IIIF Universal Viewer

The Universal Viewer is a popular IIIF viewer particularly prevalent in National Cultural Heritage Institutions. It is a plugin for Omeka CMS that adds the IIIF specifications in order to serve images like a simple image server, similar to a basic IIP Image, and the UniversalViewer, a unified online player for any file. It can display books, images, maps, audio, movies, pdf, 3D, and anything else as long as the appropriate extension is installed. Rotation, zoom, inside search, etc. may be managed too. Dynamic lists of records may be used, for example for browse pages.

The Universal Viewer supports the IXIF media extension too, so manifests can be served for any type of file. For non-images files, it is recommended to use a specific viewer or the Universal Viewer, a widget that can display books, images, maps, audio, movies, pdf, 3D, and anything else as long as the appropriate extension is installed.

The Universal Viewer was firstly developed by Digirati for the Wellcome Library of the British Library and the National Library of Wales, then open sourced.
