subject, and meeting name.[3] Each facet can be mapped to a specific Dublin Core element. For example, the geographic facet can be mapped to the coverage element in the basic Dublin Core Metadata Element Set, and to the coverage.geographic element in qualified Dublin Core.

In keeping with Dublin Core's simplicity, FAST headings are meant to be "simple and easy to apply and to comprehend."[4] To facilitate subject assignment, OCLC has developed a tool called assignFast. This tool uses an autocomplete feature to assist catalogers with the details of FAST headings.[5]

OCLC has published FAST as linked data under an Open Data Commons Attribution (ODC-By) License.[6]


FAST's chronological periods have been critiqued as making little sense outside the context of full LCSH.[3] An OCLC study showed that several libraries that had adopted FAST were impressed by its "ease of use, simple syntax, [and] suitability for use by non-specialist staff." However, several libraries in the same study were discouraged by a lack of communication with OCLC.[7]
