inAfter three years of intense work on AD4GD and ongoing, close collaboration with our sister projects (B-Cubed, FAIRiCUBE, USAGE), what better way to share the knowledge we’ve gained with the rest of the world than through an in-person event?

The event, “Three Years of Experience Developing Green Deal Data Spaces” , aimed to distill all this expertise into a day and a half packed with 26 sessions, ranging from keynotes and demonstrations to hands-on workshops and discussion panels.

The goal of the event was to bring together researchers, policymakers, and technical experts to:

• Demonstrate innovative tools for data interoperability and governance.

• Share lessons learned across project implementations.

• Launch a joint Policy Brief to guide the future development of the Green Deal Data Space in Europe.

We would like to express our sincere gratitude to VRIS who hosted us at their facilities at the Ares Tower in Vienna. Their warm welcome and excellent support were instrumental in making this gathering a success. 

All sessions were recorded and are publicly available on YouTube: 

The event began with a welcome and an introduction to our four European sister projects contributing to the Green Deal Data Space. The opening sessions laid the conceptual foundations, highlighting the importance of semantic interoperability and the role of the EuroGEO group in shaping the GDDS. Throughout the day, a series of 13 live demonstrations showcased key technologies developed by the sister projects in support of this initiative. These included information models for semantic interoperability, the use of Eclipse data connectors in the GDDS, or the creation of city-specific data spaces using open-source software components. Practical workshops were also held on data governance, metadata management, and using tools like TAPIS for data negotiation and access.

The second day focused on sharing lessons learned and discussing challenges and opportunities in the future implementation of the Green Deal Data Space. Expert panels addressed topics such as data harmonization, semantic interoperability, and metadata management. The day concluded with the presentation of a joint Policy Brief, prepared by the four projects, offering recommendations to guide the future development of the GDDS in Europe. This document emphasizes recommendations in five domains: data harmonization, semantic interoperability, metadata, data exchange and inclusive governance.
