National Cheng Kung University
National Cheng Kung University (NCKU, 國立成功大學) is a public research university in Tainan, Taiwan, founded in 1931 and the second-largest comprehensive university in the country. Its programmable footprint is narrow and almost entirely accounted for by one surface: the NCKU Open Data Platform at data.ncku.edu.tw, a CKAN 2.0 deployment NCKU runs on its own host and its own domain, carrying 108 datasets and two NCKU-authored CKAN extensions (nckumetadata, nckutemplatehelper), released under Taiwan's Open Government Data License v1. Its Action API answers anonymous callers with valid JSON and is the only endpoint in this profile that returns machine-readable institutional data without credentials. Everything else is either a vendor tenancy or barely reachable. Library discovery is Ex Libris Primo VE under an NCKU tenant view (886NCKU_INST) and is recorded as a relationship, not as NCKU's engineering — no Ex Libris contract is saved here. The NCKU institutional repository (NCKUR) at nckur.lib.ncku.edu.tw is NCKU's own DSpace, confirmed live and self-identifying as "Powered By DSPACE, MIT" Version 7.0 during one of only three responsive windows in roughly thirty probes on 2026-09-01 — the host refuses TCP the rest of the time. No OAI-PMH or REST interface survived probing: /oai/request?verb=Identify returns a genuine 404 and every other candidate path fell inside a refusal window, so the 2026-06 profile's DSpace REST and OAI-PMH claims stay unverified. NCKU's Shibboleth identity provider resolves in DNS at idp.ncku.edu.tw but its ports do not answer from outside Taiwan, and Taiwan has no federation in eduGAIN, so the IdP is named as an unverified lead rather than credited as a surface. NCKU registers no DOI prefix with either DataCite or Crossref. There is no central developer portal, no API key program and no institution-authored OpenAPI anywhere on the ncku.edu.tw estate.

x-coverage:
state: covered
reason: covered
detail: 'NCKU was reachable and one genuine institution-operated machine-readable surface was verified: the CKAN Action
API at data.ncku.edu.tw answers status_show, site_read, package_list and package_show anonymously with valid JSON, reporting
ckan_version 2.0, site_title "National Cheng Kung University Open Data Platform" and two NCKU-specific extensions, over
108 datasets. That deployment is NCKU''s — their host, their data, their extensions — but the contract behind it is CKAN''s
product API, shared by every CKAN site in the world, so no OpenAPI is saved under NCKU''s name and the CKAN project''s
own documentation is linked instead. The 2026-06 profile''s three other claims did not survive probing. Library discovery
is not on www.lib.ncku.edu.tw at all: the library site links out to ncku.primo.exlibrisgroup.com with view 886NCKU_INST,
which is an Ex Libris Primo VE tenancy and is re-labelled x-operator tenant here. The institutional repository is real
and is NCKU''s, but its host is barely reachable: it refused TCP on 443 and 80 on most of roughly thirty attempts and
a direct nc port check timed out, while returning a full 200 three times — enough to confirm DSpace, nginx/1.18.0 and
handle prefix 987654321, and enough to establish that /oai/request?verb=Identify is a genuine application 404. The 2026-06
claim of a DSpace 7 REST API and OAI-PMH interface is left unverified rather than restated. One early fetch returned a
"Website Moved" interstitial pointing at mytheses.my; it is recorded as an anomaly on the enhancing vendor''s stack, not
as a migration. Searches were run in Traditional Chinese as well as English, which is how the generative-AI academic integrity
guideline and the NCKU AI learning resource site were found — both institution-published governance surfaces, neither
an API. Negative registry findings are recorded deliberately: api.datacite.org returns zero clients for "cheng kung" and
"ncku", api.crossref.org returns zero members, and eduGAIN lists no Taiwanese federation, so the only registry membership
evidenced is ROR 01b8kcc49.'

x-operator-evidence: data.ncku.edu.tw is under NCKU's own registrable domain (ncku.edu.tw) and resolves to 140.116.249.41,
inside NCKU's own 140.116.0.0/16 allocation. status_show reports site_url https://data.ncku.edu.tw, an ncku.edu.tw contact
address, and two extensions named for the institution — nckumetadata and nckutemplatehelper. The cohort audit flags that
the name CNAMEs to data.ncku.com.tw; that target resolves to the same 140.116.249.41, so ncku.com.tw is a second NCKU-controlled
name in front of the same NCKU-hosted server, not a vendor platform — it is merely delegated to Cloudflare nameservers
while ncku.edu.tw runs on NCKU's own apple/name.ncku.edu.tw, which is the only reason the two look unrelated. NCKU operates
the server and authored the customisation; the Action API contract itself is CKAN's product API, which is why no OpenAPI
is saved under NCKU's name.
description: 'NCKU''s institutional open data portal, a CKAN 2.0 deployment on NCKU''s own host publishing 108 datasets
from the university and its affiliated units — student enrolment and geographic distribution statistics, international
student counts, and the Smart University City (智慧大學城) education and energy datasets. The standard CKAN Action API is open
and anonymous: /api/3/action/package_list returns the full dataset id list, /api/3/action/package_show returns full dataset
metadata with resources, and /api/3/action/status_show confirms ckan_version 2.0 with the datastore, stats, recline_preview,
json_preview, pdf_preview and resource_proxy extensions enabled alongside NCKU''s own two. Data is released under Taiwan''s
Open Government Data License v1 (政府資料開放授權條款第1版), which the portal states is compatible with CC BY 4.0. robots.txt disallows
/api/ to crawlers, which is a courtesy directive rather than an access control — the endpoints answer normally.'

link on it points at ncku.primo.exlibrisgroup.com with view 886NCKU_INST — an institution-specific view on Ex Libris's
shared multi-tenant Primo VE platform. The 2026-06 profile recorded this surface against the institution's own library
host, which is what the host-based verdict saw; the service itself is Ex Libris's. Corrected to tenant.
description: NCKU Library's catalog and discovery layer runs on Ex Libris Primo VE backed by Alma, under the NCKU tenant
view 886NCKU_INST. The search interface is a Primo Angular application (primoExploreRoot) served from ncku.primo.exlibrisgroup.com
and returns 200 to an anonymous request. The collection, the holdings and the course reserves are NCKU's; the contract,
the platform and the API surface are Ex Libris's, and no Ex Libris specification is saved under NCKU's name. No NCKU-specific
Primo/Alma developer documentation, API key program or published REST base URL was found. NCKU also runs a RapidILL interlibrary
loan service at rapidill.lib.ncku.edu.tw, a second Ex Libris tenancy.

read as institution-operated.

x-operator: institution
x-operator-evidence: nckur.lib.ncku.edu.tw is under NCKU's own registrable domain and resolves to 140.116.207.17, inside
NCKU's own 140.116.0.0/16 allocation, adjacent to the library web server at 140.116.207.18. The served page identifies
itself as 國立成功大學機構典藏 (NCKU Institutional Repository) and its internal origin is 140.116.207.99, also NCKU's. The repository
is NCKU's; the software is DSpace, which is why no product contract is saved under NCKU's name.
description: 'NCKUR is NCKU''s institutional repository — theses, dissertations and university scholarly output under handle
prefix 987654321, with roughly 294 handle links on the front page alone. It self-identifies as "Powered By DSPACE, MIT",
Version 7.0, served by nginx/1.18.0 on Ubuntu, with a locally enhanced JSPUI-style interface (/feed/rss_1.0/, /feed/rss_2.0/,
/feedback?fromPage=). The host is severely unstable from outside Taiwan: across roughly thirty probes on 2026-09-01 it
refused TCP on 443 and 80 the large majority of the time and a direct nc port check timed out, but it did return a full
200 (92,896 bytes) three times, and one of those windows was long enough to confirm the software. No harvesting or REST
interface could be confirmed: /oai/request?verb=Identify returns a genuine application 404, and /server/oai/request, /dspace-oai/request,
/server/api and /rest were never reachable within a responsive window. The 2026-06 profile''s assertion of a DSpace 7
REST API and OAI-PMH interface is therefore still unverified and is not claimed here. One anomaly is on the record: a
single early fetch returned a 1,616-byte "Our Website Has Moved" interstitial counting down to mytheses.my, an off-institution
destination, which is most likely the enhancing vendor''s default virtual host leaking through rather than a migration
of NCKU''s repository.'
