IIIF (International Image Interoperability Framework) is a set of open standards for delivering high-quality digital images, audio and video across the web. IIIF, which originated in the GLAM sector, allows audiences to view, compare and interact with digital resources from different repositories.
The IIIF extension comes with an annotation tool based on OpenSeaDragon and Annotorious that lets you annotate IIIF resources and offers a parser function to facilitate the transformation of IIIF annotations (JSON) into subobjects. It is these subobjects that can then be visualised using the iiif-canvas-viewer and iiif-annotation-gallery result formats.
A number of printout properties are required to provide the necessary data. In order for those properties to get recognised by the data model, they must be (re-)labelled with the predefined names given below:
manifest- the Manifest URL is required primarily because we need to fetch data relating to Canvas items and reuse them in our new data resource.canvasid- the Canvas identifier (id/@id)xywh- the xywh values of the image regiontilesource- tile source identifier (without/info.json)profileid- required unless 'template' is used. Refers to the page ID of the 'profile' that was used to configure the annotation form. See below.
For more details, see the documentation on Special:IIIF that come with the extension.
