The primary focus of work package four in FAIRsFAIR is (trusted) repositories that enable the curation of (FAIR) objects. But to be integrated into an operational European Open Science Cloud (EOSC) a wider vision of FAIR ecosystem dependencies and interconnections is required. Data users and stewards of all kinds must be empowered to find, store and access data and metadata designed for interoperability and reuse. This draft presents a vision for the FAIR ecosystem components required to ensure FAIRness across the full data lifecycle.
