The Science Mesh enables researchers, educators, data curators and analysts to retain control over their remote or domestic datasets, while becoming FAIR compatible and integrated with the European Open Science Cloud (EOSC) at the same time. This will offer researchers opportunities to assemble an efficient, reliable, collaborative and transparent research tool chain. Our target stakeholders will be able to directly access the service provided by Science Mesh from easy-to-use interfaces and discover the different functionalities. The added-value for the stakeholders of CS3MESH4EOSC relies on the possibility for them to contribute in developing application plugins or easily set-up federations in their own scope and develop their own activities on top of them.
