I've just finished spending two days at a mini-retreat on open government data organized by Carl Malamud of Public.Resource.Org, hosted by Tim O'Reilly of O'Reilly Media and funded by the Sunlight Foundation, Google and Yahoo!. The purpose of the meeting was to gather a bunch of folks from both the public and private sectors who are working on everything from pro-democracy websites to hyper-local news startups to see if we could draft some common principles for data and open government, and also to deepen connections and collaboration among a powerfully creative group of individuals and projects. (Full disclosure: I was there in my consulting role as a senior technology adviser to Sunlight, but this was another of those fortuitous events where I get to where all my hats as PdF editor, open government activist, and Sunlight consultant at once.)
