SharedCanvas: Collaborative Medieval Manuscript Model 1
JCDL 2011, Ottawa, June 13-17
2. Overview
• Motivation
• Requirements / Use Cases
• Model by Example
• Implementations
• Conclusion
SharedCanvas: Collaborative Medieval Manuscript Model 2
JCDL 2011, Ottawa, June 13-17
3. Motivation
Digitization of cultural heritage
important
• Less than 1% of known medieval
documents digitized to date
Digital surrogates enable remote
research
• Improve preservation of original and
surrogate
• Enable collaboration via shared
annotation
BNF f.fr 113, folio 1 recto

4. Motivation
Innovation needed in modeling and
rendering:
• Embrace the Graph
Innovation in storage and inter-linking:
• Embrace the Web
Desires:
• Rich landscape of interconnected
repositories
• Improve efficiency through shared
development

5. Architectural Requirements
Goal:
• Provide standardized input to presentation systems,
to allow interoperability between manuscript repositories
Architectural Requirements:
• Ability to model primarily textual items, where the individual
physical instance is an important cultural object
• Alignment of Images, Texts and Commentary per page
• Services and Content distributed between institutions

6. Domain Requirements
Working at physical item level
provides unique challenges!
1. Only parts of pages may be
digitized
• Only illuminations digitized
• Fragments of pages
• Multiple fragments per
image
Cod. Sang. 1394: 10.5076/e-codices-csg-1394

JCDL 2011, Ottawa, June 13-17
7. Domain Requirements
2. Page may not be digitized at
all
• Not "interesting" enough This page intentionally,
• Digitization destructive but unfortunately,
left blank
• Page no longer exists
• Page only hypothetical

8. Domain Requirements
3. Non-rectangular pages
• Fashionable heart shaped
manuscripts
• Fragments
• Pages with foldouts

9. Domain Requirements
4. Alignment of multiple
images of same object
• Multi-spectral imaging
• Multiple resolutions
• Image tiling
• Microfilm vs photograph
• Multiple digitizations

JCDL 2011, Ottawa, June 13-17
10. Domain Requirements
5. Multiple page orders over time
• Rebinding
• Scholarly disagreement on
reconstruction
6. Different pages of the manuscript
held by different institutions

11. Initial Approach: Transcribe Images Directly
But how to align multiple images, pages without images, fragments ???

12. Canvas and Annotation Paradigm
• A generic Canvas is an abstract space to build up a display
• HTML5, SVG, PDF, UI layout in software … even Powerpoint!
• Our Canvas starts with no content, but has rectangular aspect ratio
• Top left/bottom right corner of canvas is equivalent corner of
rectangular bounding box around page
• Images and Text painted on to Canvas by distributed Annotation
• The Canvas is the Annotation's Target
• The Image/Text/Commentary is the Annotation's Body
• Both Body and Target support Segment descriptions:
• Fragments
• Extract page/line text from full transcription

24. Implementations
Repository Side:
• Parker Library on the Web
(Stanford)
• Roman de la Rose
(JHU)
• e-codices
Tools:
• T-PEN
(transcription tool)
• Digital MappaeMundi
(annotation tool)

25. Implementations
Client Side:
• Flipbook integration for navigation
• Djatoka for pan/zoom
Native implementation planned:
• Graph navigation
• Integratation of scholarly
annotations

26. Conclusions
• Distributed Canvas paradigm provides a coherent solution to
modeling the layout of medieval manuscripts
• Distributed Annotations across repositories for text, image and
scholarly commentary
• Annotations at the heart of the model
• Thus: Collaboration at the heart of the model
• Granular accuracy, from resource to non-rectangular segment
• Multiple page orders and Discovery via Aggregations
• Likely appropriate for non Medieval Manuscript applications
• Scrolls, Newspapers, Scientific papers, … ?
• Brings the humanist's primary research objects to their desktop in a
powerful, extensible and interoperable fashion
