The era of a new generation applications based on open data is far to come. In this context, we observe that OD quality is one of the major threats to achieving the goals of the OD movement. The starting point of this study is the quality of the OD released by the five Constitutional offices of Italy. W3C standards about OD are widely known accepted in Italy by the Italian Digital Agency (AgID). According to the most recent Italian Laws the Public Administration may release OD according to the AgID standards. Our exploratory study aims to assess the quality of such releases and the real implementations of OD. The outcome suggests the need of a drastic improvement in OD quality. Finally we highlight some key quality principles for OD, and propose a roadmap for further research….(more)”
