Founded in 2009 in Berlin by over 20 representatives of political parties, networks and corporations, the Open Data Network promotes open data, open access and open government aiming to put transparency and participation on the political agenda. Its principles are non-biased, independent, non-commercial and centralised. They created OffeneDaten.de, a 'Yellow Pages' for open data from German politics, administration and science. Current projects include Open Data Hackdays, Apps4Democracy and OpenBerlin.net, a prototype for an open city information system.
