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

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

Naïve Approach: Transcribe Images Directly

But how to align multiple images, pages without images, fragments… ?!

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

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/

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
