2. Overview
• SharedCanvas:
• Requirements
• Model by Example
• Evaluation in CATCHPlus:
• Use Cases
• Modeling

3. Motivation
Manuscripts spread all around the world:
• For every repository, its interface.
• How do we rethink digital facsimiles in a
shared, distributed, global space?
A collaborative future:
• Rich landscape of interconnected
repositories, with seamless user
interfaces
• Improve efficiency and usability through
open, shared development

4. Baseline Requirements
To Realize this Future:
• Need an interoperable input format to
presentation systems, exposed by
distributed repositories
Baseline Requirements:
• Ability to model primarily textual items,
where the individual physical instance is
an important cultural object
• Alignment of multiple Images, Texts,
Commentary and other Content
resources per folio

9. Naïve Approach: Transcribe Images Directly
But how to align multiple images, pages without images, fragments… ?!

10. Canvas Paradigm
• A Canvas is an empty space in which to build up a display
• A SharedCanvas's top left and bottom right corners correspond to
the equivalent corners of a page

11. Painting the Canvas?
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 using Annotations
• Open Annotation: http://www.openannotation.org/

29. Summary
Distributed Canvas paradigm provides a coherent solution to modeling
the layout of medieval manuscripts
• Annotation, and Collaboration, at the heart of the model
• Distribution across repositories for images, text, commentary
• Granular accuracy, from full resource to non-rectangular segment
• Multiple page orders and Discovery via Aggregations
SharedCanvas brings the humanist's primary research objects
to their desktop in a powerful, extensible and interoperable fashion
