Freebase

Freebase is a social database about things you know and love. It's an open, shared database of the world's knowledge, a collaborative online collection of structured data harvested from many sources, including individual 'wiki' contribution. Freebase aims to create a global resource which allows people (and machines) to access common information more effectively. It is developed by the American software company Metaweb and has been running publicly since March 2007.

Freebase data is available for use under a Creative Commons “attribution” license, and an API, rdf endpoint, and database dump are provided for programmers.

Metaweb Technologies, Inc. is a US company based in San Francisco that is developing Freebase. The company was founded by Danny Hillis and Robert Cook as a spinoff of Applied Minds in July, 2005, and operated in stealth mode until 2007.
