  • 1. SharedCanvasDigital Manuscripts andInteroperability Across RepositoriesLIBER : promoting access to manuscript contentParis, BnF, may 2012
  • 2. How we started ?• Andrew W. Mellon Foundation funded numerous manuscript digitization projects over several decades• All had in common: – Inability to share data across silos to satisfy scholarly use – Inability to leverage existing infrastructure – No sustainability model for data or access• Goal: – Interoperability between repositories and tools
  • 3. Who’s involved ?• Repositories – Parker on the Web (Stanford) – Roman de la Rose (Johns Hopkins) – E-codices (Univ. Fribourg) – Gallica (BnF) – British Library – Bodleian Library• Tools – T-PEN – Digital MappaeMundi (Drew Univ.) – TILE (Univ. Of Maryland)
  • 4. What do we have now ? A world of silosRoman de la Rose E-codices Gallica And so on…
  • 5. Most digital libraries : what you can do ? • Access data from a single repository, and sometimes federate content through OAI • Use the tools that repository supports • See images in the way that repository allows (or jump to another digital library hosting federated content) • See curated descriptions of the material • See approved additional material • Search and browse to the library’s content and sometimes federated content
  • 6. What you can’t do…• Access data from any other repositories• Use any other tools• See images any other way (like comparing 2 manuscripts kept in 2 different digital libraries)• Contribute or correct descriptions (often)• Add additional material or comments (often)• Search across repositories unless federated search has been implemented
  • 7. Defining interoperability• Break down silos• Separate data from applications• Share data models and programming interfaces• Enable interactions at the tool and repository level• Use the content (images, records, transcriptions…) where they are without having to store multiple (manual) copies• Ensure visibility for all institutions/data providers

  • 9. What does SharedCanvas do ?• Provide, at the digital library level, a manifest : « here is what we have »• Give a standardized and highly detailed description of the digital document’s organization• If validated, link to any content generated about a manuscript, and/ or use it without having to store this content
  • 10. Open Annotation data model
  • 11. Multiple content types
  • 12. Rebinding example
  • 13. A few demos• Manifests for BNF Machaut manuscripts• http://dms-data.stanford.edu/BnF/• Images annotations of Morgan 804 • http://www.shared-canvas.org/impl/demo1/
