EUDAT-B2FIND: A FAIR-friendly and Interdisciplinary Data Catalogue
•
1 like•222 views
Presentation by Heinrich Widmann, DKRZ The European Data Infrastructure (EUDAT) project establishes a pan-European e-infrastructure supporting multiple and diverse research communities in their research data management. This Collaborative Data Infrastructure (CDI) is based on the FAIR principles and implements community-driven and generic services to tackle the specific challenges of international and interdisciplinary research data management. The EUDAT metadata service B2FIND plays a central role in this context as a repository and a search portal for the diverse metadata collected from heterogeneous sources. For this we built up a comprehensive joint metadata catalogue and an open data discovery portal and offer support for new communities interested in publishing their data within EUDAT.

- 32. EUDAT and the B2 services Guidelines and Concepts FAIR Approach of EUDAT-B2FIND Outlook and Summary Challenges Lessons learned Next steps Conclusions Links and Contact Lessons learned Less is sometimes more : Catalogue with a manageable amount of high quality metadata instead a mess of millions of entries Talk more to community representatives and researchers (at best already in the phase of generation of the metadata) Low(er) barrier for communities to get contact, documentation and support from EUDAT 21 / 24

EUDAT and the B2 services Guidelines and Concepts FAIR Approach of EUDAT-B2FIND Outlook and Summary Challenges Lessons learned Next steps Conclusions Links and Contact Conclusions EUDAT-B2FIND established an operative service based on agreed standards and guidelines as the FAIR principles, provides a discovery portal with powerful search functionalities and is based on a unique catalogue of research data , combining many heterogeneous and cross-discipline sources Improved interoperability is achieved by homogenisation to a common metadata schema Further efforts are made to address the demands of the communities and data projects, to adapt the system for future challenges 23 / 24
