Within the DEPLOYTOUR project, a structured evaluation campaign is being conducted to  assess a broad set of European initiatives related to data sharing. The first evaluation round focuses on determining which  of them can be classified as fully fledged Data Spaces, versus earlier-stage forms such as data-sharing initiatives or collaborative platforms.

The evaluation approach follows the Data Spaces Support Centre (DSSC) framing of Data Spaces as interoperable ecosystems grounded in governance, trust, interoperability, and enabling services. Therefore, this evaluation provides a consistent basis to: (i) classify initiatives using the same criteria and thresholds, and (ii) summarize the overall landscape in a way that is useful for reporting and dissemination.
