The following press release is from EOSC and is published here with kind permission.

BRUSSELS—Today at the EOSC Symposium, the European Open Science Cloud (EOSC) took a major step toward its consolidation as Europe’s research and innovation data space. The 14 coordinators of the EOSC Federation’s first wave of EOSC Nodes joined EOSC Association (EOSC-A) President Klaus Tochtermann and Co-Chair of the EOSC Federation’s Build-up Group Bob Jones on the stage to introduce the EOSC Federation’s Memorandum of Understanding (MoU).

Champions of the community

The agreement, to be signed by 13 candidate EOSC Nodes and EOSC-A, marks the culmination of eight months of hard work and coordination carried out on an in-kind basis by the dozens of European organisations standing behind the nodes. As champions of the European research community, these organisations—including Research Infrastructures, e-Infrastructures, and research-performing organisations—have established the technical and organisational foundations for the future of Open Science in Europe.

The undertaking is meanwhile being steered by the EOSC Tripartite Governance, composed of the European Commission (EC), Member States of the European Union and Associated Countries to Horizon Europe, and EOSC-A. The Commission owns and operates the EOSC EU Node, which is invited to be a signatory of the Memorandum, and Director-General of the EC’s Directorate General for Research and Innovation (DG RTD) Marc Lemaître was on hand for the event, having presented the Symposium’s opening speech.

The Federation is the future

The EOSC Federation MoU marks a decisive step towards a truly borderless European research ecosystem. It advances Open Science while reinforcing European data sovereignty and strengthening Europe’s competitiveness in the global knowledge economy.

The MoU ceremony served to close out a day dedicated to high-level discussions between European policy-makers and research community stakeholders on the future of EOSC. These were placed in the context of the afternoon’s debut of the EOSC Federation and a showcase of its scientific impact.

Joining Lemaître on the Symposium’s opening day were Robbert Dijkgraaf, President-elect of the International Science Council, Maria Leptin, President of the European Research Council, and Mattias Björnmalm, Secretary General of EOSC-A founding member CESAER, together with DG RTD’s ERA & Innovation Acting Director Jean-David Malo, EOSC Steering Board Co-Chair Volker Beckmann from the French ministry of higher education, research and space, and Tochtermann.

Said Tochtermann, “This moment shows what shared stewardship of Europe’s research ecosystem can achieve. The EOSC Federation will not only connect technical infrastructures, but also people and principles in a corresponding social infrastructure. The MoU gives us the operational framework to test, integrate, and scale services across borders—to lay the groundwork for a sustainable, interoperable European research data commons.”

The backbone of Europe’s digital strategy

The Memorandum establishes a shared operational and interim governing framework for the piloting phase of the Federation. Once brought into production, the EOSC Federation of nodes will serve as the backbone of Europe’s interoperable, open, and trusted digital infrastructure enabling researchers and innovators to seamlessly access high-quality data and tools across disciplines and national borders.

EOSC and the EOSC Federation have been called out on several occasions in 2025 as a key structural element for the advancement of European competitiveness in research and innovation, including:

  • In the European Council’s recommendations on the ERA Policy Agenda, where EOSC is reaffirmed as a key element of Priority Area 1: Deepening a truly functioning internal market for knowledge;
  • In September’s European Strategy on Research and Technology Infrastructures, where the EC pledges to develop actions in support of “aligning and coordinating investments across Europe for trusted and secure storage, processing and sharing of critical data including through EOSC”; and
  • In the recently released strategy for AI in Science, where the EOSC Federation is identified as a critical enabler of AI in science by providing access to interoperable and reusable datasets.

As an intended signatory of the MoU, and an integral part of the first wave of the EOSC Federation of interoperable nodes, the German National Research Data Infrastructure (NFDI) aims to bring the full measure of its scientific services to bear on the ambitious goals of the Federation. Participation in the Federation’s first wave represents a self-funded commitment by NFDI to build up the trust and shared practices that will anchor the EOSC Federation as an essential research infrastructure reaching across disciplines and borders in Europe.

Calls to grow the EOSC Federation

The process to expand the EOSC Federation will begin immediately, as the EOSC Symposium’s first day also served as the launching pad for an enrolment call for the next wave of future EOSC Nodes by the EOSC Tripartite Governance.

Announced concurrently were two calls from the EOSC-A-coordinated EOSC Gravity project for preparatory and inter-project grants in support of the Tripartite’s expansion of the Federation.

As the EOSC Federation grows, the non-binding interim agreement represented by today’s MoU ceremony will pave the way for a future binding agreement that would legally establish an operational EOSC Federation.

5-year anniversary of the NFDI association: A brief journey through time in 5 images

Five years ago, on 12 October 2020, the German federal and state governments jointly founded the association Nationale Forschungsdateninfrastruktur (NFDI) e.V. in Hannover. More than 300 institutions are now members, and the association continues to grow. The members are united by a common vision: data as a shared good for excellent research, organised by the scientific community in Germany.
To celebrate the association’s 5th anniversary, we would like to take a brief journey through time in 5 pictures. The photos illustrate how NFDI has transformed throughout its development phase into a strong network.

RDM in Action: Highlights oft CoRDI 2025

Almost 700 people attended the Conference on Research Data Infrastructure (CoRDI) 2025 at RWTH Aachen University. The three-day conference, held from 26 to 28 August at C.A.R.L. (Central Auditorium for Research and Learning), focused on making better use of research data and the resulting added value for science and society. The motto ‘RDM (Research Data Management) in Action’ was reflected in all presentations, discussions and posters.
