  13. 13. • A pan-European initiative building a sustainable cross-disciplinary and cross-national data infrastructure providing a set of shared services for accessing and preserving research data • Close collaboration with research communities to optimally support their data management needs and deliver the appropriate technical services EUDAT - European Data Infrastructure
  14. 14. A truly pan-European Infrastructure EUDAT offers common data services, supporting multiple research communities as well as individuals, through a geographically distributed, resilient network of 36 European organisations Our vision is to enable European researchers and practitioners from any research discipline to preserve, find, access, and process data in a trusted environment, as part of a Collaborative Data Infrastructure
  15. 15. EUDAT Vision & Mission ● Vision: Data is shared and preserved across borders and disciplines thereby enhancing the value and quality of research at large. ● Mission: To enable data stewardship within and between European Research Communities through a Collaborative Data Infrastructure, a common model and service infrastructure for managing data spanning all European research data centres and community data repositories.
  16. 16. What is the EUDAT CDI? • The EUDAT CDI is a collaboration between Service Providers and Research Communities working as part of a common framework for developing and operating an interoperable layer of common data services • Generic Service Providers have regional, organisational or national mandates to support scientific research, usually from different disciplines. • Thematic Service Providers are (discipline-specific) organisations mandated to support a well-defined scientific community or group of users.
