IIIF

The International Image Interoperability Framework (IIIF) is a set of open, community-developed technical specifications and APIs that enable cultural heritage institutions to share, access, and reuse digital image collections in a standardised way. IIIF provides an Image API (for accessing image pixels at specific sizes and regions), a Presentation API (for describing how images and their metadata should be displayed), and a Content Search API. By adopting IIIF, museums, libraries, and archives ensure their digital collections are interoperable and accessible across platforms — directly supporting the FAIR principles. IIIF is widely used by institutions including the British Library, the Smithsonian, Europeana, and major universities.
