Abstract
FAIRfest: A Festival of FAIR Solutions in the European Open Science LandscapeFAIR-IMPACT and FAIRCORE4EOSC partners were pleased to invite the broad European research community to FAIRfest, a festival that celebrated advancements in FAIR (Findable, Accessible, Interoperable, and Reusable) solutions within the European Open Science research landscape. Held in The Hague (The Netherlands) alongside the 19th International Digital Curation Conference (IDCC25), the event brought together European and international participants to explore the latest achievements in FAIR: Persistent Identifiers and Knowledge Graphs for Findability, Semantic Artefacts for Accessibility, technical and legal aspects for Interoperability, and certification, metrics, and guidelines for Reusability. The festival featured a vibrant Marketplace where adopters and implementers showcased FAIR-enabling solutions, tools, methodologies, and practices through stands, coffee tables, and posters. Attendees engaged directly with experts, asked questions, and learned from those already applying FAIR in real research contexts. Demonstrations of FAIRCORE4EOSC components were presented, and participants heard implementation stories from teams supported by the FAIR-IMPACT programme. The event also offered opportunities to meet FAIR Champions, Ambassadors, and interoperability specialists, creating a dynamic environment for exchange and collaboration.
