Since 2022, we have been working to bring multimodal annotation features to the IIIF community using Mirador. This allowed the creation of Manifest collection navigation interfaces, in the form of interactive network graphs, that we presented as a prototype at the IIIF Conference 202322. Since, we have continued development to keep up with recent Mirador updates to MUI5 and React17. The first prototype led to two contributions: a new plugin which is a major refactor and update of an image annotation plugin33 that now supports video and audio; an online multi-user platform called Arvest44, that will be publicly available as of September 2024. Arvest, combined with Mirador and our annotation plugin, proposes a IIIF-driven environment for the creation and navigation of multimodal document networks. The users can navigate collections of images, video, audio and documents through annotations of different natures – from textual captions and image annotations, to annotations that are linked to other Manifests. A project in Arvest is represented as a IIIF Collection of Manifests, meaning that full interoperability is still insured.
