Freebase is an open database of the world’s information. "Open" means it's built by the community, for the community — anyone can contribute information, create collections of information to share with others, or build applications that use our API. It also means that the database is freely, openly licensed. Freebase already contains millions of facts in dozens of categories spanning people, locations, books, movies, music, companies, science, sports, and more, and is growing daily, thanks to the efforts of a passionate, global user community.
