OPARA OAI-PMH Harvesting Interface
The standards-based harvesting interface for OPARA — how TU Dresden's research data reaches OpenAIRE, BASE, re3data and the rest of the aggregator layer. Identify returns protocolVersion 2.0, earliestDatestamp 2018-04-05T11:49:14Z, deletedRecord transient and granularity to the second. ListMetadataFormats returns twelve prefixes — oai_dc, qdc, mods, didl, ore, mets, rdf, marc, xoai, dim, etdms and uketd_dc — which is a configured repository rather than a stock install. ListSets exposes named communities for four institutions: Technische Universität Dresden, Technische Universität Bergakademie Freiberg, Hochschule für Technik und Wirtschaft Dresden and Hochschule Mittweida, each split into Data Submissions and Research Data Archives. A ListRecords call with metadataPrefix=oai_dc returned 263,680 bytes of live Dublin Core. Protocol errors are returned inside a 200 envelope, as OAI-PMH requires — verb=Bogus yields Illegal verb. The repository is registered in re3data as r3d100012966.
