Abstract The Future Circular Collider (FCC) integrated programme is conceived as a long-term, open, and internationally shared research infrastructure, that combines a high-luminosity electron–positron collider (FCC-ee) with a subsequent energy-frontier proton–proton collider (FCC-hh) in a common 91-km-scale tunnel. Beyond its physics case, the programme is structured around research-infrastructure requirements: staged delivery and risk management across decades, broad user access, and sustainable operations supported by modern digital services. In particular, alignment with the FAIR data principles and interoperability with federated e-infrastructures such as the European Open Science Cloud (EOSC) provide a pragmatic route to maximise reuse of data and software outputs across communities.
