DI-fusion OAI-PMH Harvesting Endpoint is one of 4 APIs that [Université libre de Bruxelles](https://apis.io/providers/ulb/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Research, Open Access, OAI-PMH, and Metadata Harvesting. The published artifact set on APIs.io includes an OpenAPI specification.

OAI-PMH 2.0 endpoint for the DI-fusion repository. Answers verb=Identify and verb=ListMetadataFormats with valid protocol documents (advertising oai_dc only), but under HTTP 500 and with an HTML page appended after the closing tag. Every record-bearing verb rejects the advertised metadataPrefix=oai_dc with badArgument "Missing Metadata Prefix", so no metadata can be harvested despite DI-fusion being registered as OAI-PMH compliant in OpenDOAR, ROAR and Sherpa. Recorded as measured, not as advertised.
