summary: >-
  The University of Leeds publishes no versioning policy, no deprecation policy, no changelog and no
  status page for any of its machine-readable surfaces. Two of the four are protocol-versioned by
  the standard they implement rather than by the institution; the other two are unversioned static
  files that can change shape without notice.
surfaces:
  - surface: Research Data Leeds Repository OAI-PMH
    versioning: 'Protocol-versioned. OAI-PMH 2.0, declared as <protocolVersion>2.0</protocolVersion>.'
    stability: >-
      High by construction — the verb set and error vocabulary are fixed by the OAI-PMH
      specification, so a harvester written today will keep working. Repository content changes;
      the interface does not.
    deletion_policy: 'deletedRecord = persistent (declared in Identify) — deleted records remain harvestable as tombstones.'

  - surface: Leeds Digital Library OAI-PMH / OpenSearch
    versioning: 'Protocol-versioned. OAI-PMH 2.0 and OpenSearch 1.1.'
    earliest_datestamp: '2012-09-04T17:15:58Z'
    stability: >-
      Same protocol guarantee. Note the Identify response still declares an http:// baseURL while the
      host serves https — a small inconsistency in the repository's self-description.
    evidence: { url: 'https://digital.library.leeds.ac.uk/cgi/oai2?verb=Identify', status: 200 }
  - surface: Spacefinder space data
    versioning: 'NONE. Unversioned static JSON at a fixed path; no version field in the payload, no dated snapshot, no changelog.'
    stability: >-
      Reversibility risk. The shape can change at any commit to
      github.com/uol-library/spacefinder.leeds.ac.uk with no notice to consumers. The public git
      history is the only change record, and it is the application's history, not a data changelog.
      One shape hazard is already present: `location` is a GeoJSON Point serialised as a string.
    evidence: { url: 'https://spacefinder.leeds.ac.uk/spaces.json', status: 200 }
  - surface: Library floor plans IIIF Image API
    versioning: 'Protocol-versioned. IIIF Image API, compliance level 0.'
    stability: >-
      Identifiers (brotherton-m1 and siblings) are stable and enumerated in the service data, but
      only pre-generated derivatives resolve, so a consumer must read info.json rather than
      constructing requests.
    evidence: { url: 'https://floorplans.library.leeds.ac.uk/assets/iiif/original/brotherton-m1/info.json', status: 200 }
absent:
  status_page: 'None found on any leeds.ac.uk host.'
  changelog: 'None. GitHub commit history for the two Libraries applications is the nearest equivalent.'
  deprecation_policy: 'None published.'
  sunset_headers: 'Not present on any probed response.'
