University of California, Santa Barbara

aid: ucsb
name: University of California, Santa Barbara
description: 'University of California, Santa Barbara is a public land-grant research university in the University of California
  system and an Association of American Universities member. Unusually for this cohort, UCSB runs a real, institution-operated
  API programme rather than a shelf of vendor contracts: a Campus API Gateway at api.ucsb.edu, a developer portal at developer.ucsb.edu
  cataloging 37 campus APIs across Academics, Administration, Dining, Employees, Housing and Students, a written and binding
  API design standard for campus publishers, and 21 downloadable first-party OpenAPI documents — every one of which declares
  a ucsb.edu host, so none of it is misattributed vendor engineering. The programme is real but it is closed: portal accounts
  are approved by hand, 25 of the 37 APIs sit above the Auto-Approved tier, and no endpoint is callable without an approved
  consumer key (an unauthenticated probe returns 401). UCSB also operates its own Shibboleth identity provider registered
  in InCommon, whose SAML metadata is openly machine-readable, and the Alexandria Digital Research Library, which is institution-run
  but has no API. Its library discovery layer and its open-access scholarship are vendor and UC-system tenancies and are recorded
  as such. There is no open-data portal, no OAuth authorization server, no llms.txt and no changelog.'

  x-audit-note: 'A cohort-derived host verdict reads escholarship.org as "vendor" because several UC campuses claim it. That
    is correct about the HOST and is exactly why no eScholarship contract is saved under this slug. The entry is retained
    at x-operator: tenant because the relationship itself is a real institutional fact — UCSB''s open-access collection lives
    there — and the pipeline is explicit that a tenant relationship must be re-labelled, never deleted, to avoid a misattribution.
    Nothing here is credited to UCSB: see the oai-pmh and datacite entries in conformance/ucsb-conformance.yml, both scored
    conforms:false with operator:tenant.'

  detail: 'UCSB is one of the genuinely programmable institutions in this cohort, but nothing it publishes is callable without
    a manually approved account. The CONTRACTS are open: 21 first-party OpenAPI documents download anonymously from developer.ucsb.edu
    and every one declares a ucsb.edu host, so the estate is fully readable and fully attributable. The ENDPOINTS are not:
    api.ucsb.edu returns 401 to any request without a ucsb-api-key, portal registration is approved by hand, 25 of 37 catalogued
    APIs sit above the Auto-Approved tier, and 16 of the 37 do not expose a contract publicly at all — their portal pages
    return an Access-denied body under HTTP 200. No response bodies, rate-limit headers or live schemas could therefore be
    captured. The gap is authorization, not absence.'

  detail: 'The cohort audit builds host verdicts from servers[] only. 19 of the 21 UCSB contracts are Swagger 2.0 and declare
    their host the Swagger 2.0 way — a top-level `host:` plus `basePath:` — so they list as HOSTLESS even though every one
    of them names a UCSB host explicitly. Judged by what each spec says about itself, per the ownership rule: 18 declare host:
    api.ucsb.edu and 1 (Grad Application Verifications) declares host: gradpoint.ucsb.edu. Both are under ucsb.edu. Zero name
    a vendor host, zero carry a vendor info.contact, zero carry a vendor info.title. All 19 are x-operator: institution and
    none is a candidate for removal. A derived servers[] block was tried on the working copies to make the host machine-visible,
    but it made all 19 read as MISBASED against their pristine _original parents (which have no servers[] at all), so it was
    reverted: HOSTLESS is the truthful state here and MISBASED would have been a false defect. The durable fix belongs in
    the audit, which should read Swagger 2.0 host+basePath when servers[] is absent.'
