The University of Göttingen (Georg-August-Universität Göttingen) is a public research university in Lower Saxony, Germany, founded 1737, a German U15 member and QS-ranked in the mid-200s. Its programmable footprint is real but small, and it belongs almost entirely to the Göttingen State and University Library (SUB Göttingen) rather than to the university's central IT: two live OAI-PMH 2.0 harvesting endpoints on the university's own domains — the Göttinger Digitalisierungszentrum, harvesting back to 1998, and the eDiss dissertation server, which disseminates the German national xMetaDissPlus, epicur and picaxml profiles — plus a IIIF Image API 2.0 level-2 image service and IIIF Presentation manifests for the digitised collections. The university also operates its own SAML 2.0 identity provider, registered in DFN-AAI, exported to eduGAIN and Sirtfi-compliant, and holds the DataCite prefix 10.25625 as repository client SUBGOE.GRO. There is no central developer portal, no self-service API key, no published rate limits and no OpenAPI authored by the institution; every specification in this repository was written by API Evangelist from live probes and is marked as such. The GRO.data research-data repository and the SUB library catalogue are recorded here as relationships rather than as Göttingen contracts — GRO.data runs Dataverse and the catalogue resolves onto the GBV/VZG library platform.
University of Göttingen publishes 3 APIs on the APIs.io network: GDZ OAI-PMH Metadata Harvesting, eDiss Göttingen OAI-PMH Metadata Harvesting, and SUB Göttingen IIIF Image and Presentation. Tagged areas include University, Higher Education, Education, Germany, and German U15.
University of Göttingen’s developer surface includes engineering blog, documentation, support, authentication, and 23 more developer resources.
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 does not apply to this provider. The published contracts declare
no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's
denominator entirely — not scored zero. A reference or data API is not deficient for being unable to
upsert.
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/.

be a vendor's by definition. Operated with GWDG; the login front end identifies itself as GWDG SSO / SimpleSAMLphp and

description: GRO.data is the Göttingen Campus research-data repository, operated by the Göttingen eResearch Alliance and
hosted at GWDG on data.goettingen-research-online.de. The deployment, the data and the DOIs are Göttingen's — DataCite
client SUBGOE.GRO holds prefix 10.25625 — but the REST and OAI contracts are Dataverse's, not the university's. Thirty-two
split OpenAPI documents describing Dataverse 6.4, re-titled "GRO.data Dataverse REST …" and attributed to the university,
were removed from this repository on 2026-08-30 for exactly that reason; the relationship is kept, the vendor's contract
is not. Both this host and publications.goettingen-research-online.de currently sit behind a proof-of-work bot challenge
that answers 403 to programmatic clients, so neither the REST API nor the OAI-PMH endpoint is reachable to a harvester.

x-coverage:
state: covered
reason: covered
detail: 'Four institution-operated surfaces were found, probed and specified — two OAI-PMH 2.0 repositories (GDZ, harvesting
back to 1998, and eDiss), a IIIF Image API 2.0 level-2 image service with Presentation manifests, and the university''s
own DFN-AAI/eduGAIN SAML identity provider. Three further surfaces exist but are not Göttingen contracts and are recorded
as relationships: GRO.data (Dataverse), the library catalogue (CNAME to GBV/VZG) and the self-hosted Stud.IP deployment.
There is no central developer portal, no self-service API key, no published rate limits and no institution-authored OpenAPI
anywhere in the estate; every specification here was written by API Evangelist from live probes and is marked method:
probed. Two limits on this pass are worth naming. First, the goettingen-research-online.de hosts (GRO.data and GRO.publications)
sit behind a proof-of-work bot challenge that answered 403 to every probe including with a browser User-Agent, so their
REST and OAI surfaces could not be read — live but unreadable, not dead. Second, the SUB Göttingen website has been reorganised
and its digital-library documentation paths now 30x to the library homepage while still answering 200; the two SUB documentation
pointers previously recorded here were dead in substance and graded live by status code, and both have been replaced.'
