The overarching goal of ENVRI-FAIR is that all participating research infrastructures (RIs) will improve their FAIRness and become ready for connection of their data repositories and services to the European Open Science Cloud (EOSC). Deliverable 9.1 has reported on the roadmap of the RIs in the marine subdomain towards improving their FAIRness. It presented the approach of using FAIR questionnaires (together with WP5) to identify the strengths and weaknesses of each RI and a first indicative set of activities to improve identified weaknesses or gaps. After formulation in Deliverable D9.2 of implementation plans for mitigating these gaps during the next phase of the ENVRI-FAIR project, the RIs from the marine subdomain have specified in Deliverable D9.3 the technical services and interfaces to be implemented at RI level and have undertaken the implementation. The RI services will be demonstrated in D9.4 (M27) and will be operational for EOSC operations in D9.5 (M36). The present deliverable D9.6 is linked to Task 9.8 going from M24 to M48 and aiming to demonstrate the marine subdomain FAIRness. Here the This document D9.6 describes the technical specifications that will be necessary for the Marine EOV product Version 1 and Version 2 to run in 2021 and 2022.
