On January 21-22, 2025, the FITTER-EU consortium convened at the Complutense University of Madrid for a highly productive in-person meeting. This event provided an essential platform for partners to discuss project progress, refine methodologies, and align on key technical developments. One of the core areas of discussion was Work Package 5 (WP5), which focuses on the technical backbone of the FITTER-EU platform. WP5 hosted dedicated sessions aimed at structuring the next phase of development, ensuring data integration, and refining the platform’s co-creation activities. AITEC played a pivotal role in the WP5 sessions, providing expertise in data integration and technical development. Their contributions were crucial in defining the roadmap for platform co-creation, ensuring that the FITTER-EU platform remains robust, scalable, and impactful for policymakers and researchers.
