EOSC-synergy receives funding from the EC via Horizon 2020 to expand capacities and build capabilities for the European Open Science Cloud (EOSC) by leveraging national digital infrastructures. The project aims to foster greater integration of services and alignment of policies to help lower barriers to EOSC adoption. Key activities include deploying an EOSC-enabled infrastructure, designing strategies for national data repositories, integrating thematic services, and adding training as a fully-fledged EOSC portal component.
