Delft University of Technology
Delft University of Technology (TU Delft) is the largest and oldest public technical university in the Netherlands, ranked #51 in the QS World University Rankings 2025. Its public developer footprint centers on research and library data infrastructure rather than a unified developer portal: the 4TU.ResearchData repository (data.4tu.nl), which TU Delft co-founded and leads, exposes a public REST API (v2/v3, the open-source "djehuty" platform) plus OAI-PMH metadata harvesting; the TU Delft Repository (repository.tudelft.nl) publishes open-access theses and research output with OAI-PMH metadata; and TU Delft operates a NetID/OAuth2 single sign-on identity service. TU Delft historically ran a general institutional API platform at api.tudelft.nl (campus, buildings, courses, education and organisation data) secured with OAuth2, but that platform has been publicly announced as being suspended with no new client registrations accepted, so it is documented here as gated/legacy.
