FAST has been a multi-year project of OCLC Research in collaboration with the Library of Congress. The FAST authority file is an enumerative, faceted subject heading schema derived from the Library of Congress Subject Headings (LCSH).
You can read the details in the press releases and announcements but even better would be to take a look at the web search interface to FAST. You can also see a nice example of FAST in action by looking at MapFAST which uses FAST to show library materials using the geographic focus of the content.
FAST itself has been a lot of work over many years and I was pleased that Ed O’Neill who led the project was here in our San Mateo offices when the release occurred. We were able to give him a big round of applause. Of course, this project demanded a broad range of effort from many Research staff over the years but the principal developer and the kingpin in the linked data release is Rick Bennett. We applauded him virtually.
Now I hope to sit back and hear about the interesting ways that FAST is mobilized in the linked data cloud.
