These resources address the creation of data spaces and key design principles to promote data sovereignty and cross-sector data sharing in Europe. The document details how these data spaces can work together through a common “soft infrastructure” and governance structure, technical and administrative building blocks, business models and examples of sectoral implementation. It also highlights the role of the European Data Act, Data Governance Act and the proposed strategic and operational governance bodies for the implementation of this infrastructure. In conclusion, the resources call for a coordinated approach and long-term investment to achieve Europe’s leadership in the data economy.
