The Faceted Application of Subject Terminology (FAST) Authority File is a project of he OCLC Office of Research.

Frequency of Data Update
Our target is to update FAST at least twice a year.
FAST is capable of content negotiation for requested URLs. Therefore different Accept/Header retrieves content in different formats. Below is a table of the Accept/Headers recognized by FAST, the format of the corresponding response and the corresponding URL for accessing the data without using Accept/Headers
|accept header||response format||url|
