Metaweb

Metaweb Technologies, Inc. was a San Francisco-based company that developed Freebase, described as an "open, shared database of the world's knowledge". The company, founded by Robert Cook  and Danny Hillis in 2005, was acquired by Google in 2010. Although Metaweb no longer exists as a separate corporate entity, Freebase and its associated website freebase.com]continue to be provided as an open database under Metaweb's original CC-BY licensing terms. In December 2014, Google announced that it would be closing Freebase in 2015, transferring the data to Wikidata.
