Open Food Facts
Open Food Facts (.org) is an open database and associated app and webservice of food products initiated in 2012 by French programmer Stéphane Gigandet.
The database is copylefted under w:Open Database License and the uploaded photos are copylefted under w:Creative Commons license so the database and the photos can be re-used in other services.
It is limited to foodstuffs only by the contract, other will be removed and clearly seeks not to be political.
