  University College Dublin (UCD) is Ireland's largest university and ranks
  #126 in the QS World University Rankings 2025. Its public, machine-readable
  footprint is concentrated in library and cultural-heritage systems rather
  than a central developer portal: the UCD Digital Library exposes IIIF Image
  and Presentation APIs plus a Geospatial Data API and unAPI endpoint, the
  DSpace-based Research Repository UCD offers OAI-PMH harvesting and a REST
  API, and the National Folklore Collection held at UCD is served via the
  Dúchas API. There is no unified, self-service institutional API program;
  most administrative and identity systems are gated behind institutional
  affiliation.

    description: >-
      The UCD Digital Library Data Services expose IIIF Image API 2.0 and
      Presentation API 2.0 endpoints serving images and manifests for digitized
      cultural-heritage objects and collections, consumable by IIIF clients
      such as Mirador. Objects are addressed by namespaced internal identifiers
      (e.g. ivrla:31286).
