How do we improve the usability of research data to move science forward? ‘Good Practices’ and ‘Lessons Learned’ from KIT. The National Research Data Infrastructure (NFDI) will continue to be established so that research data can become scientifically widely usable in the sense of data treasures with social added value, also with the goal of connectivity, e.g. to the European Research Cloud (European Open Science Cloud, EOSC). The summer event is aimed at researchers from all departments and institutes of the University of Hildesheim, as well as interested parties from the global RDM community (libraries, data centers, data protection officers, etc.), as well as for all those who are interested in our topics (Citizen Science) .
