The International Image Interoperability Framework, or IIIF, is a framework that specifies common interfaces for interacting with images on the Web. It provides an open framework for organizations to publish their image-based resources, to be viewed, cited, annotated, and more by any compatible image-viewing application

More and more institutions are adopting the use of IIIF to make their images and metadata more accessible and interoperable with other systems. More information can be found at the IIIF homepage.
