SharedCanvas: Collaborative Digital Facsimiles of Medieval Manuscripts

  1. 1. SharedCanvas: Collaborative Digital Facsimiles of Medieval Manuscripts Robert Sanderson rsanderson@lanl.gov Los Alamos National Laboratory Collaborators: Benjamin Albritton Hennie Brugman Rafael Schwemmer Herbert Van de Sompel http://www.shared-canvas.org/ This presentation arises from work funded, in part, by the Andrew W. Mellon Foundation SharedCanvas: Collaborative Manuscript Facsimiles 1 Digital Manuscript Workshop, 21st Nov 2011, Ghent, Belgium
  2. 2. Overview•  Motivation•  Requirements from Manuscripts•  SharedCanvas Model by Example•  Further Modelling Issues•  Distributed Approach SharedCanvas: Collaborative Manuscript Facsimiles 2 Digital Manuscript Workshop, 21st Nov 2011, Ghent, Belgium
  3. 3. MotivationThere are many repositories of digitized books, manuscripts and other culturally important objects.And just as many home-grown page turning websites, apps and programs.Plus at least as many formats for description.Even for a quires or folios of a single manuscript, held at different physical locations! Ms MurF: 10.5076/e-codices-kba-0003 SharedCanvas: Collaborative Manuscript Facsimiles 3 Digital Manuscript Workshop, 21st Nov 2011, Ghent, Belgium
  4. 4. VisionA collaborative future: •  Rich landscape of interconnected repositories of images, texts, media •  Seamless user interfaces disconnected from those repositories •  Improved efficiency and usability through open, shared developmentRequirements: •  Shared Data Model •  Shared services BNF f.fr 113, folio 1 recto SharedCanvas: Collaborative Manuscript Facsimiles 4 Digital Manuscript Workshop, 21st Nov 2011, Ghent, Belgium
  5. 5. 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 Manuscript Facsimiles 5 Digital Manuscript Workshop, 21st Nov 2011, Ghent, Belgium
  6. 6. 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 Countless manuscripts, all around the world! SharedCanvas: Collaborative Manuscript Facsimiles 6 Digital Manuscript Workshop, 21st Nov 2011, Ghent, Belgium
  7. 7. Domain Requirements3. Non-rectangular objects•  Fashionable heart shaped manuscripts•  Fragments•  Pages with foldouts Facsimile of BNF Rothschild 2973 http://www.omifacsimiles.com/brochures/montchen.html SharedCanvas: Collaborative Manuscript Facsimiles 7 Digital Manuscript Workshop, 21st Nov 2011, Ghent, Belgium
  8. 8. 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 Manuscript Facsimiles 8 Digital Manuscript Workshop, 21st Nov 2011, Ghent, Belgium
  9. 9. 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 Manuscript Facsimiles 9 Digital Manuscript Workshop, 21st Nov 2011, Ghent, Belgium
  10. 10. Domain Requirements7. Transcription of: •  Text •  Music •  Musical Notation •  Performance •  Diagrams Reusing existing resources, such as TEI, where possible but …8. … Allowing new transcriptions to be both created and stored in a distributed way, with competing versions Parker CCC 008, f1r SharedCanvas: Collaborative Manuscript Facsimiles 10 Digital Manuscript Workshop, 21st Nov 2011, Ghent, Belgium

  20. 20. 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 resourcesCombined Solution: •  Associate resources using Annotations •  Open Annotation: http://www.openannotation.org/ SharedCanvas: Collaborative Manuscript Facsimiles 20 Digital Manuscript Workshop, 21st Nov 2011, Ghent, Belgium

  45. 45. SummaryModel: •  Canvas paradigm provides a coherent solution to modeling the layout of medieval manuscripts •  … or any other, collaboratively created resourceImplementation: •  Distribution across repositories for all resources •  PubSub enables customized views and avoids tool lock-in •  Encourages development by domain experts SharedCanvas brings digitized works to the desktop in a powerful, extensible and interoperable fashion SharedCanvas: Collaborative Manuscript Facsimiles 45 Digital Manuscript Workshop, 21st Nov 2011, Ghent, Belgium
