Agenda
• Introduction to IIIF • Image API • Presentation API• Exemplar Software Implementations• Questions/Discussion
![Page 3: IIIF for Index of Christian Art](https://reader035.fdocuments.net/reader035/viewer/2022062420/55d4bde5bb61eb516c8b46f0/html5/thumbnails/3.jpg)
Digital Image Delivery is…
…too hard…too slow
…too expensive…too disjointed
…too ugly
…and we <repositories, software developers, users, funders> suffer because of it.

Distinct Concerns
Find, Use, Analyze, AnnotateWant: Mix & Match, Best of Breed
Scholars
Tool Makers
Repositories
Build useful tools and appsWant: Users &
resources
Host, Preserve (and Enrich) ResourcesWant: Use of Resources, Enriching services, Enriched content

IIIF Scope
![Page 8: IIIF for Index of Christian Art](https://reader035.fdocuments.net/reader035/viewer/2022062420/55d4bde5bb61eb516c8b46f0/html5/thumbnails/8.jpg)
Use Cases…a paleographer who would like to compare scribal hands from manuscripts at two different repositories
…an art & architecture professor who would like to assemble a teaching collection of images from multiple sources
…a humanities scholar who would like to annotate a high resolution image of an historical map (but her preferred annotation tool only is deployed against other sites)
![Page 9: IIIF for Index of Christian Art](https://reader035.fdocuments.net/reader035/viewer/2022062420/55d4bde5bb61eb516c8b46f0/html5/thumbnails/9.jpg)
More Use Cases …a repository manager who would like to drop a newspaper viewer with deep zoom into his site with no customization required
…a national library that would like to host digital surrogates for resources held by smaller institutions (without local IT capabilities), but let them present resources with local branding
…a funder who would like to underwrite the digitization of a new scholarly resource, but does not want to pay for the development of yet another, stand-alone, digital collection web site from scratch
![Page 10: IIIF for Index of Christian Art](https://reader035.fdocuments.net/reader035/viewer/2022062420/55d4bde5bb61eb516c8b46f0/html5/thumbnails/10.jpg)
IIIF Vision
Create a global framework by which image-based resources (images, books, maps, scrolls, manuscripts, musical scores, etc.)
…from any participating institution can be delivered in a standard way
…via any compatible image server…for display, manipulation and
annotation in any application, …to any user on the Web,
…in any combination of elements.

IIIF Objectives
• Define APIs for – Image Delivery– Presentation
• Recruit repositories for API adoption • Catalyze software development– Zoomers, Viewers, Page Turners, Anno tools– Really fast, really slippy image delivery
• Establish an ongoing effort

Audience and Scope
• The Web!• Assumes a curated set of source images• Region, Size, Rotation, Quality, Format• Compression, color management, etc. are out
of scope
![Page 16: IIIF for Index of Christian Art](https://reader035.fdocuments.net/reader035/viewer/2022062420/55d4bde5bb61eb516c8b46f0/html5/thumbnails/16.jpg)
Image API URI Syntax
# Base URI {scheme}://{server}{/prefix}/{identifier}
# Image Request{$BASE}/{region}/{size}/{rotation}/{quality}{.format}
# Image Information (Metadata){$BASE}/info.json

IIIF Presentation API
• Just enough information to drive interoperable image delivery– labels, title, sequence, attribution, etc.
• Implements http://shared-canvas.org
• Relate parts of image-based resources– Images, Text, Annotations, Transcriptions, Sequence /
Structure
• Good URI’s for linking data
• Support for annotation tools & initiatives
• No need to change internal data model or internal data store
