Why IIIF? Shane Huddleston Jeff Mixter Dave Collins Product Manager CONTENTdm Users Group – August 1, 2018 Why IIIF? Shane Huddleston Jeff Mixter Dave Collins Product Manager OCLC Software Engineer OCLC Consulting Software Engineer OCLC

IIIF is the International Image Interoperability FrameworkTM An emerging web standard for sharing information about images and other media​ Simplifies and standardizes the ways we ask for and consume media data

What does that mean? Shared API for access to images Shared API for access to record structure and metadata Shared content viewers Best practices for data management manuscripts newspapers much more

What else? “The IIIF is driven by a community of research, national and state libraries, museums, companies and image repositories committed to providing access to high quality image resources.” source: https://iiif.io/

IIIF is a community Regular working group conference calls Conferences and meetups (see https://iiif.io/event/) Mailing list & Slack team IIIF Consortium This engagement is how it succeeds.

How does IIIF work? Four APIs (for now) Image Presentation Authentication Search

IIIF Image API Request technical information (width, height, scaling) Request scaled images or portions of images Often supports rotation, image formats Create a complete image viewer, like OpenSeadragon Images for any UI (thumbnails, galleries, etc.)

Building an Image API request {protocol} :// {domain} / {prefix} / {identifier} / {region} / {size} / {rotation} / {quality} . {format} https://sandbox.contentdm.oclc.org/ digital/iiif/ p10010coll1/42/ full/full/ 0/ default.jpg https://sandbox.contentdm.oclc.org/digital/iiif/p10010coll1/18/full/full/0/default.jpg

Using the Image API Use Image API calls like any other image <img src= "https://sandbox.contentdm.oclc.org/digital/iiif/p10010coll1/ 18/full/full/0/default.jpg"> For example: https://cdmdemo.contentdm.oclc.org/digital/custom/image-api-calls Experiment: https://www.learniiif.org/image-api/playground

IIIF Presentation API Provides structural data about records Managing annotations Enough metadata for display in a user interface Other systems do not need to understand and parse metadata schemas https://sandbox.contentdm.oclc.org/digital/collection/p10010coll1/id/28 https://sandbox.contentdm.oclc.org/digital/iiif-info/p10010coll1/28

IIIF Authentication API “pattern for interacting with arbitrary third party protocols” Presenting authentication to users and applications Not a replacement for the actual authentication process CAS; OAuth2 Not implemented in CONTENTdm

IIIF Search API Searching within a given IIIF record E.g. full text search within a digitized manuscript Search focuses on IIIF Annotations OCR text User contributed information Not implemented in CONTENTdm

IIIF and the world of tomorrow!

The future of the IIIF Community

IIIF Community Groups There are 6 IIIF Community Groups Develop best practices and use cases around existing IIIF APIs Newspapers Community Group 3D Community Group Manuscripts Community Group Museums Community Group Outreach Community Group Software Developers Community Group

IIIF Consortium The Consortium is growing! https://iiif.io/community/consortium/

IIIF Managing Director IIIF Consortium is looking for a Managing Director https://www.clir.org/about/positions/iiif/

Annual Working Group Meeting December 3-6 in Edinburgh Scotland https://iiif.io/event/2018/edinburgh/ Mostly technical Voting on new API versions and work of the Technical Groups

Annual IIIF Meeting TBD but will be in May, 2019 somewhere in Europe More generalized IIIF talks/presentations

The future of IIIF API development

IIIF Technical Working Groups There are 3 IIIF Technical Specification Groups Focused on development of the new/existing APIs Discovery Technical Specification Group A/V Technical Specification Group Text Granularity Technical Specification Group

Continued API Refinement Presentation API 3.0 Image API 3.0

Presentation API 3.0 Support for Video and Audio! Alpha Draft Need to account for time and space in the data model Alpha Draft

Image API 3.0 Support for Video and Audio! Encode audio and video technical information in the data Fix some API oddities and irregularities …!?!? Do things better and in a more consistent way Alpha Draft

And the others Search API will need updated based on changes to Annotations in the Presentation API 3.0 Authentication API… ?

Discovery Working Group The Discovery Group is focused on developing and Discovery API Intra and Inter-domain discoverability Current focus is how to improve discoverability and harvesting of IIIF materials by organizations with an interest/understanding of IIIF Discovery Working Group Charter - http://iiif.io/community/groups/discovery/charter/#communication-channels

IIIF Discovery API Provide a standard way for Publishing and Harvesting IIIF content on the Web Intra-domain discovery – IIIF Provider to IIIF Provider Inter-domain discovery – Search Engines Site Maps – HTML Resource Sync - XML Activity Streams - RDF

IIIF Discovery API Provide a standard way for Publishing and Harvesting IIIF content on the Web Intra-domain discovery – IIIF Provider to IIIF Provider Inter-domain discovery – Search Engines Site Maps – HTML Resource Sync - XML Activity Streams - RDF

IIIF Discovery API Currently in version 0.1 Discovery API Draft Hopefully will be 1.0 soon-ish Discovery API Draft

Community + Standards: OCLC’s Future

CONTENTdm Community engagement Workshops to help CDM users better understand IIIF and how it works with CONTENTdm Collect feedback on what you want to do with your data in CONTENTdm and see how that maps to IIIF services, tools, features, etc.

IIIF Community engagement Helping develop and improve the IIIF APIs Representative of the data and services needs of the CDM community Help develop community best practices for IIIF Encourage the CDM community to get involved in the Community Groups Or propose your own!

CONTENTdm IIIF Support CONTENTdm will create and maintain IIIF Collection Manifests Descriptions of CONTENTdm Collections Based on the IIIF Presentation API Collections will point to all individual items All Items will point back to the collection

Continued production support & development Evaluate new IIIF APIs and new versions for future CONTENTdm support  Support for Mirador

OCLC Research IIIF Work IIIF R&D OCLC Research contributes to the development of the IIIF Discovery API Providing Use Case Proofs of Concept Actively supporting a prototype of a Discovery API endpoint 8 CDM Users covering 1.8 Million Items

Discovery API Prototype Endpoints can be harvested and the item metadata can be indexed for searching OCLC Research is prototyping what a cross-CDM Collection discovery layer looks like

Broader opportunities No reason we have to focus just on CDM Using the IIIF Standards we could harvest any IIIF resources and build an index for search specialty indexes

So What? Dedicated collaborative effort at OCLC to support IIIF: IIIF Community CONTENTdm IIIF service support CONTENTdm Community understanding of IIIF “Together we make breakthroughs possible”… “, both big and small”
