What is Shared Canvas?
● A linked data specification for collaboratively describing digital representations of physical objects.
● Resources are given relationships to canvases by Open Annotations[1] and are grouped via OAI-ORE Aggregations[2].

○ External PHP script that adds a Shared Canvas data stream to each manuscript object using Tuque
○ Script is triggered manually after batch uploads of objects
■ Shared Canvas generated at the book object level
■ Shared Canvas references not the high resolution TIFFs for each page ingested into Islandora but instead a lower-resolution JPEG derivative that has a fixed height of 2000 px that is optimal for T-PEN

Generating Shared Canvas Manifests

Sending Shared Canvas to T-PEN
● T-PEN[3] is an open source Java application developed by Saint Louis University
○ A customized variant was deployed locally for this project
● Exposes a RESTful API for handling transcription
○ Requires non-interactive authentication
● Due to project constraints Single Sign On (SSO) was not able to be implemented in the first sprint
○ Interim-Solution? Magic, Session Magic
○ When a logged in user wants to work on transcriptions the user is automatically re-authenticated
via their session ID in both T-PEN and Islandora

About our future plans for IIIF
● T-PEN doesn’t require IIIF compliance for its images which allowed us to focus the first sprint of the
project on implementing Shared Canvas
● HOWEVER, the project investigator at Newberry does not like the Internet Archive BookReader viewer
● T-PEN uses Mirador[4], Newberry folks are also encouraging use of Mirador
● For our next project phase we will be integrating Mirador into Islandora

Integrating IIIF for the Paleography project
● JPEG2000 (JP2) support
○ The only current efficient support is via Kakadu[5] a commercially licensed C++ JP2 library
○ Open source initiative OpenJPEG[6] is trying to improve efficiency[7] to become a viable
alternative
● Servers under consideration
○ All listed servers come bundled with an evaluation binary of Kakadu for non-commercial or
evaluation uses. Compiling new versions requires a license for Kakadu
○ IIPImage Server[8]
■ Requires a physical file path to the image; problematic for some configurations
○ Djatoka[9]
■ Requires a translation layer to transform IIIF urls to Djatoka urls

● Servers under consideration (continued)
○ Lorris[10]
■ Written in Python
■ Can utilize data-streams as well as physical file paths
● Mirador integration is only funded for Paleography project.
● Any “full” integration will require understanding and responding to both Djatoka and IIIF syntax
