Spiral OAI-PMH Metadata Harvesting Endpoint
A fully functional OAI-PMH 2.0 harvesting interface — the standards-based way Imperial's research outputs reach OpenAIRE, CORE, BASE and the rest of the aggregator layer. Identify, ListMetadataFormats and ListSets all answer 200. Eleven metadata prefixes are served — oai_dc, qdc, mods, mets, marc, dim, rdf, ore, didl, etdms and uketd_dc — of which etdms and uketd_dc are the ETD and UK thesis profiles, evidence of a configured repository rather than a default install. A second base URL at /server/oai/openairecris declares OpenAIRE CERIF profile 1.1 compatibility. earliestDatestamp is 1916-01-01. No OpenAPI is saved for this surface: the protocol is OAI's, the implementation is DSpace's and the hosting is 4Science's, so authoring a contract here would credit Imperial with engineering it did not do.
