This poster was presented at the DH 2025 held from July 14-18, 2025, at NOVA-FCSH in Lisbon and highlighted early findings from the ATRIUM project, a European Commission-funded initiative (2024–2027). The poster focuses on ATRIUM’s community-driven approach to improving services and training, drawing on insights from a Europe-wide Researchers’ Survey and the first Researcher Forum. The survey, with over 280 responses from 25+ countries, highlights skill gaps in areas like Open Science and FAIR principles, informing the development of the ATRIUM Curriculum. The Researcher Forum, held in Poznan, Poland, piloted collaborative usability testing of the GoTriple platform, exemplifying how researcher feedback directly informs infrastructure refinement. The poster demonstrates how ATRIUM integrates community input to co-design impactful, needs-based training and services, and provides access to related statistics and resources for reuse.
