Transcending Silos: Shared Canvas Data Model for Digital Facsimiles
•
2 likes•1,815 views
The document proposes a linked data model called SharedCanvas to collaboratively access digital facsimiles of manuscripts. SharedCanvas uses a "canvas paradigm" where resources like images, text, and annotations are associated with areas on a virtual canvas corresponding to manuscript pages. It models manuscripts using primarily the Open Annotation data model to paint resources onto canvases. This allows distribution of resources across repositories while bringing digitized works together in an extensible, interoperable way.

Requirements: • Need to allow distributed association of resources with the Canvas, or part of the Canvas • Any type of resource, or part of a resource, should be able to be painted • Need to allow users to comment about the Canvas, or part of it, or any of the resources Solution: • Associate resources and commentary using Open Annotations!
