name: Stanford University — API vocabulary
description: >-
  The domain vocabulary Stanford's own surfaces speak, extracted from live payloads and from
  the five first-party Stanford Digital Repository contracts. This is deliberately Stanford's
  vocabulary, not a library-sector vocabulary: `druid` and `cocina` are Stanford-coined terms
  that other institutions do not use, and they are the clearest evidence that the SDR contracts
  are institution-engineered rather than a vendor platform wearing a Stanford name.

    definition: >-
      Digital Repository Unique Identifier — Stanford's own opaque object identifier, an
      eleven-character string of the form bb157hs6068. The primary key of every SDR object and
      the path segment of every PURL.

  - term: cocina
    definition: >-
      Stanford Libraries' metadata model for repository objects, versioned independently of the
      APIs that carry it. Emitted as `publishVersion="cocina-models/0.127.0"` on every published
      object and validated on write by the DOR Services API (422 on model violation).
    surfaces: [PURL, DOR Services API, SDR API]
    method: probed
  - term: PURL
    definition: >-
      Persistent URL. https://purl.stanford.edu/{druid} with .xml, .mods and /iiif/manifest
      projections of the same object.
    surfaces: [PURL]
    method: probed
  - term: SURI
    definition: >-
      Stanford Uniform Resource Identifier service — the institution's identifier minting API.
      Contract declares `identifiers` and `legacy` tags.
    surfaces: [SURI API]
    method: derived
  - term: SDR
    definition: Stanford Digital Repository — the preservation and access platform the five contracts serve.
    method: searched
  - term: administrative tag
    definition: >-
      A free-text classification applied to repository objects and searchable for autocomplete
      in Argo, Stanford's repository administration UI.
    surfaces: [DOR Services API]
    method: derived
  - term: user version
    definition: >-
      A citable, human-meaningful version of a repository object, distinct from the internal
      object version. Exposed as a `user_versions` parameter on version close.
    surfaces: [SDR API, DOR Services API]
    method: derived
  - term: moab
    definition: Stanford's on-disk preservation object layout, tracked by the Preservation Catalog.
    surfaces: [Preservation Catalog]
    method: derived
  - term: SUNet ID
    definition: >-
      Stanford University Network ID — the campus identity a person carries. Appears as the
      `user_name` audit parameter on DOR write operations and as the subject of Registry
      Person/Account services.
    surfaces: [DOR Services API, MaIS Registry]
    method: derived
  - term: Registry
    definition: >-
      Stanford's consolidated system of record for people, accounts, students, courses,
      privileges and workgroups, exposed as six MaIS web services.
    surfaces: [MaIS Registry APIs]
    method: searched
    evidence: 'https://uit.stanford.edu/service/registry — status 200'
  - term: workgroup
    definition: Stanford's campus-wide group construct, and the unit of access control for the AI Playground.
    surfaces: [MaIS Registry APIs, AI Playground]
    method: searched
  - term: PTA
    definition: >-
      Project-Task-Award — Stanford's internal billing string. Required to obtain an AI API
      Gateway key, which makes the gateway the one Stanford API with a real chargeback model.
    surfaces: [AI API Gateway]
    method: searched
  - term: High Risk data
    definition: >-
      Stanford's data risk classification tier. Determines which AI services may process which
      data; the AI API Gateway is approved for High Risk and PHI, the AI Playground for High
      Risk non-PHI only.
    method: searched

  - term: ExploreCourses view
    definition: >-
      A dated response-format selector on the Registrar's course query — `view=xml-20140630`.
      Functions as the API version.
