Oculus: Using Open APIs to Share Harvard’s Digitized Books and Manuscripts

  1. 1. Oculus: Using Open APIs to Share Harvard’s Digitized Books and Manuscripts Harvard University IT Summit June 5, 2014
  2. 2. Our Speakers 2 Jud Harward, Director of Research Computing for the Arts and Humanities, Academic Technology Services, Harvard University Information Technology Jeffrey Hamburger, Kuno Francke Professor of German Art and Culture, Department of History of Art and Architecture, Harvard University Rashmi Singhal, Software Engineer, HarvardX Randy Stern, Director, Systems Development, Library Technology Services, Harvard University Information Technology Jeff Emanuel, Senior Project Lead (Instructional Development), HarvardX
  3. 3. How do you view digitized books and manuscripts? Page Delivery Service – the old browser version http://pds.lib.harvard.edu/pds/view/ 10840328?n=8&printThumbnails=true Slide thanks to Randy Stern

  5. 5. PDS Drawback 2: Old Fashioned Interface Contrast Chip Goines’ Tablet PDS (2012) http://pds.lib.harvard.edu/pds/ mobile/index.html?id=10840328 Slide thanks to Randy Stern
  6. 6. PDS Drawback 3: Difficulty in Adding Features 6 •  2 page view with opening •  Better ways to navigate a volume •  Support for layered views (e.g., image and transcription) •  Support for annotation •  Ability to compare documents from multiple archives and even to assemble “virtual” volumes
  7. 7. Project Timeline 7 •  July, 2012: Initial meetings with Jeffrey Hamburger •  November, 2012: Digital Arts and Humanities Committee charters working group •  February, 2013: Working group reports backs favoring implementation of new page viewer o  based on the Stanford-led Digital Medieval Manuscript Initiative o  open source and compliant with public APIs •  March – May 2013: discussions o  with HarvardX linking new page viewer with HarvardX History of the Book modules; o  with Library Technical Advisory Board •  June, 2013: Samantha Earp and Robert Lue of HarvardX commit funding for a 1 year developer •  December, 2013: Rashmi Singhal starts as principal Harvard developer of new Harvard viewer christened Oculus Concept & Requirements Politics Implementation
  8. 8. Risks vs Benefits of Oculus Strategy •  Risks: o  Large number of organizations involved with multiple handoffs in development: Stanford, HarvardX, Harvard LTS o  Many chefs, few cooks o  Harvard does not control all the decisions or resources •  Benefits o  Open source result built according to open standards o  Strong possibility of support via community process going forward o  Tool should be compatible with multiple archives 8

  19. 19. Library Technology Services goals •  Provide an improved book display user interface •  Expose digital content through standard APIs •  Position content for future uses (transcription, annotation) •  Collaborate more! •  within Harvard (building on the successful Tablet PDS collaboration) •  externally with peer institutions 19
  20. 20. Improved book display - Oculus
  21. 21. Improved book display - Oculus •  2 page view of book opening •  Full screen mode •  Annotation ready •  Ability to display Shared Canvas books from both the DRS and other institutions within the same U/I •  Modern javascript implementation
  22. 22. Open Harvard library digital content for reuse and allow Harvard to reuse external content •  A content delivery API (the digital book or digital image) •  not a metadata API (title, author, subject) Two pronged approach: •  Represent the physical object in a common data model •  (Shared Canvas) •  Deliver and receive data via a common API •  (IIIF – the International Image Interoperability Framework)
  23. 23. Common Data Model - Shared Canvas http://www.shared-canvas.org
  24. 24. Open Annotation http://www.openannotation.org/spec/core/
