Main elements of the EPOS Architecture: National Research Infrastructures (NRI), Thematic Core Services (TCS), Integrated Core Services Centralized and Distributed (ICS-C & ICS-D) form the EPOS functional architecture, coordinated by EPOS ERIC, and designed to ensure the EPOS data and service provision. The Integrated Core Services Central Hub (ICS-C) and the Executive and Coordination Office (ECO) belong to the EPOS ERIC legal subject.

The EPOS Data Portal. Managing Data provision through the ICS-C system also required addressing the topics of policies and sustainability, detailed later in this paper.

Figure 3
The ‘shape-up’ method reviewed to fit the research context. It envisages four workshops (WS) per year, followed by four development cycles.
Table I
Components of the Data Management Plan Guidelines for Federated Research Infrastructures. The table shows the Guidelines components suggested by the Horizon Europe Guidelines on FAIR Data Management, together with the proposed extension including additional components dedicated specifically to Data Management in the context of Distributed, Federated Research Infrastructures as stemming from the experience of EPOS.
| DMP COMPONENT | DESCRIPTION |
|---|---|
| Components from Horizon Europe guidelines | |
| Data Summary | Brief description of the data, type of data and its coverage must be provided. Data formats, origins, total expected size of datasets and type of users should also be outlined |
| FAIR Data | Detailed description of how the FAIR principles are addressed and taken into account |
| Other Research Outputs | Plan for the management of other research outputs, digital or physical, that may be generated or re-used throughout the initiative in a FAIR way |
| Allocation of Resources | Description of resources to make data FAIR and to ensure its sustainability, as well as resources needed to deliver the plan |
| Data Security | Description of data recovery as well as secure storage and transfer of sensitive data |
| Ethical Aspects | Description of ethical or legal issues that can have an impact on data sharing |
| Other Issues | Additional information about other procedures for data management currently in place |
| Extended components for distributed, Federated Research Infrastructures | |
| Community Interaction | Description of the processes to manage the community of distributed resource providers in order to ensure federated provision of distributed resources |
| Governance | Description of the underlying governance at the basis of the federated resource provision |
| Policies | Addressing the policies that should be in place for supporting the governance and ensuring that resources (e.g., Datasets) combination, propagation and exchange is done appropriately and with well-defined responsibilities |
| Sustainability | Description of the legal, scientific and financial aspects that ensure the capacity to grant long-term (sustainable) access to data and products, and the capacity to do so under a common federated framework. |
