Those who are not familiar with IIIF would appreciate the acronym to be spelled out.

Dear Julie,

Thank you for your message.

IIIF stands for International Image Interoperability Framework. As it is not the first time that I post about IIIF on this forum, I didn't feel the need to do it, but you are right any acronyms should be spelled out. I will be more careful.

All the best,

John Kunze

Since Julien's original message was from almost 2 years ago, I'm reposting it below. It references the congruence between ARKs and IIIF identifiers.

Basically, the IIIF Image API delivers the pixels of an image in a simple and intuitive way that easily specifies the region, size, rotation, quality characteristics and format of the requested image.
  • The URI syntax is: {scheme}://{server}{/prefix}/{identifier}/{region}/{size}/{rotation}/{quality}.{format}
  • and the Information URI Syntax (in JSON) is {scheme}://{server}{/prefix}/{identifier}/info.json
In addition to the Image API, IIIF has also developed the Presentation API which provides just enough data about digital assets and their structure to drive a viewer experience. In IIIF jargon, we talk about canvases for images and manifests for digital objects (which are in a way the glue that structures all canvases together). The latter is also serialised in JSON.

  • IIIF recommends this URI pattern: {scheme}://{host}/{prefix}/{identifier}/manifest

ARK and IIIF URIs can easily be used together because IIIF is simply an extension giving more precise information about the region of interest of a given image (or soon of an audiovisual resource with API versions 3.0).

Gallica had also achieved in part what IIIF wanted to establish by using ARK qualifiers. For instance, this folio 42:

Thanks for the kind response.  I always thinks of how to find more members and this is one way; by always identifying the organization🙂

Kind regards,
