The European Data Space for Smart Communities (DS4SSCC-DEP) provides tangible technical and non-technical resources for communities to launch a cross-sectorial data-sharing initiative. The project published its blueprint that includes elements for multi-stakeholder governance as well as technical building blocks accompanied by a list of specifications and recommendations, a high-level architecture and a cookbook. Currently, the project receives applications to realise smart city data spaces and ultimately be part of the European data space for communities. Join the session to learn about available resources, the lessons learned, and the remaining challenges.
