description: 'Trinity College Dublin, the University of Dublin, founded in 1592, is Ireland''s oldest university and a legal
  deposit library for Ireland and the United Kingdom since 1801. Trinity operates no public developer portal, publishes no
  OpenAPI, issues no API keys and runs no documented open-API programme — and this profile says so rather than padding the
  gap. What Trinity does operate, and what is recorded here, is standards-based scholarly and identity infrastructure: a self-hosted
  Shibboleth Identity Provider on its own domain (idp.tcd.ie, scope tcd.ie) registered in HEAnet''s Edugate federation and
  exported to eduGAIN; a Microsoft Entra ID tenant with live OIDC discovery; an OpenSearch 1.1 description document authored
  by Trinity''s own Digital and Web team; DataCite consortium membership with five prefixes and 16,031 DOIs across five registered
  repositories; and Crossref membership. Its two flagship repositories — TARA (DSpace) and Digital Collections (Hyrax/Samvera,
  home of the Book of Kells) — sit on Trinity''s own hosts but are fronted by Cloudflare and F5 bot-mitigation that returns
  a challenge to every unattended client, so they are live but not machine-callable. eDeposit Ireland, the national legal-deposit
  repository Trinity Library administers, is the one repository that answers a harvester, and it does so as a tenant on Atmire''s
  Open Repository platform rather than as Trinity''s own engineering.'

  detail: 'Trinity''s two institution-operated repository surfaces — TARA at www.tara.tcd.ie and Digital Collections at digitalcollections.tcd.ie
    — are both reachable in a browser and both refuse unattended clients. TARA returns a Cloudflare 403 interstitial on every
    path, including /oai/request and /server/oai/request. Digital Collections returns a soft-200 reCAPTCHA page from an F5
    Distributed Cloud edge on every path, including /robots.txt and IIIF manifest URLs, so the 200 is not evidence of a readable
    surface. Neither is dead and neither is an authentication wall; both are bot mitigation. Everything reachable WAS read:
    the Shibboleth IdP metadata, the Entra ID OIDC and SAML metadata, the OpenSearch descriptor, the eDeposit Ireland OAI-PMH
    Identify/ListMetadataFormats/ListSets responses and the DSpace REST root, and the DataCite, Crossref and ROR registry
    records. Beyond that there is simply nothing to find: api.tcd.ie, data.tcd.ie and developer.tcd.ie do not resolve, and
    www.tcd.ie/llms.txt returns 404.'
