OCLC MapFAST API - Source Code

The service provides place names for geographic locations as specified in the Faceted Application of Subject Terminology (FAST) list of subject headings. That list adapts the authoritative subject headings from the U.S. Library of Congress (LCSH) for simplified application of complex rules. The streamlined structure allows rigorous application of standard terminology across large volumes of materials within manageable workflows. The service applies a subset of those terms identifying places by standard names based on location coordinates. API methods accept one or more locations based on latitude and longitude plus a radius specifying the size of the region of interest. The API returns the applicable term(s) from the FAST list.
