Examples

Worked examples

  • Is an instance

    A pan-European data infrastructure registering its services in the EOSC Marketplace.

  • Is an instance

    A Horizon Europe call requiring grantees to deposit data in an EOSC-onboarded repository.

Counter-examples

Looks similar, but isn't

  • Not an instance

    A single national repository acting alone is not EOSC.

  • Not an instance

    The commercial cloud (AWS, Azure, GCP) is not EOSC.

Editorial commentary

EOSC is governed by the EOSC Association (a Belgian non-profit gathering hundreds of member organisations) under a tri-partite governance with the European Commission and member states. Its core technical artefacts are the EOSC Marketplace (catalogue of FAIR services), the EOSC Federation architecture, and the EOSC Core (authentication, monitoring, accounting, helpdesk). EOSC is the policy frame within which OpenAIRE, PID graph services, and many national infrastructures present themselves as ‘EOSC services’.
