**Canonical:** https://apis.io/apis/ucd/oai-pmh/

Research Repository UCD — OAI-PMH 2.0 is one of 6 APIs that [University College Dublin](https://apis.io/providers/ucd/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include OAI-PMH, Repository, Open Access, Metadata, and Research. The published artifact set on APIs.io includes an OpenAPI specification and API documentation.

Keyless, anonymous OAI-PMH 2.0 metadata harvesting for UCD's open-access institutional repository. Verified live 2026-08-30: all six verbs return HTTP 200 with a well-formed envelope, ListIdentifiers reports completeListSize 17167, earliestDatestamp is 2007-08-22, granularity is YYYY-MM-DDThh:mm:ssZ, and fourteen metadata formats are advertised (oai_dc, qdc, dim, didl, mets, mods, ore, rdf, marc, marc21, etdms, uketd_dc, rian_dc, rms_oai — rian_dc for the Irish national aggregator RIAN, uketd_dc and etdms for theses). A second base URL, /server/oai/openairecris, serves the OpenAIRE Guidelines for CRIS Managers 1.1 CERIF profile. Protocol errors behave correctly: badVerb, cannotDisseminateFormat and idDoesNotExist are returned inside HTTP 200 envelopes. Records carry Handle identifiers under UCD's prefix 10197 and, in the dim format, qualified ORCID fields. NOTE the base URL: the /oai/request path recorded in this file in June 2026 returns 405; the working path is /server/oai/request. The OpenAPI below is DERIVED by API Evangelist from live probes — UCD publishes none.
