European Open Science Cloud (EOSC)

This is a cloud for research data in Europe. Background, policy information, events and publications related to the EOSC

The reports "Prompting an EOSC in practice" and "Turning FAIR into reality" have been published

20 November 2018

In the perspective of the launch of the European Open Science Cloud (EOSC) implementation phase 2018-2020, two important reports are being published by the Commission that constitute major sources of strategic orientations and concrete actions for the new EOSC governance structure:

The report "Prompting an EOSC in Practice" covers on a number of crucial elements of the EOSC, from defining the Minimum Viable Research Data Ecosystem, to establishing the main Rules of Participation; also paying attention to issues as Governance and possible Business Models. The report analyses various aspects of how the EOSC can effectively interlink People, Data, Services and Training, Publications, Projects and Organisations and presents a set of detailed practical recommendations – for implementation, engagement and steering – which will serve as a valuable input for the EOSC governance.

The report "Turning FAIR into reality" describes the broad range of changes required for the implementation of the FAIR data principles. It offers a survey and analysis of what is needed to implement FAIR and it provides a set of concrete recommendations and actions for stakeholders in Europe and beyond. By following a holistic approach, the FAIR Data EG provides a template for key changes in the practice and culture of research and the implementation and normalisation of certain technologies and practices.

Both reports have been produced following a wide and open consultation of the scientific communities in 2018.

Overview of the EOSC Strategic Implementation Roadmap

24 May 2018

After the adoption of the Implementation Roadmap for the European Science Cloud (Staff Working Document SWD(2018) 83) on 14 March 2018 and in order to introduce, illustrate and update the information in this document with the latest developments, the following presentations give an overview of the implementation roadmap.

Please note that the information and views set out in this presentation do not necessarily reflect the official opinion of the European Union and are published for illustrative purposes only.


Implementation Roadmap for the European Open Science Cloud

14 March 2018

The Commission adopted on 14 March 2018 the Implementation Roadmap for the European Science Cloud (PDF icon 987 KB) (SWD(2018)83).

Overall, the document presents the results and available evidence from an extensive and conclusive consultation process that started with the publication of the Communication: European Cloud initiative (COM(2016)178) in April 2016.

The consultation upheld the intervention logic presented in the Communication, to create a fit for purpose pan-European federation of research data infrastructures, with a view to moving from the current fragmentation to a situation where data is easy to store, find, share and re-use.

On the basis of the consultation, the implementation Roadmap gives and overview of six actions lines for the implementation of the EOSC:

a) architecture, b) data, c) services, d) access & interfaces, e) rules and f) governance.

Specifically regarding the latter, the Roadmap presents a governance framework and a governance structure that emerged from the consultation, as a basis for further discussion with Member States. This was foreseen explicitly by the Communication.

The document describes the measures taken under Horizon 2020 Work Programmes to start implementing the EOSC. The financing of the EOSC is secured until 2020 through the Horizon 2020 Work Programme (including €300 million to support the development of the EOSC federating core and open FAIR data pilot), and based on the additional commitments of stakeholders responding to the EOSC Summit Declaration.

The document also specifies the link to the European Data Infrastructure, underpinning high-capacity cloud solutions with super-computing capacity, as well as widening the EOSC by gradually opening up its user base to the public sector and industry.

Today, the document is presented and discussed with the Research Working Party of the Council, with a view of finalising the governance framework for the initiative in the earnest.

Overall, the document will serve as a basis for further consultation with Member States, the European Parliament and other relevant stakeholders on the next steps to take. The EOSC has emerged as a clear policy priority for European research and innovation. It has been strongly supported by the European scientific community in the EOSC Summit and Declaration, by the Council in Council Conclusions (May 2016) and by a European Parliament Resolution (January 2017). It also received favourable opinions from the Economic and Social Committee (September 2016) and from the Committee of the Regions (October 2016).

EOSC Declaration

26 October 2017

Today, the Commission made the EOSC Declaration (PDF icon 118 KB) available to all scientific stakeholders, for their endorsement and commitments to the realisation of the EOSC by 2020.

The Declaration emerged from the EOSC Summit of 12 June, where more than 80 key scientific stakeholders showed a strong sense of commitment, dedication and intellectual rigour with respect to the implementation of the EOSC. We agreed that the EOSC is a truly common European project that we cannot afford to fail.

Overall, response has been plenty, positive and strong. Until today, 70 scientific stakeholders have endorsed the principles of the Declaration. A list of first signatories (PDF icon 341 KB) has already signed up to play a role in the EOSC 'coalition of doers'.

The graphic design, pagination and text of the ESOC Declaration have been minimally adjusted, to reflect the publication of the Research Infrastructures (including e-Infrastructures) part of the Work Programme 2018-2020, developments in HPC, the mid-term review of the Digital Single Market strategy and to correct punctuation and one typo.

We strongly encourage you and your institution to 1) to endorse the principles of the Declaration, and 2) to commit to take some of the specific actions forward.

Many of the signatories, sixty as of today, also committed to one or more actions to implement the principles of the EOSC Declaration. The Action List (PDF icon 54 KB) accompanying the EOSC Declaration already features several commitments.

We urge you to send us your endorsement and commitments, showing your tangible support to our common effort to make the EOSC a reality. You can do so in the way you consider most appropriate, using the dedicated online response survey, or by email (RTD-EOSC@EC.EUROPA.EU). You can always use both options to enclose an official letter, white paper, statement release or any other supporting document your institution is comfortable with.

By endorsing the principles of the Declaration, stakeholders signal their intention to be involved in the making of the EOSC, for instance by taking specific action, by joining the Governance Board, by providing inputs via the annual stakeholder forum, or again by joining consortia to implement the EOSC via Horizon 2020. Necessarily, we must all be on the same sheet to work together in an inclusive, transparent and accountable way. Endorsement of the Declaration is a prerequisite for joint work on the implementation of the initiative.

Commitments by stakeholders are rather envisioned as specific actions relating to stakeholders'' expertise that contribute towards the implementation of one or more points of the EOSC Declaration. Commitments signal the tangible intention of your organization to support the implementation of the different elements of the European Open Science Cloud. By committing, you will help to take forward, expand, clarify and further specify the actions needed to implement the EOSC Declaration.

The DG is currently double-checking each individual stakeholder commitment, with the plan to publish the full list of endorsements and commitments received. This will provide a first complete overview of stakeholder practical support of the initiative.

The Action List is the dynamic part of the Declaration with clear practical utility. It will be discussed at future Stakeholder Forums, it will feed into the EOSC Roadmap and be reviewed by the Governance Board of the EOSC once this is established. We will regularly update the Action List to include any further responses received (every three months).

To help you respond to the Declaration appropriately you can find more details leading to and from the EOSC Declaration (PDF icon 100 KB) .

We strongly encourage all stakeholders not just to agree with the Declaration, but to commit to take some of the specific actions forward.

EOSC Summit 2017

12 June 2017

European Open Science Cloud Summit which took place on 12 June, in Brussels, brought together key players from across Europe, to make the EOSC a reality by 2020. The level of participation was highly representative, including scientific fields, national scientific infrastructures, research funders and ministries of Member States and Associated Countries.

Participants demonstrated a strong sense of commitment towards the implementation of the EOSC. They agreed that the EOSC is a truly common European project which will ensure long term sustainability.



With the adoption of the Digital Single Markets strategy on 6 May 2015, the Commission announced the launch of a cloud for research data – the ‘research open science cloud'. The 'European Open Science Cloud' aims to create a trusted environment for hosting and processing research data to support EU science in its global leading role.

Commissioner Moedas first flagged the initiative at the ERA of Innovation Conference, in June 2015. In a joint blog post, Commissioners Oettinger and Moedas further explained that the initiative 'will combine existing and future data infrastructures, offering secure and seamless access to European researchers for storing, managing and processing data from different sources'.

In his a speech at the Franco-German Conference on Digital (27 October 2015) President Juncker supported a 'nuage européen pour la recherche consacrée à la science ouverte …  Notre ambition est de doter l'Europe de capacités techniques puissantes en termes d'infrastructures, de procès, d'analyse et de stockage des données. Seules les données qui seront traitées de façon performante et sûre créeront de la richesse pour notre société'.

The Commission appointed a High Level Expert Group on the European Open Science Cloud to advise on the scientific services to be provided on the cloud and on its governance structure.

The initiative reinforces Open Science, Open Innovation and Open to the world policies. It will foster best practices of global data findability and accessibility (FAIR data), help researchers get their data skills recognised and rewarded (careers, altmetrics); help address issues of access and copyright (IPR) and data subject privacy; allow easier replicability of results and limit data wastage e.g. of clinical trial data (research integrity); contribute to clarification of the funding model for data generation and preservation, reducing rent-seeking and priming the market for innovative research services e.g. advanced TDM (new business models).

>> Policy context of the EOSC

The European Council and Member States welcomed the initiative in the Conclusions on 'Open, data-intensive and networked research as a driver for faster and wider innovation', adopted at the Competitiveness Council of 28-29 May 2015. Among various conclusions supporting the building blocks of the EOSC, they contain clear indication of support:

6a.  RECOGNISES the importance of long term sustainability of database infrastructure and availability of secure, reliable and high-quality cloud-based services, and UNDERLINES the importance of being able to store and process in Europe research data produced in the Member States; in this context WELCOMES the further development of a European Open Science Cloud that will enable sharing and re-use of research data across disciplines and borders, taking into account relevant legal, security and privacy aspects;

The European Parliament also called on the Commission to move ahead with the initiative. The Parliament adopted a REPORT on 'Towards a Digital Single Market Act', in the plenary vote of 19 January 2016. In point 124, the Committee deals directly and positively with the European Open Science Cloud:

Is concerned that cloud infrastructures for researchers and universities are fragmented; calls on the Commission, in cooperation with all relevant stakeholders, to set up an action plan to lead to the establishment of the European Open Science Cloud by the end of 2016, which should seamlessly integrate existing networks, data and high-performance computing systems and e-infrastructure services across scientific fields, within a framework of shared policies, standards and investments; believes that it should serve as a stimulus to the development of clouds beyond science, to better interconnected innovation centres, start-up ecosystems, and improved cooperation between universities and industry in commercialising technology, in compliance with relevant confidentiality rules, and to facilitating international coordination and cooperation in this field;

Indeed, the initiative is part of Europe’s ambition to support the transition to Open Science in the context of the Digital Single Market; it aims to meet an urgent and specific need of the scientific community to boost data access and re-use and to reduce the cost of data storage and high-performance analysis by pooling existing capacity and by aggregating demand (initially by researchers in the public sector).
