description: 'The University of Copenhagen (Københavns Universitet, UCPH), founded in 1479, is Denmark''s oldest and largest
  university and one of the leading research institutions in the Nordic region. It operates no central developer portal, no
  REST API program and no open-data portal — api.ku.dk and developer.ku.dk do not resolve, and data.ku.dk redirects to the
  homepage. What it does operate, and what makes it unusually well-covered for this cohort, is a set of standards-based machine-readable
  surfaces on its own infrastructure: a complete OAI-PMH 2.0 repository at curis.ku.dk serving 440,535 research records across
  7,430 sets in six metadata formats; a signed SAML 2.0 identity provider at id.ku.dk registered in the Danish WAYF federation;
  and thirteen Darwin Core Archive feeds published by the Natural History Museum of Denmark from specify-snm.science.ku.dk
  and harvested by GBIF. Its public research portal researchprofiles.ku.dk is by contrast an Elsevier Pure tenancy — it CNAMEs
  to ku.elsevierpure.com and its REST contract is Elsevier''s, api-key gated — and is recorded here as a tenant relationship
  rather than as the university''s own API. The only source code the institution publishes is the ku-kom GitHub account: 52
  repositories of TYPO3 content elements and a Bootstrap styleguide that build the ku.dk web platform.'

    anonymous request on 2026-08-30. The Elsevier Pure REST contract behind the same host is api-key gated (401), but that
    is the vendor's surface.

x-coverage:
  state: covered
  reason: covered
  detail: 'Re-profiled 2026-08-30 under the university pipeline. The June 2026 profile recorded one research-portal entry
    and asserted that the Pure endpoints "could not be confirmed reachable from the public internet" — that conclusion was
    reached by probing the wrong host. The Pure portal researchprofiles.ku.dk does not serve OAI-PMH (its /ws/oai returns
    500 and redirects to /error/), but curis.ku.dk does, and it answers all six OAI-PMH verbs at 200 unauthenticated. Two
    further institution-operated surfaces were found that had never been catalogued: the SAML 2.0 identity-provider metadata
    at id.ku.dk, and the Natural History Museum''s Darwin Core Archive feeds on specify-snm.science.ku.dk. One correction
    runs the other way: researchprofiles.ku.dk was previously carried as institution-operated on the strength of its ku.dk
    hostname, and DNS resolution shows it CNAMEs to ku.elsevierpure.com; it is re-labelled x-operator tenant. Negative results
    are real too — www.ku.dk answers 200 with a 121,943-byte homepage for every unknown path, so llms.txt, /.well-known/security.txt,
    /.well-known/ai.txt and /en/ai are all soft-404s and none is credited.'

    names the repository "University of Copenhagen", gives adminEmail curis@adm.ku.dk and attributes ownership to the org
    unit "KU Forskning og Informationssikkerhed". curis.ku.dk resolves to 130.226.237.49, inside the same University of Copenhagen
    /24 as cmsgw.adm.ku.dk and skema.ku.dk — this is the institution's own infrastructure, not the Elsevier tenancy. Six metadata
    formats (oai_dc, oai_cerif_openaire, mods, xmetadiss, fi-person, ddf-mxd), 7,430 sets, and 440,535 records in oai_dc over
    openaire_cris_publications. Declares OpenAIRE CERIF compatibility level 1.1.1. The software underneath is Pure 5.30.3-3,
    but the protocol is an open OpenArchives standard, so the contract described is Copenhagen's deployment of a public standard
    rather than a vendor's proprietary API.

  description: The Natural History Museum of Denmark, a University of Copenhagen faculty museum, publishes thirteen Darwin
    Core Archive exports from the Faculty of Science's own host specify-snm.science.ku.dk — entomology, mycology, ornithology,
    mammalogy, herpetology, ichthyology, invertebrate zoology, quaternary zoology, vertebrate palaeontology, vascular plants,
    biocultural botany, amber and the Danekræ collection. GBIF harvests them under publishing organization 2e7df380-8356-4533-bcb3-5459e23c794e
    (34 datasets in total; the remaining 21 arrive via ipt.danbif.dk and danbif.au.dk, which are not Copenhagen's infrastructure).
    These zips are the only bulk open-data downloads the university serves from a host it operates. The feed directory itself
    returns 403 to a listing request — normal for a directory of files, not a dead host; the individual archives under it
    return 200 application/zip.
