New York City is hosting its third annual BigApps conference this year: BigApps 3.0. Build an application from any combination of 750 New York City data sets that describe everything from political campaign contributions to bicycle rack locations. There are more than a dozen different prize categories and $50,000 of cash prizes to be distributed. For the first time in a BigApps contest, New York City has its own API and the contest also encourages using APIs of NYC companies, including the Foursquare API and Etsy API.
