description: Peking University (北京大学, PKU) is a public research university in Beijing and, with Tsinghua, one of the two apex
  institutions of the Chinese system. Like most universities it operates no central developer portal and publishes no OpenAPI,
  but unlike most it runs three genuinely institution-operated machine-readable surfaces. Its Institutional Repository at
  ir.pku.edu.cn — PKU Library, Handle prefix 20.500.11897, content back to 2015 — answers an unauthenticated JSON REST API,
  a conforming OAI-PMH 2.0 endpoint advertising twelve metadata formats, and an OpenSearch Atom feed. Its Shibboleth identity
  provider publishes live SAML 2.0 metadata and has been in eduGAIN production since June 2019. Most significantly, the Peking
  University Computer Center operates CARSI, China's national research-and-education identity federation and a full eduGAIN
  member, which is the registration authority for 1,042 federated entities and serves 500+ Chinese universities; PKU also
  runs the national eduroam service. The PKU HPC group additionally authors OpenSCOW and CraneSched, open-source HPC platform
  and scheduler whose APIs are defined in some forty Protocol Buffer files, though those describe self-hosted software rather
  than a hosted endpoint. The Dataverse-based Open Research Data Platform at opendata.pku.edu.cn was verified live in June
  2026 but did not answer any HTTPS request during this pass. No API is documented for developers, none carries a versioning
  or deprecation policy, and campus systems — IAAA authentication, the 教学网 LMS, the registrar — are gated. The footprint is
  small, real, and almost entirely a by-product of scholarly infrastructure rather than a developer programme.

x-coverage:
  state: covered
  reason: institution_operated_surfaces_verified
  detail: 'Three institution-operated machine-readable surfaces were probed live and are documented here: the Institutional
    Repository REST API, its OAI-PMH 2.0 endpoint, and the university''s Shibboleth SAML 2.0 identity provider — plus CARSI,
    the national identity federation PKU itself operates, corroborated by eduGAIN''s registry. No vendor contract is attributed
    to the institution. One previously verified surface, the Dataverse-based Open Research Data Platform at opendata.pku.edu.cn,
    was unreachable over HTTPS across seven attempts with browser user-agents, forced HTTP/1.1 and forced IPv4; TLS completed
    against PKU''s own wildcard certificate and port 80 answered with a 301, and every other pku.edu.cn host answered normally
    in the same window, so the host is treated as unreadable from our vantage point rather than absent. Campus systems (IAAA,
    the LMS, the registrar) are authentication-gated by design and are recorded as such, not as gaps.'

    for the SCOW AI service. This is a real institution-authored API contract, but it describes software each site deploys
    itself — the generated document's only server is http://localhost:5006/api — so no hosted base URL is claimed.
