Data Week 2025, the spring gathering of Europe’s Big Data and Data-Driven AI research and innovation community, took place in Athens, Greece, from 27 to 28 May. With the theme ‘Odyssey of AI: Navigating the Data Seas’, this year’s edition focused on the fundamental elements of data value creation. As usual, DATAMITE was well represented at the event, with a presence in one workshop and as part of the EUDATA+ cluster.
On Tuesday 27, Christos Gizelis from OTE represented DATAMITE at the ‘Monetisation & Governance Across Mobility, Media and Trustworthy Data Sharing‘ session. This session explored methodologies from the DATAMITE project for unlocking the value of data, alongside OTE’s Pluto framework for ensuring robust data governance. Collaboration across trustworthy data sharing (PISTIS), media (FAME), and mobility (MobiSpaces) was highlighted, demonstrating how different sectors are tackling data monetisation and governance while ensuring security, interoperability, and compliance.
On 28 May, the last day of the conference, the EUDATA+ cluster held a session in the plenary room titled ‘EUDATA+: Solutions for Data Trading and Marketplaces (Insight for the Future of AI and Data Spaces)’. The session explored ways to advance the state of AI and data spaces in relation to data trading and pricing solutions. It began with an introduction to the cluster’s evolution and activities, with a focus on the roles of AI and data spaces in the economics of data.
Two keynote presentations examined technological challenges. Professor George Konstantinidis (University of Southampton) and Dr Martin Serrano (University of Galway, DSI-Insight Centre) discussed the challenges involved in developing AI systems that comply with regulations and respect privacy in federated data environments. This was followed by an overview of EUDATA+’s contributions to the Strategic Research, Innovation and Deployment Agenda. This showcased real-world tools for data valuation and highlighted technological gaps and challenges.
Finally, the session featured a panel of experts who provided specialised insights into relevant topics associated with developments and demonstrations. The panel offered the audience valuable insights into the progress of cutting-edge developments and their involvement in EU Horizon Data Projects. This interactive format enabled a rich exchange of perspectives across scientific, technical, and data-business-oriented domains. Speakers included Daniel Saez representing DATAMITE, who discussed ‘Tools for data interoperability in heterogeneous environments’; Fernando Perales representing enRichMyData, who presented ‘Automation and data enrichment workflows for developing data businesses’; Yiannis Verginadis representing ExtremeXP, who presented ‘NFT-based data provenance for large-scale data experiments’; Nikolas Zafeiropoulos representing FAME, who explained ‘Federating assets and commercialising them through data marketplaces’; Radu Prodan, representing Graph-Massivizer, discussed ‘Tools for large-scale data processing and analytics prior to market entry’; Sotiris Koussouris, representing PISTIS, discussed ‘Enabling data monetisation and trading out of the box’; and George Konstantinidis, representing UPCAST, discussed ‘Automating data marketplace operations with user-friendly marketplace plug-ins’.
