OPARA OAI-PMH Harvesting Interface is one of 7 APIs that [TU Dresden](https://apis.io/providers/tu-dresden/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include OAI-PMH, Metadata, Harvesting, Open Access, and Research Data. The published artifact set on APIs.io includes API documentation.

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 <error code="badVerb">Illegal verb</error>. The repository is registered in re3data as r3d100012966.
