Questions tagged [freebase]

Freebase was a large, Google owned, community-edited, general knowledge semantic database that could previously be accessed via a RESTful API. It was shut down in 2016.

Freebase was a large, community-edited, general knowledge semantic database that could be accessed via a RESTful API. Its core information is derived from Wikipedia, MusicBrainz, and OpenLibrary, among other sources. It retains links to those sources, as well as a large number of other sources of strong identifiers (Library of Congress, New York Times, IMDB, etc), allowing cross-referencing among the various sources.

It was originally developed by Metaweb and is now owned by Google. Data can be reused under a CC-BY attribution license.

Freebase was shutdown on May 2, 2016, although extracts of the data are available.
