The Athena Research Center hosted the final plenary meeting of the DataBri-X project in Athens on 19 - 20 September 2025, followed by a successful final project review on 14 October. The project, which is coordinated by the Athena Research Center and implemented through its Information Management Systems Institute (IMSI / Athena), has made a significant contribution to the development of sovereign and interoperable European data spaces through a comprehensive suite of technological tools and infrastructures.

 

Before that DataBri-X partners Athena, WKD, SIE and SWC/Graphwise participated in SEMANTiCS 2025, the 21st International Conference on Semantic Systems held in Vienna, Austria. At the heart of DataBri-X presence a demo paper by Athena Research Center titled "Semantically-Enabled Data Spaces for Intelligent Data Asset Discovery" introduced KNOWDS, a system that extends Data Spaces with semantic search capabilities, enabling intelligent data asset discovery through relevance graphs and advanced query mechanisms. This innovation supports the vision of Gaia-X and the International Data Spaces (IDS), while aligning with the DataBri-X mission of fostering trustworthy AI through data spaces.

 

DataBri-X successfully concluded its public webinar series with a milestone event titled “Empowering European Data Spaces: The final DataBri-X toolbox unveiled”. Held online on July 22, the webinar marked the official release of the complete DataBri-X Toolbox, a modular and interoperable suite of over 25 tools designed to support the development of sovereign, scalable, standards-aligned European data spaces. Moderated by Martin Kaltenboeck (SWC/Graphwise), the session featured expert presentations from key project contributors, including coordinator Stelios Sartzetakis (IMSI / Athena), Javad Chamanara (TIB), Robert David (SWC/Graphwise), and Kostas Oikonomou (NOVA). The toolbox architecture, which is built around JenPlane, a workflow and governance engine, emphasizes policy enforcement, monitoring, and optimization, with support for OpenAPI 3.0, Docker deployment, and compatibility with IDS-RAM and the European Language Grid.

 

The webinar also showcased results from three live pilot deployments across telecom, energy, and legal domains. In Athens, the Telecom Data Space piloted tools for customer segmentation and network forecasting. Vienna’s Energy Data Space enabled smart community energy simulations, while the Legal Data Space in Huerth focused on document annotation and legal knowledge graph construction. These pilots validated the toolbox’s cross-sector applicability and confirmed its technical robustness and real-world readiness, setting the stage for broader adoption in the evolving European data ecosystem.
