The FAIRCORE4EOSC project focuses on the development and realisation of core components for the European Open Science Cloud (EOSC). FAIRCORE4EOSC supports a FAIR EOSC and addresses gaps identified in the Strategic Research and Innovation Agenda (SRIA). Leveraging existing technologies and services, the project will develop nine new EOSC-Core components aimed to improve the discoverability and interoperability of an increased amount of research outputs.
