description: 'Technische Universität Berlin (TU Berlin) is a public technical research university in Berlin, Germany, and
  a member of the Berlin University Alliance and the TU9 alliance of German institutes of technology. It operates no central
  developer portal, publishes no OpenAPI, AsyncAPI or apis.json of its own, and sells no API product — its programmable footprint
  is the set of standards-based endpoints its own IT units expose on its own hosts, running third-party software. Confirmed
  live and unauthenticated: the DepositOnce institutional repository (DSpace 9, OAI-PMH with 15 metadata formats, a REST/HAL
  API and an OpenSearch description, minting DataCite DOIs under prefix 10.14279); a Shibboleth SAML 2.0 Identity Provider
  whose federation metadata is public (entityID https://ephraim.tu-berlin.de/shibboleth, DFN-AAI); a self-hosted GitLab whose
  REST v4 lists 2,851 public projects without credentials and which is its own OAuth2/OIDC provider; a Matrix homeserver (Synapse)
  with the Client-Server API answering openly; and ISIS, the institutional Moodle, acting as an LTI 1.3 platform with a public
  keyset. Library discovery is an Ex Libris Primo tenant, not TU Berlin engineering. Nothing here is an institution-authored
  contract, and none is claimed.'

x-coverage:
  state: covered
  reason: covered
  detail: 'Every surface below was probed live and unauthenticated on 2026-08-30 from hosts under TU Berlin''s own registrable
    domains (tu.berlin, tu-berlin.de), and the profile is thin by fact rather than by gap. TU Berlin authors no API contract:
    there is no OpenAPI, AsyncAPI, apis.json, llms.txt (404 on www.tu.berlin) or security.txt (403), and no developer portal
    exists to hold one. What it does operate is a set of standards-based deployments of other people''s software — DSpace
    9, Shibboleth, GitLab, Synapse, Moodle — so no openapi/ artifact is saved here: those products'' generic specifications
    belong to their vendors'' own profiles, and saving one under this slug is exactly the misattribution this pipeline exists
    to prevent. Two facts the June 2026 profile got wrong are corrected: the GitLab API is NOT fully gated (public project
    and group listings return 200 unauthenticated, 2,851 public projects) and DepositOnce now runs DSpace 9.4, not 8.1. Library
    discovery was found to be an Ex Libris Primo tenant and is recorded as tenant, not as TU Berlin''s own.'
