Open Knowledge Foundation is a global, non-profit network that promotes and shares information at no charge, including both content and data. It was founded by Rufus Pollock on 20 May 2004 and launched on 24 May 2004 in Cambridge, UK. It is incorporated in England and Wales as a company limited by guarantee. 

Their mission is to create a more open world – a world where all non-personal information is open, free for everyone to use, build on and share; and creators and innovators are fairly recognised and rewarded.
