The EOSC Symposium 2019 represented a fundamental milestone in the EOSC roadmap. It was co-organised by the Secretariat and the main ICT eInfrastructures initiatives, namely, EOSC-hub, GEANT, OpenAIRE and PRACE in collaboration with the EOSC Governance Board, Executive Board and its Working Groups. The event saw three inspiring days during which all stakeholders contributed to discussions on the implementation of the EOSC. Taking place from the 26th to the 28th of November 2019, in Budapest, Hungary, the EOSC Symposium brought together the shakers and makers in the growing world of EOSC, providing answers to some of the most frequently asked questions about the European Open Science Cloud. We have collected the highlights from these intense and stimulating days in a magazine for the whole EOSC community.
