University of Göttingen

SUB Göttingen IIIF Image and Presentation

IIIF Image API 2.0 (level 2) image service at images.sub.uni-goettingen.de and IIIF Presentation manifests routed through gdz.sub.uni-goettingen.de with canonical identifiers on manifests.sub.uni-goettingen.de. All three hosts resolve into the university's own address space. Verified live on 2026-08-30 against identifier gdz:PPN519929969:00000001 — info.json, a JPEG derivative and a full Presentation manifest all returned 200. The IIIF specifications belong to the IIIF community; the deployment, the identifier scheme and the level-2 profile are Göttingen's.

  title: SUB Göttingen IIIF Image and Presentation Interfaces
  description: >-
    IIIF Image API 2.0 (level 2) and IIIF Presentation API deployment operated by the Göttingen
    State and University Library (SUB Göttingen) for the Göttinger Digitalisierungszentrum (GDZ)
    and the university's digitised collections. Images are served from
    images.sub.uni-goettingen.de and manifests from manifests.sub.uni-goettingen.de, both on the
    university's own `sub.uni-goettingen.de` domain and both resolving into the university's
    address space.

    IIIF is a community specification, not a Göttingen one. What is Göttingen's is this
    deployment: the identifier scheme (`gdz:PPN<record>:<page>`), the manifest routing under
    gdz.sub.uni-goettingen.de/iiif/presentation/, and the level-2 image service profile actually
    advertised by the live info.json.

    Every path below was confirmed against the live services on 2026-08-30.
