Viewer Matrix

IIIF 3.0 Viewer Matrix

In the 2021 Working meeting there was a presentation on viewer support for IIIF 3.0 and the community asked if this presentation could be turned into a matrix so the community can see which viewers support which area of the IIIF specifications. This matrix is generated automatically from the recipes and if you notice any thing that is incorrect please report it to the cookbook GitHub site.

Which viewers are included?

Currently Mirador 3, the Universal Viewer (UV) V3, Annona, Clover, Navplace Viewer, and Ramp are listed on the cookbook and we welcome the addition of other IIIF viewers but they must support the following features:

Geo Recipes

Please note there are many viewers built to view GeoJSON like Leaflet and geojson.io. These viewers do not know to parse objects for a navPlace property or look into the body property of Annotations for GeoJSON. However, they are easily customizable and can be made to find GeoJSON in these properties. The Navplace Viewer is an Open Source customization which intelligently gathers and formats GeoJSON from provided IIIF resources and hands that GeoJSON to a Leaflet viewer for rendering.
