--- name: Tohoku University description: Tohoku University public developer/API footprint review for APIs.json cataloging. url: https://raw.githubusercontent.com/api-evangelist/tohoku/refs/heads/main/review.yml created: '2026-06-03' modified: '2026-09-01' reviews: - date: '2026-09-01' rating: 3 summary: >- University-pipeline re-profile with the operator axis applied before anything was saved. The 2026-06-03 pass recorded a single surface — the TOUR OAI-PMH endpoint — and concluded the university had no API. That conclusion was wrong in one important place and right everywhere else. jMorp, the Japanese Multi Omics Reference Panel published by the Tohoku Medical Megabank Organization on the university's own domain, exposes a public, unauthenticated GraphQL API with introspection enabled: 4,470 types, a 305-field read-only query root, a subscription root, no mutation root. It was exercised anonymously end to end and is the one surface on this profile that is genuinely Tohoku University's engineering. Two further institution-side relationships were found that a host-only reading misses: the university's own SAML 2.0 Shibboleth Identity Provider registered in GakuNin (entityID https://idp.auth.tohoku.ac.jp/idp/shibboleth, scope auth.tohoku.ac.jp), and three Crossref DOI-registering memberships held by university units. TOUR was re-labelled x-operator tenant — the collection and the admin contact are Tohoku's, the OAI-PMH implementation is NII's, and NII's contract is deliberately not saved here. Nothing was deleted to reach this shape. Absences confirmed and recorded rather than papered over: no developer portal, no OpenAPI, no llms.txt, no security.txt, no MCP server, no open-data portal (data./opendata./api.tohoku.ac.jp all NXDOMAIN), zero DataCite providers, no evidenced ORCID institutional membership. Japanese-language surfaces were searched as well as English, which is how the generative-AI guidance and the public QuickSyllabus course catalog were found. endpoints: - url: https://jmorp.megabank.tohoku.ac.jp/api/graphql status: 200 note: >- Anonymous POST.

The one clearly public, documented, machine-readable API is the TOUR institutional repository OAI-PMH 2.0 endpoint, which I verified live (Identify and ListMetadataFormats both returned valid OAI-PMH XML; formats include oai_dc, JPCOAR 1.0/2.0, DDI, LOM). The library OPAC is a public web search interface but no documented API was confirmed; the WEKO3 search endpoint returned HTTP 400 and is not cataloged as an API. Research code lives in lab GitHub orgs (e.g. cl-tohoku NLP group), not a central org. No endpoints were fabricated. endpoints: - url: https://tohoku.repo.nii.ac.jp/oai?verb=Identify status: 200 note: Valid OAI-PMH Identify, repositoryName "Tohoku University Repository（TOUR）", protocol 2.0. - url: https://tohoku.repo.nii.ac.jp/oai?verb=ListMetadataFormats status: 200 note: Returns oai_dc, jpcoar_1.0, jpcoar_2.0, ddi, lom metadata formats. - url: https://tohoku.repo.nii.ac.jp/ status: 200 note: TOUR repository human landing page (NII JAIRO Cloud / WEKO3). - url: https://www.tohoku.ac.jp/en/ status: 200 note: Official English homepage; no developer/API or open-data link surfaced. - url: https://www.library.tohoku.ac.jp/en/ status: 200 note: Library site; uses OPAC, no documented public API confirmed. - url: https://tohoku.repo.nii.ac.jp/search?search_type=2&q=test status: 400 note: WEKO3 search endpoint returned 400 Bad Request; not cataloged as an API. - url: https://github.com/cl-tohoku status: 200 note: Tohoku NLP research group GitHub org; not central institutional IT. - url: https://www.linkedin.com/school/tohoku-univ/ status: 200 note: Official LinkedIn school page.
