Yonsei University (연세대학교) is a private research university in Seoul, South Korea, founded in 1885 and one of the "SKY" institutions. Its programmable footprint is small, and most of what previously appeared under its name was not its own engineering: the Yonsei Research Information portal at yonsei.elsevierpure.com is an Elsevier Pure (CRIS) tenancy whose OpenAPI is authored by Elsevier — info.title "Pure API", contact pure-support@elsevier.com — and whose data endpoints and OAI-PMH feed both return HTTP 401 to the public. That relationship is recorded here as a tenant surface; the contract itself belongs to Elsevier and has been removed from this repo. What Yonsei genuinely operates is narrower and more interesting: a SAML 2.0 Identity Provider on its own domain (kafe.yonsei.ac.kr) registered in the Korean Access FEderation and exported to eduGAIN with the scope yonsei.ac.kr and a Sirtfi declaration; a DSpace 5.5 medical-library repository (YUHSpace) at ir.ymlib.yonsei.ac.kr serving public RSS 2.0 and Atom 1.0 feeds from behind a JavaScript bot challenge, with no OAI-PMH deployed; and a members-only Yonsei Data Portal at data.yonsei.ac.kr that ships no public API. There is no central developer portal, no institution-operated REST API, and no official institutional GitHub organization — the only GitHub presence is GDGoC Yonsei, a student Google Developer Group. The institutional AI posture is a governance document, not an API, and it exists only on the Korean surface.
Yonsei University publishes 4 APIs on the APIs.io network. Tagged areas include University, Higher Education, Education, Private Research University, and South Korea.
Regulatory Posture applies to this provider. Its tags matched the
Education & Research regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/yonsei: open an issue to ask a question, or submit a pull request to add artifacts.

detail: 'Yonsei publishes no institution-operated REST API and no developer portal. The only complete API contract discoverable
under its name is Elsevier''s Pure API, served from the tenant host yonsei.elsevierpure.com: the specification at /ws/api/openapi.json
is publicly readable (HTTP 200, ~1.7MB) but every data endpoint returns 401 and the Pure OAI-PMH feed at /ws/oai returns
401 as well. The 37 per-tag OpenAPIs previously stored in this repo were splits of that one Elsevier document and have
been removed. The institution''s own machine-readable surfaces are a SAML 2.0 IdP registered in KAFE and eduGAIN, and
DSpace RSS/Atom feeds reachable only after satisfying a JS bot challenge. The medical-library repository has no OAI-PMH
webapp deployed (404 on /oai/request, /dspace-oai/request and /oai/driver). Yonsei''s generative-AI guideline exists only
in Korean, on yure.yonsei.ac.kr, and was found by searching in the local language.'

IDPSSODescriptor role, the shibmd:Scope yonsei.ac.kr, and a REFEDS Sirtfi declaration, first seen 2024-02-23. The software
is SimpleSAMLphp. This is the university''s strongest institution-operated machine-readable surface: identity federation
is institution-operated by definition, and Yonsei''s own server says so in Korean — "본 서버는 KAFE 연합인증 서비스의 제공을 목적으로 연세대학교에서
운영합니다." Metadata is not exposed at a public URL on the host; it is distributed through the KAFE aggregate and eduGAIN,
which is standard federation practice.'

description: 'Yonsei''s research information system is an Elsevier Pure (CRIS) tenancy at yonsei.elsevierpure.com. The data
is Yonsei''s — its researchers, outputs, projects and organizational units — but the contract is not: the OpenAPI served
at /ws/api/openapi.json declares info.title "Pure API", version 5.35.3-4, and contact pure-support@elsevier.com, and the
same document is shipped by at least nine other institutions in this catalog. It is Elsevier''s engineering running under
Yonsei''s name. The specification is publicly readable, but the API itself is closed: /ws/api/research-outputs returns
401 with "Full authentication is required to access this resource", and the Pure OAI-PMH feed at /ws/oai returns 401.
Thirty-seven per-tag OpenAPIs split from this one Elsevier document, and every schema, example, collection, ruleset, vocabulary,
JSON-LD context, authentication record and agentic-access record derived from it, were removed from this repo on 2026-08-30;
they score against Elsevier, not against Yonsei. The tenant relationship is kept because it is a real institutional fact
and one of the few programmable surfaces the university has.'
