Brown Digital Repository IIIF Image and Presentation API
The BDR's IIIF surface, on the same institution-operated host. IIIF Image API 2.x (info.json reports a 6335x8560 source with a seven-step size pyramid and 512x512 tiles for the probed object) and IIIF Presentation API 2.x (sc:Manifest with a metadata block projected from the object's MODS record). Both are version 2.x; IIIF Presentation 3.0 has been the recommendation since 2020 and Brown has not migrated. The paths are not advertised anywhere and /iiif is disallowed in the repository's robots.txt — the documented route in is the item API's links.views.iiif_image_info and links.views.iiif_manifest keys. Brown is a IIIF community case study.
