4TU.ResearchData Dutch Research Data Repository for Science, Engineering and Design

Overview

4TU.ResearchData is an international research data repository specializing in science, engineering, and design. Operated as part of the 4TU.Federation—a collaboration among the four Dutch technical universities (TU Delft, Eindhoven University of Technology, University of Twente, and Wageningen University & Research)—the repository offers long-term, trustworthy storage and open access to scientific datasets from researchers worldwide.

History and Founding

The repository was founded in 2008 as an initiative of the three Dutch universities of technology (TU Delft, TU Eindhoven, and University of Twente), then operating as 3TU.Datacentrum. The repository went fully operational in 2010. When Wageningen University & Research joined the 4TU.Federation in May 2016, the consortium was renamed 4TU and the repository became 4TU.ResearchData (formerly also known as 4TU.Centre for Research Data).

Collections and Holdings

The repository hosts datasets spanning engineering, applied sciences, and design disciplines. Holdings include numerical simulation data, experimental measurements, audio recordings, geospatial datasets, and software code repositories. Datasets are stored for a minimum of 15 years and receive Digital Object Identifiers (DOIs) to facilitate citation and discovery. As of the mid-2020s, the archive holds tens of thousands of datasets totalling many terabytes of research data. All metadata is published under a CC0 licence and is indexed in international portals including OpenAIRE CONNECT and the Clarivate Data Citation Index.

Access and Usage

Any researcher, anywhere in the world, may deposit or access data via the repository website at data.4tu.nl. Researchers affiliated with the 4TU universities can deposit up to 100 GB per year free of charge; larger deposits are subject to a modest fee. The platform supports integration with GitHub, GitLab, and Bitbucket, allowing software releases to receive persistent DOIs. The repository has obtained the CoreTrustSeal certification, confirming its status as a trusted digital repository.

Standards and Infrastructure

4TU.ResearchData is built on the Figshare infrastructure and follows the FAIR data principles (Findable, Accessible, Interoperable, Reusable). Metadata is provided in DataCite, Dublin Core, and CF (Climate and Forecast) conventions. The repository also provides an OAI-PMH endpoint for metadata harvesting.
