IIIFThe International Image Interoperability Framework

• Standardized Web APIs for accessing digital images and collections together with presentation metadata• Opens Harvard library digital content for reuse over the Web• Allows Harvard to reuse external content

Sample Use Cases• Teaching: Displaying a “Virtual manuscript” where Harvard holds

some pages and Yale holds other pages• Research: Comparison of a Harvard and British Library copy of

the same work• Library or Museum: Creating on-line collections that include

material from multiple institutions

Library IIIF APIs

• Image API http://ids.lib.harvard.edu/ids/iiif/5981214/0,0,1200,1200/pct:50/full/native.jpg• Displays the image or image region that has been specified

• Presentation API• http://iiif.lib.harvard.edu/manifests/drs:5981093 • Returns a JSON manifest for a PDS object in the DRS

• The Mirador viewer uses both APIs

IIIF Ghent meetings• Dec 7-11 in Ghent Belgium• Day1 - introductory workshop on IIIFpecificatons with implementation guidance (

Session notes)• Day2 – Public event - overview of IIIF, introduction to the framework and its APIs,

case studies from adopters, demonstration of several IIIF-related software packages (Agenda with linked presentations)

• Day3 - community roundtable and unconference including demonstrations of new implementations and requirements, detailed review of upcoming updates to the technical specifications, and a straw poll of the most important areas of focus for 2016 as well as exploratory framing of how discovery of IIIF resources may work.

• Day 4 and 5 - extended sessions on… – Newspapers and IIIF– Mirador– the Universal Viewer

• a two-day meeting on medieval & renaissance manuscripts• a meeting of the IIIF Consortium’s Executive Committee & Editors Group.

Notes• The IIIF APIs are expected to see releases in 2016

– the Image and Presentation API are expected to see minor changes in versions 2.1 of each in early 2016

– two new APIs, Authentication and Search Within, are anticipated for 0.9 release in May 2016.

• Two new interest groups formed for applying IIIF to specific content types. – Newspapers Interest Group will begin calls in January of 2016,

convened by Karen Estlund (Penn State) and Alistair Dunning (Europeana).

– Medieval / Renaissance Manuscripts, convened by Ben Albritton (Stanford). Monthly calls, including a charter and call for participation, will begin in early 2016.

Notes• Future IIIF work priorities identified and prioritized

(score in paranthesis) by those in attendance included… – extending the IIIF APIs to include full CRUD operations via

REST (30)– support for non-image content (23)– discovery of IIIF resources (23)– identifying best practices for linking, modeling, versioning

(16)– improvements to IIIF documentation, website, training and

support for new adopters (16) – enhancements to existing APIs (~15)– better description of IIIF clients (5)

Notes• Demonstrations of new or prospective IIIF-compatible software included:

– Diva.js, document viewer– Cantus Ultimus, optical music recognition project– Rosetta, the Ex Libris digital preservation tool, with a IIIF viewer– Shimmy, a tool for generating presentation API manifests– Berlin State Library– Qatar Digital Library– Fragmentarium, a Swiss project to re-assemble manuscript leaves from fragments– Digital Bodleian, Oxford’s IIIF-enabled digital collections viewer (including drag and

drop)– Harvard’s digital library systems– Freizo, developed at Westminster as a tool for scanning & annotating research

notebooks– Codex Sinaitcus– Universal Viewer, including use of the IIIF Search API– Reconstructed manuscripts / rejoined collections and TEI annotations from the

Biblissima project

IIIF Consortium• The IIIF Consortium, formed in June of 2015,

has begun circulating a call for additional Founding Members.

• Now around 20 members – including Harvard

Medieval Manuscripts• Bill Stoneman

Mirador working group• Chip Goines

Newspaper Interest Group• 25 attendees• Chairs: Karen Estlund (Penn State) and Alastair Dunning (Europeana)• Example newspaper display at National Library of Wales -

http://newspapers.library.wales/view/3306032 • Data modeling

Newspaper Interest Group• OCR Correction• -Users correcting OCR (losing or not losing coords after transcription/correction)• -Recognizing identity of annotator• -Scholarly transcription vs Public transcription• • Annotation Use Cases• OCR/transcription Edit

– improve search and display– accessibility, usability– OCR training

• Comments user generated• Hotspot linking• Semantic tagging• Article segmenter - article, illustrations, etc.• Serialization• • Federated Search• • Aggregation vs Distributed Search• IIIF registry needed to expose IIIF resources of type newspaper, perhaps with other attributes• Need for discovery systems that point to collections, that may or may not have search services.• Issues with both.
