Keio University

aid: keio
name: Keio University
description: 'Keio University (慶應義塾大学) is a private research university in Tokyo, Japan, founded by Fukuzawa Yukichi in 1858
  and the oldest institution of modern higher education in the country. Its programmable footprint is small, entirely non-commercial,
  and — unusually for this cohort — genuinely its own rather than a vendor''s running under its name. Two surfaces are operated
  by Keio on Keio''s hosts and are anonymously consumable today: KOARA, the institutional repository, which serves a live
  OAI-PMH 2.0 harvesting interface advertising Dublin Core and the NII junii2 schema across 100 faculty and research-centre
  sets; and the Media Center''s Digital Collections, which serve IIIF Presentation 2.1 manifests and IIIF Image 2.0 Level
  1 tiles for the university''s digitised rare books, including all 656 folios of its Gutenberg 42-line Bible. Keio also operates
  its own Shibboleth/SAML identity provider, registered in the GakuNin federation since 2014 and republished into eduGAIN
  — the strongest institution-owned machine-readable artifact it has. Beyond those, the estate is a set of tenancies and registry
  memberships rather than engineering: K-RIS runs on Elsevier Pure, campus sign-on runs through an Okta tenant and an Extic-hosted
  SSO service, research data DOIs are minted through a Figshare consortium seat at DataCite, and two Keio units hold Crossref
  memberships in their own right. There is no developer portal, no API key, no changelog and no published OpenAPI anywhere
  in the estate; every contract in this repository was written by API Evangelist from live probes and is marked as such.'

    Keio has, and it was entirely absent from this catalog before 2026-09-01. Its one real limitation is discovery: collection

    — since 2014-02-24, and republished into eduGAIN as entity 853677. The metadata asserts scope keio.ac.jp, bilingual display
    names, discovery hints covering the 131.113.0.0/16 and 133.27.0.0/16 networks and the keio.ac.jp and keio.jp domains,
    and a technical contact at Keio's Information Technology Center. Identity federation is the surface class a university
    operates by definition and is almost never catalogued for; for Keio it is the strongest artifact carrying the institution's
    own name. The entityID and the scope are Keio's; the SSO endpoints resolve to keio.ex-tic.com, a Keio tenant on the Extic
    identity platform, which is recorded as a tenancy rather than deducted from the institution's ownership of the entity.

x-coverage:
  state: covered
  reason: covered
  detail: 'Keio is a correctly thin but genuinely non-empty profile, and the 2026-09-01 pass moved it from one surface to
    nine. Two institution-operated APIs are live, anonymous and fully consumable today — KOARA''s OAI-PMH 2.0 interface (all
    six verbs probed, 100 sets, oai_dc and junii2) and the Media Center''s IIIF Presentation 2.1 and Image 2.0 Level 1 endpoints
    (manifest, info.json and a rendered image request all 200). Keio also operates its own Shibboleth/SAML identity provider,
    registered in GakuNin since 2014 and republished into eduGAIN, which is the institution-owned surface class this cohort
    was most completely missing. Beyond those, the estate is tenancies and registry memberships, each recorded as a relationship
    with the vendor''s contract deliberately withheld: Elsevier Pure behind K-RIS (whose /ws/api returns 404, so not even
    the vendor''s interface is readable), an Okta tenant whose OIDC discovery is public but whose client registration is not
    reachable, a Figshare repository evidenced through DataCite''s registry rather than through the bot-interstitialled host,
    and DataCite, Crossref and ROR registrations. What Keio does not have is equally clear and was probed rather than assumed:
    api.keio.ac.jp and data.keio.ac.jp do not resolve, there is no developer portal, no open-data portal, no public course
    catalog or timetable API, no research-computing service catalog, no published OpenAPI or apis.json, no changelog, no status
    page, no llms.txt, no MCP server, and the main web estate serves neither robots.txt nor security.txt. No probe was blocked
    in a way that hid a finding; the only bot rejections encountered were LinkedIn''s 999 and Figshare''s 202, both platform
    edges rather than facts about Keio.'
