Live OAI-PMH 2.0 metadata harvesting endpoint for Deep Blue Documents, the University of Michigan Library's DSpace institutional repository of articles, dissertations, theses and archival collections. All six protocol verbs were probed live on 2026-08-19 and all returned HTTP 200: Identify, ListMetadataFormats (12 prefixes — oai_dc, qdc, mods, mets, marc, rdf, ore, didl, dim, xoai, etdms, uketd_dc), ListSets (726 sets), ListIdentifiers, ListRecords and GetRecord. Unauthenticated and open. Records go back to 2005-08-29. Protocol errors are returned with HTTP 200 inside the envelope — four error codes (badVerb, badArgument, cannotDisseminateFormat, idDoesNotExist) were reproduced against this host. The University of Michigan does not publish an OpenAPI description of this endpoint; the one in this repo was written by API Evangelist from those probes.
