Technical specifications

IIIF has several stable specifications, each with a distinct purpose and use cases that they serve.

• IIIF Image API - Used to deliver "pixels" to end users
• IIIF Presentation API - "Just enough metadata to drive a viewing experience"
• IIIF Authentication API - An authentication specification and workflow for providing authentication for IIIF images
• IIIF Search API - Used to "search within" IIIF content

Coming soon, IIIF Image and Presentation v3.0

While these have not yet been released in their final form, coming soon is a v3.0 of the Image and Presentation APIs.

• IIIF Image API v3.0 - https://iiif.io/api/image/3.0/
• IIIF Presentation API v3.0 - https://iiif.io/api/presentation/3.0/

IIIF Presentation API v3.0 now supports audio and visual content!

Reflection

Question: How could these APIs benefit machine learning applications?

Question: How can you use machine learning to create data/metadata for your digital content?
