On Thursday, a pile of tech-centric legislation was dropped on the New York City Council. When it passed its major open government legislation in 2012, New York’s was the most ambitious law of its kind of any U.S. city. Taken together, these new bills look a lot like an attempt to simultaneously tune up what some see as the jiggly bits on how the city approaches challenges on data, transparency and participatory government. Here, then, is a quick guide to what the bills would do, complete with a short-hand version of why they might be needed, provided by Councilmember Ben Kallos, the Upper East Side lawyer and technologist who, after just five months in office, is sponsoring or cosponsoring each of the bills.
