    summary: >-
      Re-profiled under the API Evangelist university pipeline, which settles WHO OPERATES a
      surface before crediting it to the institution. The 2026-06-03 review above is superseded
      in one respect and corrected in two others, and is kept for the record. SUPERSEDED: the
      "EUR research data repository hosted on Figshare, accessible via the public Figshare v2
      REST API" was not an EUR API. api.figshare.com/v2 is the generic host every Figshare
      customer shares — twenty-five universities in this cohort claimed it — and the ten OpenAPI
      contracts saved here from it, plus 41 artifacts derived from them, have been removed (51
      files). The relationship itself has also ended: Erasmus University Library moved the EUR
      Data Repository to DataverseNL, hosted by DANS, on 30 October 2025, and datarepository.eur.nl
      now returns NXDOMAIN rather than merely failing to resolve from one probe host. CORRECTED:
      https://pure.eur.nl/ws/oai?verb=Identify no longer returns 500 — it answers 200 with the
      OpenAIRE CERIF-XML 1.2 profile and can be harvested. CORRECTED: the June review found no
      course/timetable/SIS or identity APIs; both exist as tenancies (Caci OSIRIS at
      eur.osiris-student.nl, and a SURFconext/eduGAIN identity-provider registration), and EUR
      also runs a Kong API gateway of its own at api.eur.nl that the June pass did not probe.
      The rating is unchanged at 2: removing someone else's contracts lowers the artifact count
      but the underlying footprint — one keyless institution-operated OAI-PMH endpoint, one
      closed gateway, five tenancies, no published contract of any kind — is what it always was.

    summary: >-
      Erasmus University Rotterdam has no consolidated public developer portal. Its
      programmatic surface is research/scholarly infrastructure. The RePub OAI-PMH
      feed was verified live, returning valid OAI-PMH 2.0 XML self-identifying as
      "Erasmus University OAIPMH Feed". The Pure research portal resolves but its
      OAI service path returned HTTP 500 on the Identify verb, so it is listed but
      flagged for re-verification. The EUR research data repository is hosted on
      Figshare and accessible via the public Figshare v2 REST API. The official
      eur-nl GitHub org exists (18 repos). No course/timetable/SIS, identity, or
      mobile-backend APIs were found publicly documented. No endpoints were
      fabricated; only confirmed URLs are listed.
