  x-derived-from: Hand-written from the Kyushu University Library's own published parameter documentation at lib.kyushu-u.ac.jp/ja/metadata, then corrected against live responses from the endpoint itself on 2026-09-01 (Identify, ListMetadataFormats, ListSets, ListIdentifiers, GetRecord, ListRecords and a deliberate badVerb). Kyushu University does not publish an OpenAPI description for this interface; this document is API Evangelist's, not theirs, and is marked derived so it is never credited to the institution as something they published.
  description: OAI-PMH 2.0 metadata harvesting interface for the digital collections of Kyushu University Library, including the Kyushu University Institutional Repository (QIR).

      summary: Issue an OAI-PMH 2.0 request
      description: Single OAI-PMH entry point. The `verb` parameter selects the operation; the remaining parameters are valid only for particular verbs, exactly as OAI-PMH 2.0 specifies. A request carrying `resumptionToken` MUST carry no other parameter except `verb`. The library caps a single ListRecords / ListIdentifiers response at 500 records and returns a resumptionToken for the remainder.

      parameters:
      - name: verb

        required: false
        description: Metadata format to return. Required for GetRecord, ListRecords and ListIdentifiers. The library documents `jpcoar` as the supported value and states that formats other than the JPCOAR schema are still being adjusted and are not guaranteed to be well-formed for their structure; ListMetadataFormats nevertheless advertises four.
