How open data ecosystems are stimulated?

Value creation from open data faces several challenges, among them the risk to be too supply-driven, or the lack of incentives for the re-use. This paper reports an ongoing research program on the stimulation role in an open data ecosystem to mitigate these concerns. First, we present the empirical roots of this role that can be drawn from several initiatives undertaken in different countries and trying to bypass the obstacles faced by potential open data reusers. We discuss the importance of a legal framework inductive to foster innovation and transnationality of the re-use. Then, we introduce the BE-GOOD program which aims to develop new methods to build an open data ecosystem.
