Overview

•  SharedCanvas: •  Requirements •  Model by Example

•  Evaluation in CATCHPlus: •  Use Cases •  Modeling


3

Motivation

Manuscripts spread all around the world: •  For every repository, its interface. •  How do we rethink digital facsimiles in a

shared, distributed, global space?

A collaborative future: •  Rich landscape of interconnected

repositories, with seamless user interfaces

•  Improve efficiency and usability through open, shared development

BNF f.fr 113, folio 1 recto


4

Baseline Requirements

To Realize this Future: •  Need an interoperable input format to

presentation systems, exposed by distributed repositories

Baseline Requirements: •  Ability to model primarily textual items,

where the individual physical instance is an important cultural object

•  Alignment of multiple Images, Texts, Commentary and other Content resources per folio

5

Domain Requirements: Missing/Fragmentary Pages

Cod. Sang. 1394: 10.5076/e-codices-csg-1394

This page intentionally, but unfortunately,

left blank


6

Domain Requirements: Non-Rectangular Fragments/Pages

Facsimile of BNF Rothschild 2973 http://www.omifacsimiles.com/brochures/montchen.html Cod Sang 1394, folio 63r


7

Domain Requirements: Multiple Orderings and Digitizations

Archimedes Palimpsest Multi-Spectral Images http://www.archimedespalimpsest.org/ Cod Sang 730: 10.5706/e-codices-csg-0730a

Domain Requirements: Non-Text

Naïve Approach: Transcribe Images Directly

But how to align multiple images, pages without images, fragments… ?!


10

Canvas Paradigm

•  A Canvas is an empty space in which to build up a display •  A SharedCanvas's top left and bottom right corners correspond to the equivalent corners of a page


11

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 resources

Solution: •  Associate resources using Annotations •  Open Annotation: http://www.openannotation.org/

Discovery

Evaluation via Unseen Requirements

Archive of the Queen’s Office (KdK)

•  40,000 images with transcriptions

•  Texts automatically annotated with Named Entity software

•  Templates for consistent layouts


20

Evaluation via Unseen Requirements

Sailing Letters

•  38,000 letters and documents captured by Pirates

•  Complex layouts

•  Multiple co-ordinates after image re-alignment

•  Alignment of multiple texts (transcription versus edition)

Alignment of Multiple Texts

Group text annotations together in the Discovery layer Align via overlap of Annotation targets on the Canvas

Summary

Distributed Canvas paradigm provides a coherent solution to modeling the layout of medieval manuscripts

•  Annotation, and Collaboration, at the heart of the model •  Distribution across repositories for images, text, commentary •  Granular accuracy, from full resource to non-rectangular segment •  Multiple page orders and Discovery via Aggregations

SharedCanvas brings the humanist's primary research objects to their desktop in a powerful, extensible and interoperable fashion
