D10.5 “Final Report on Implementation Activities” describes the work towards making the RIs in the solid Earth subdomain FAIR in terms of FAIRness of the assets and EOSC-interoperability. In this deliverable we therefore describe for each WP10 task, the work done to address the gaps identified by Deliverable “D10.2 Roadmap for implementation of FAIR concepts”, prioritised and harmonised in D10.3 “D10.3 Report on coordination, prioritisation, and harmonisation in the Solid Earth Subdomain”.
