Commons:International Image Interoperability Framework

What is IIIF?

The International Image Interoperability Framework (IIIF, pronounced as 'triple-eye-ef') is a standard for sharing images (and other media files) across the web, which makes image and media repositories interoperable with each other. IIIF is widely supported by cultural institutions around the world.

To get an idea – with examples – of what types of applications become possible with IIIF, see this blog post (June 2018) from the Wellcome Collection.

IIIF and Wikimedia projects

As of 2018, default IIIF integration is not on the official development roadmap for Wikipedia, Wikimedia Commons or other Wikimedia projects (such as Wikidata). The IIIF community and the Wikimedia community, however, are in touch with each other, exploring options together.

• Several volunteer-developed tools offer IIIF functionality for media files on Wikimedia Commons. See below for a list of tools. Please add examples if you know them.
• Since November 2018, there is a Wikidata property IIIF manifest URL (P6108) that links Wikidata items of artworks to their IIIF manifests hosted by cultural institutions.
  • Wikidata SPARQL query that lists all Wikidata items with this property (click the blue arrow button at the bottom left to run the query)
  • Wikidata SPARQL query that lists all institutions with the number of Wikidata items that link to IIIF manifests (click the blue arrow button at the bottom left to run the query)
• In 2017-19, Wikimedia Commons is enhanced with structured data (read more about the Structured Data on Commons project). From 2019, better APIs for Wikimedia Commons offer more detailed technical possibilities for IIIF-driven applications.

Some initial thoughts by Tom Crane about IIIF integration for Wikimedia projects can be found on his Github.

IIIF tools and software for Wikimedia projects

Please add examples if you know about them!

Wikimedia Commons

• https://tools.wmflabs.org/zoomviewer/proxy.php?iiif= . Experimental IIIF Image service endpoint, in theory able to serve any Commons image, applying IIIF image API directives (via an installation of IIP Image, also used to offer javascript zoom-browsing of large images). Separate from MediaWiki's usual image scalers.
  • eg: https://tools.wmflabs.org/zoomviewer/proxy.php?iiif=Godward_Idleness_1900.jpg/pct:65,81,35,15/full/0/default.jpg
• IIIF Cropper on Crotos -- tool to define P2677 values, and display results.

Wikidata

• IIIF manifest URL (P6108) -- links Wikidata items of to their corresponding IIIF manifests hosted by cultural institutions
• relative position within image (P2677) -- Wikidata qualifier to specify location of details within artworks, using syntax based on IIIF Image API.
  • see, for example, d:Q17335769#P180.
• d:User:Husky/ifff-viewer-link.js (shows selected parts of images, according to P2677 qualifiers)
• d:User:Lucas Werkmeister/Wikidata Image Positions Examples:
  • The Coronation of Napoleon
  • Situation Room
  • Portrait of a Woman with a Squirrel
• IIIF Viewer in Wikidata - user script to display a IIIF viewer on a Wikidata item page if there is an IIIF manifest.
  • Original script: wikidata:User:Btwashburn/iiif-mirador.js
  • Variation that uses Mirador off Toolforge: wikidata:User:Fuzheado/toolforge-mirador.js
