A consortium of leading cultural institutions backing open standards for delivering digital objects online at scale.

The IIIF Consortium is an international community of cultural heritage institutions, research libraries, and technology organizations that develops and implements the International Image Interoperability Framework (IIIF). IIIF defines a set of open APIs providing standardized methods for describing and delivering images and structured metadata over the web, enabling interoperability across repositories holding artworks, books, manuscripts, maps, and archival materials. The consortium fosters a shared ecosystem of compatible servers, viewers, and annotation tools.
