Library of Congress Labs, Artist in Residency program project. Speculative Annotation.

Speculative Annotation is a web browser application written in Javascript and built with React, FabricJS, IIIF, OpenSeaDragon, and ChakraUI. Source images are hosted locally. The application uses the OpenSeadragon Viewer to render images, so your source images can be a combination of locally hosted images (within the application), or externally hosted images (for example, served from a IIIF image server).Application metadata is represented by a combination of local IIIF Presentation API 3.0 manifest files, and Library of Congress hosted IIIF manifest files. The application allows users to annotate select free to use items from the Library of Congress, save to browser or download locally.
