  Trinity College Dublin (the University of Dublin) is Ireland's oldest university,
  founded in 1592, and ranked #98 in the QS World University Rankings 2025. Its public
  developer/API footprint is not organized around a dedicated developer portal or a
  documented open-API program; instead it is expressed through standards-based scholarly
  infrastructure. The Library of Trinity College Dublin runs TARA (Trinity's Access to
  Research Archive), a DSpace institutional repository that exposes an OAI-PMH metadata
  interface, and Digital Collections, a Hyrax/Samvera platform that serves IIIF
  Presentation manifests for digitised manuscripts including the Book of Kells. Both are
  publicly reachable in a browser but currently sit behind bot-mitigation (Cloudflare /
  reCAPTCHA), so they are not openly machine-callable without interactive access. Federated
  identity is provided through HEAnet's Edugate (eduGAIN) SAML federation rather than a
  public OAuth/OpenID developer API.

    name: TARA OAI-PMH (Trinity's Access to Research Archive)
    description: >-
      TARA is Trinity College Dublin's open-access institutional repository, built on
      DSpace. It exposes an OAI-PMH (Open Archives Initiative Protocol for Metadata
      Harvesting) interface for harvesting Dublin Core and other metadata about theses,
      articles, and other research outputs. The repository is harvested by national and
      European aggregators (e.g. RIAN, OpenAIRE). The endpoint is reachable interactively
      but is currently fronted by bot-mitigation that returns HTTP 403 to unattended
      programmatic clients.

    description: >-
      Digital Collections is the Library of Trinity College Dublin's Hyrax/Samvera-based
      digital asset repository, providing access to digitised manuscripts and collections
      including the Book of Kells. The platform serves IIIF (International Image
      Interoperability Framework) Presentation manifests per work, enabling use in
      IIIF-compatible viewers. Manifests are reachable interactively in a browser but the
      site is fronted by reCAPTCHA bot-mitigation that blocks unattended automated requests.
