This presentation discusses the importance of long-term preservation and access to research data. It notes that current research data management faces risks like loss of data and metadata over time. Preserving data has value for verification, knowledge transfer, and continuing research. The 3TU.Datacentrum project aims to build a repository for research data from three Dutch universities to enable long-term access. It is collecting and preserving datasets and providing data management services and advice to data producers. Workshops with data producers found support for the repository but also concerns about confidentiality, resources, and responsibilities.
