In her TEDx Talk Eileen shows us that every community possesses a treasure: an enormous amount of data, which, if appropriately analysed, may be used to improve traffic organization, energy consumption or scientific research. Open data promotes the idea that access to these data should be freely available to everyone. In her TEDx Talk, Eileen examines where we stand now and what will happen next. Eileen Wagner studied Philosophy at the University of Cambridge and Logic at the University of Amsterdam and is now a team member of Code of Germany and the Prototype Fund, a group of people building tools to analyse open data, making it accessible, understandable and usable. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
