The e-Infrastructure Assembly is the structured collaboration of five pan-European digital service providers: OpenAIRE, EGI, EUDAT, GÉANT, and PRACE. Together, they provide and connect local, regional, European and thematic research data centres, data repositories, archives and computing infrastructures as well as universities and other organisations and employ teams of experts with the aim of enabling the advancement of science and innovation. The e-Infrastructures and their members provide an ecosystem of services in which research, innovation, collaboration and coordinated service delivery efforts are aligned with EOSC at the local, national and European level.

For over a decade, they have contributed to the development of EOSC through INFRAEOSC projects and participation in EOSC task forces which guided and aligned the process both contextually and theoretically. Concurrently, Assembly members have strengthened their collaboration with research communities and organisations, focusing on the development, construction and operation of services and underlying infrastructure for the research data life cycle, as well as for the management of the web of FAIR data. These form the basis of the EOSC EU Node, and, since they are readily integrated in the EOSC framework, they are now also available to prospective EOSC Federation nodes.
