description: 'TU Wien (Vienna University of Technology) is Austria''s largest science and technology university, founded in
  1815, with more than 30,000 students across eight faculties. It operates no central developer portal, publishes no API key
  issuance page and offers no unified developer credential, and most of what looks like a TU Wien API is a product it bought
  rather than built. What it does operate is real and unusually varied for the cohort: a self-hosted InvenioRDM research-data
  repository whose REST API answers anonymously, two live OAI-PMH endpoints, a DSpace-CRIS institutional repository, the TISS
  student-information REST API (versioned, structured errors, documentation behind TU Wien SSO), a SAML 2.0 identity provider
  registered in the ACOnet/eduID.at federation and interfederated into eduGAIN, and — the one genuinely engineered contract
  — the FUNDify funding API, written and maintained by TU Wien Campus Software Development for the Austrian RIS Synergy network
  the university led. Its library discovery layer is a tenant surface on the OBVSG consortium''s Ex Libris Primo platform,
  not TU Wien engineering. Conformance is concentrated in research infrastructure: OAI-PMH 2.0, DataCite, ORCID and SAML are
  all verified live; SCIM, LTI, OneRoster, Ed-Fi, Caliper and QTI are absent.'

  note: Re-profiled under the university contract's operator axis. The June 2026 profile recorded three surfaces and no operator
    on any of them; this run settled the operator for nine, found four surfaces the first pass missed (TISS, FUNDify, the
    RIS Synergy OIDC realm and the SAML identity provider), and re-labelled the library catalogue as a tenant relationship.

    runs for the ARISnet consortium at fundify.arisnet.ac.at; TU Wien led the RIS Synergy project that defined the standard.
  description: TU Wien's own OpenAPI-described contract, and the only one in this repository. FUNDify publishes Austrian funding
    programmes and calls and lets institutions annotate them for their own researchers, implementing the RIS Synergy national
    Funding endpoint. Four GET operations, 32 object schemas. Anonymous calls return 401; the contract itself documents no
    401 and no error body, which rules/tu-wien-spectral.yml flags.

x-coverage:
  state: covered
  reason: covered
  detail: 'TU Wien has eight institution-operated machine surfaces and one tenant relationship, all probed live on 2026-08-30.
    Three read anonymously (the InvenioRDM REST API and both OAI-PMH endpoints), one is deployed but crawler-blocked (the
    DSpace REST layer), one is behind institutional SSO with a live but undocumented edge (TISS), one is token-gated with
    a public contract (FUNDify), and two are pure identity metadata (the RIS Synergy OIDC realm and the SAML IdP). Exactly
    one OpenAPI exists and it is TU Wien''s own; no vendor contract is saved here. What is genuinely absent is central: no
    developer portal, no API key issuance, no status page, no changelog, no deprecation policy, no open-data portal (data.tuwien.ac.at
    does not resolve), and no llms.txt.'
