Transcending Silos: Shared Canvas Data Model for Digital Facsimiles

  1. 1. Transcending Silos: Linked Data Model forCollaborative Access to Digital Facsimiles Robert Sanderson rsanderson@lanl.gov Los Alamos National Laboratory @azaroth42 Benjamin Albritton, Tom Cramer {blalbrit,tcramer}@stanford.edu Stanford University @bla222, @tcramer http://www.shared-canvas.org/ Transcending Silos: Shared Canvas 1 DLF Forum 2012, November 4-5, Denver CO, USA
  2. 2. Overview•  Data Model Requirements•  SharedCanvas Model by Example•  Further Modelling Issues•  Non Manuscript Examples Transcending Silos: Shared Canvas 2 DLF Forum 2012, November 4-5, Denver CO, USA
  3. 3. Data Model 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•  Information about non- digitized parts may still exist Cod. Sang. 1394: 10.5076/e-codices-csg-1394 Transcending Silos: Shared Canvas 3 DLF Forum 2012, November 4-5, Denver CO, USA
  4. 4. Data Model 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! Transcending Silos: Shared Canvas 4 DLF Forum 2012, November 4-5, Denver CO, USA
  5. 5. Data Model Requirements3. Non-rectangular objects•  Fashionable heart shaped manuscripts•  Fragments•  Pages with foldouts Facsimile of BNF Rothschild 2973 http://www.omifacsimiles.com/brochures/montchen.html Transcending Silos: Shared Canvas 5 DLF Forum 2012, November 4-5, Denver CO, USA
  6. 6. Data Model 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/ Transcending Silos: Shared Canvas 6 DLF Forum 2012, November 4-5, Denver CO, USA
  7. 7. Data Model Requirements5. Multiple page orders over time•  Rebinding•  Scholarly disagreement on reconstruction6. Pages of the manuscript held by different institutions, in different countries, with different metadata, digitized in different ways, … Cod Sang 730: 10.5706/e-codices-csg-0730a Transcending Silos: Shared Canvas 7 DLF Forum 2012, November 4-5, Denver CO, USA
  8. 8. Data Model Requirements7. Transcription of: •  Text •  Music •  Musical Notation •  Performance •  Diagrams8. Plus scholarly commentary on all of the above resources Parker CCC 008, f1r Transcending Silos: Shared Canvas 8 DLF Forum 2012, November 4-5, Denver CO, USA

  17. 17. 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 resourcesSolution: •  Associate resources and commentary using Open Annotations!

  38. 38. SummaryModel: •  Canvas paradigm provides a coherent solution to modeling the layout of medieval manuscripts •  … or any other, collaboratively created resource •  Using primarily OAI-ORE and Open Annotation constructionsImplementation: •  Distribution across repositories for all resources •  Encourages development by domain experts SharedCanvas brings digitized works to the desktop in a powerful, extensible and interoperable fashion Transcending Silos: Shared Canvas 38 DLF Forum 2012, November 4-5, Denver CO, USA
