SharedCanvas: A Collaborative Model for Medieval Manuscript Layout Dissemination
- 1. SharedCanvas: A Collaborative Model for Medieval Manuscript Layout Dissemination Robert Sanderson rsanderson@lanl.gov Los Alamos National Laboratory Benjamin Albritton Stanford University Rafael Schwemmer e-codices Herbert Van de Sompel Los Alamos National Laboratory http://www.shared-canvas.org/ This research is funded, in part, by the Andrew W. Mellon Foundation 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 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
