What we can call the first phase of the Open Data is considered ended in our country. Once, speaking of this process, Tim Berners Lee wrote that the path of liberation of the Open Data must start from the top, from the intermediate level and below. And that is what has happened in the last three years in Italy. Now is the time of the second phase: we must imagine and define new targets beyond the principle of transparency’s sake, designed to support the change to a new government in which the citizen, his needs, but also his skills permeate public action. The Open Data Engagement well interprets this need by creating new spaces and tools of collaboration between the various actors.
