SharedCanvas: A Collaborative Model for Medieval Manuscript Layout Dissemination Presentation Transcript

  • 1. SharedCanvas: A Collaborative Modelfor 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. MotivationDigitization of cultural heritage important•  Less than 1% of known medieval documents digitized to dateDigital 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. MotivationInnovation needed in modeling and rendering: •  Embrace the GraphInnovation in storage and inter-linking: •  Embrace the WebDesires:•  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 RequirementsGoal:•  Provide standardized input to presentation systems, to allow interoperability between manuscript repositoriesArchitectural 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 RequirementsWorking 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 Requirements2. 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 Requirements3. 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 Requirements4. 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 Requirements5. Multiple page orders over time•  Rebinding•  Scholarly disagreement on reconstruction6. 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 DirectlyBut 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 Annotations Target •  The Image/Text/Commentary is the Annotations 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
  • 13. Canvas to Page Relationship SharedCanvas: Collaborative Medieval Manuscript Model 13 JCDL 2011, Ottawa, June 13-17
  • 14. OAC Annotations to Paint Images SharedCanvas: Collaborative Medieval Manuscript Model 14 JCDL 2011, Ottawa, June 13-17
  • 15. OAC Annotations to Paint Text SharedCanvas: Collaborative Medieval Manuscript Model 15 JCDL 2011, Ottawa, June 13-17

  • 17. Transcription: M804SharedCanvas: Collaborative Medieval Manuscript Model 17 JCDL 2011, Ottawa, June 13-17
  • 18. Fragments: Cod Sang 1394 SharedCanvas: Collaborative Medieval Manuscript Model 18 JCDL 2011, Ottawa, June 13-17
  • 19. Missing Pages: Parker CCC 286 SharedCanvas: Collaborative Medieval Manuscript Model 19 JCDL 2011, Ottawa, June 13-17
  • 20. Repeated Zones: Frauenfeld Y 112 SharedCanvas: Collaborative Medieval Manuscript Model 20 JCDL 2011, Ottawa, June 13-17
  • 21. ORE Aggregations for Ordering SharedCanvas: Collaborative Medieval Manuscript Model 21 JCDL 2011, Ottawa, June 13-17
  • 22. Rebinding: BNF f.fr. 113-116 SharedCanvas: Collaborative Medieval Manuscript Model 22 JCDL 2011, Ottawa, June 13-17
  • 23. SharedCanvas: Data Model SharedCanvas: Collaborative Medieval Manuscript Model 23 JCDL 2011, Ottawa, June 13-17
  • 24. ImplementationsRepository Side: •  Parker Library on the Web (Stanford) •  Roman de la Rose (JHU) •  e-codicesTools: •  T-PEN (transcription tool) •  Digital MappaeMundi (annotation tool) SharedCanvas: Collaborative Medieval Manuscript Model 24 JCDL 2011, Ottawa, June 13-17
  • 25. ImplementationsClient Side:•  Flipbook integration for navigation•  Djatoka for pan/zoomNative implementation planned:•  Graph navigation•  Integratation of scholarlyannotations SharedCanvas: Collaborative Medieval Manuscript Model 25 JCDL 2011, Ottawa, June 13-17
  • 26. Conclusions•  Distributed Canvas paradigm provides a coherent solution tomodeling 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 humanists primary research objects to their desktop in apowerful, extensible and interoperable fashion SharedCanvas: Collaborative Medieval Manuscript Model 26 JCDL 2011, Ottawa, June 13-17
