[$] IIIF: images and visual presentations for the web

The International Image InteroperabilityFramework, or IIIF ("triple-eye eff"), is a small set of standards thatform a basis for serving, displaying, and reusing image data on the web. Itconsists of a number of API definitions that compose with each other toachieve a standard for providing, for example, presentations ofhigh-resolution images at multiple zoom levels, as well as bundling multiple imagestogether. Presentations may include metadata about details like authorship,dates, references to other representations of the same work, copyrightinformation, bibliographic identifiers, etc. Presentations can be furthergrouped into collections, and metadata can be added in the form oftranscriptions, annotations, or captions. IIIF is most popular withcultural-heritage organizations, such as libraries, universities, andarchives.
