description: University of Melbourne does not publish a unified public rate-limit table across its APIs.
  Open metadata and harvesting endpoints (OAI-PMH, IIIF, library) may throttle large-scale or automated
  harvesting; clients should harvest politely, honor Retry-After, and contact the relevant service for
  bulk access.
notes: 'Confirmed by probe 2026-08-19: NO rate-limit signal of any kind is returned by the institution-operated
  surfaces. GET https://sudo.eresearch.unimelb.edu.au/api/v2/ returned Allow: GET, HEAD, OPTIONS with
  no RateLimit-* or Retry-After header, and neither the Minerva Access DSpace REST API nor the OAI-PMH
  endpoint publishes a quota. Absence of a header is not a guarantee of no limit - harvest politely. The
  IIIF and library interfaces referenced in the description above were NOT verified in the 2026-08-19
  pass and should be treated as unconfirmed.'
