SharedCanvas: Dealing with Uncertainty in Digital Facsimiles

  1. 1. SharedCanvas: Dealing with UncertaintyApril 18 2013, The Hague, Netherlands1SharedCanvas: Dealing with Uncertainty in Digital FacsimilesRobert Sandersonrsanderson@lanl.govLos Alamos National Laboratory@azaroth42Benjamin Albrittonblalbrit@stanford.eduStanford University@bla222http://www.shared-canvas.org/This research was primarily funded by the Andrew W. Mellon Foundation
  2. 2. SharedCanvas: Dealing with UncertaintyApril 18 2013, The Hague, Netherlands2Overview•  Rethinking Digital Facsimiles•  SharedCanvas Model•  Issues:•  Multiplicity of Resources, Authors and States•  Uncertainty•  Implementation (if time)•  Or ask me for a demo :)
  3. 3. SharedCanvas: Dealing with UncertaintyApril 18 2013, The Hague, Netherlands3Digital FacsimilesMedieval manuscripts are increasingly beingdigitized:•  Preservation•  Mitigate against physical disaster•  Reduce need to handle original•  Ease of Access•  No need to travel to the manuscript•  Digital Exhibitions for the public•  Good Will•  Open licenses for reuseBNF f.fr 113, folio 1 recto
  4. 4. SharedCanvas: Dealing with UncertaintyApril 18 2013, The Hague, Netherlands4Digital FacsimilesThe Andrew W. Mellon Foundation funded many such projects.Lots of aspects in common:•  Held digitized images of medieval manuscripts•  Inability to share data between systems•  Inability to leverage existing infrastructure•  No sustainability model•  All reinvented the page-turning wheel•  Only for their images•  Only with their features•  Consume only, no interaction•  Expensive to maintain
  5. 5. SharedCanvas: Dealing with UncertaintyApril 18 2013, The Hague, Netherlands5Project StatusFirst 2 years of Mellon funding:•  Enlist partners•  Gather requirements•  Design data model•  Build proof of concept implementation (rendering)•  Engage with scholars and further communitiesCurrent funding:•  More partners•  Slick front end (UI, UX) [July]•  Annotation management [November]•  Validation with scholars [ongoing]

  9. 9. SharedCanvas: Dealing with UncertaintyApril 18 2013, The Hague, Netherlands9Baseline RequirementsBasic requirement assumptions:•  Transcribe a Text•  … From an Image•  Display Image+Text•  … In the correct order•  Allow commentaryUse Cases revealed two issues:•  Multiplicity•  UncertaintyMs MurF: 10.5076/e-codices-kba-0003
  10. 10. SharedCanvas: Dealing with UncertaintyApril 18 2013, The Hague, Netherlands10Model: Canvas Paradigm• A Canvas is an empty space in which to build up a display
  11. 11. SharedCanvas: Dealing with UncertaintyApril 18 2013, The Hague, Netherlands11Model: Canvas Paradigm• A Canvas is an empty space in which to build up a display• A SharedCanvass top left and bottom right corners correspond tothe equivalent corners of a [rectangular bounding box around a] page
  12. 12. SharedCanvas: Dealing with UncertaintyApril 18 2013, The Hague, Netherlands12Model: Annotations to Paint Canvas•  The Canvas represents the empty page•  Annotation links Image with Canvas

  15. 15. SharedCanvas: Dealing with UncertaintyApril 18 2013, The Hague, Netherlands15Naïve Assumption: Only One ImageAlignment of multipleimages of same object•  Multi-spectral imaging•  Multiple resolutions•  Image tiling•  Microfilm vs photograph•  Multiple digitizationsBonus naïvete:•  Page has 1 orientation•  Page has 1 text Archimedes Palimpsest Multi-Spectral Imageshttp://www.archimedespalimpsest.org/

SharedCanvas: Dealing with UncertaintyApril 18 2013, The Hague, Netherlands18Naïve Assumption: Image ExistsThe page may not be digitized•  Not "interesting" enough•  Digitization destructive•  Page no longer exists•  Page only hypothetical•  Lack of money, time, …This page intentionally,but unfortunately,left blankCountless manuscripts, all around the world!
