DataHub Maastricht (Research IT) Open Source
DataHub is Maastricht University's own research data management service, built and maintained by UM Research IT on an iRODS foundation. Its GitHub organization holds 38 institution-authored repositories — iRODS rulesets, microservices, a PHP iRODS client, CEDAR parsing utilities and SRAM-to-iRODS synchronisation. The Maastricht Data Repository front end at mdr.datahubmaastricht.nl is a single-page application that returns HTTP 200 with an HTML shell for every path probed, including /openapi.json and /api/schema/, so it exposes no public API. The code is the surface; the service is not callable.
