SharedCanvas: A Collaborative Model for Medieval Manuscript Layout Dissemination
6 likes2,125 views
The SharedCanvas model aims to enhance the digital representation and collaboration on medieval manuscripts through standardized input to presentation systems. It addresses the complex challenges of digitizing partial, fragmented, and varying formats of manuscripts while promoting an architecture for distributed annotations across institutions. This approach enables more effective preservation, research collaboration, and interlinking of cultural heritage resources.

- 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 SharedCanvas: Collaborative Medieval Manuscript Model 3 JCDL 2011, Ottawa, June 13-17
- 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 Ms MurF: 10.5076/e-codices-kba-0003 SharedCanvas: Collaborative Medieval Manuscript Model 4 JCDL 2011, Ottawa, June 13-17
- 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 SharedCanvas: Collaborative Medieval Manuscript Model 5 JCDL 2011, Ottawa, June 13-17
- 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 SharedCanvas: Collaborative Medieval Manuscript Model 6 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 SharedCanvas: Collaborative Medieval Manuscript Model 7 JCDL 2011, Ottawa, June 13-17
- 8. Domain Requirements 3. Non-rectangular pages • Fashionable heart shaped manuscripts • Fragments • Pages with foldouts Facsimile of BNF Rothschild 2973 http://www.omifacsimiles.com/brochures/montchen.html SharedCanvas: Collaborative Medieval Manuscript Model 8 JCDL 2011, Ottawa, June 13-17
- 9. Domain Requirements 4. Alignment of multiple images of same object • Multi-spectral imaging • Multiple resolutions • Image tiling • Microfilm vs photograph • Multiple digitizations Archimedes Palimpsest Multi-Spectral Images http://www.archimedespalimpsest.org/ SharedCanvas: Collaborative Medieval Manuscript Model 9 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 Cod Sang 730: 10.5706/e-codices-csg-0730a SharedCanvas: Collaborative Medieval Manuscript Model 10 JCDL 2011, Ottawa, June 13-17
- 11. Initial Approach: Transcribe Images Directly But how to align multiple images, pages without images, fragments ??? SharedCanvas: Collaborative Medieval Manuscript Model 11 JCDL 2011, Ottawa, June 13-17
- 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 SharedCanvas: Collaborative Medieval Manuscript Model 12 JCDL 2011, Ottawa, June 13-17

- 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) SharedCanvas: Collaborative Medieval Manuscript Model 24 JCDL 2011, Ottawa, June 13-17
- 25. Implementations Client Side: • Flipbook integration for navigation • Djatoka for pan/zoom Native implementation planned: • Graph navigation • Integratation of scholarly annotations SharedCanvas: Collaborative Medieval Manuscript Model 25 JCDL 2011, Ottawa, June 13-17
- 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 SharedCanvas: Collaborative Medieval Manuscript Model 26 JCDL 2011, Ottawa, June 13-17
