This document presents the sustainability plan of the results from FAIR-EASE. Sustainability consists of several ingredients including technical, financial, political and promotional aspects. This is also grounded in a rich, federated and evolving ecosystem, participates in the building of the European Open Science Cloud, fosters close collaborations with other EOSC and non-EOSC related projects, and participates in a wide variety of European policies. The recent organisation of EOSC into a Federation of Nodes has been taken into consideration as a way to guarantee a long term potential sustainability for some of the FAIR-EASE results. It is noteworthy that if all FAIR-EASE results have reached a technological readiness level of 7, increasing this level necessitates another economic model (from project funding to recurrent funding scheme) where sustained funding is ensured. This remains the bottleneck of the sustainability plan. As FAIR-EASE results are interrelated, levels from upstream results (access to data services, analyses tools) impacts downstream results (services to end-users).
