In the Free City of Hamburg, which is one of 16 German states, a coalition of hackers, activists and other players of civil society have drafted the most revolutionary Freedom of information law in the world.
The law obliges the state to proactively publish all important public information (such as contracts, studies, construction permits) in an OpenData format on the Internet. After the start of a referendum campaign, the law was passed unanimously by the state parliament in June 2012 to avoid a public vote on it.
