Agenda
IIIF represents an evolution in exchange standards, establishing a uniform way to interact with resources.
With IIIF, images, objects, and collections become significantly more reusable.
APIs! Standardized Application Programming Interfaces makes IIIF so powerful. URIs usable for humans and machines.
What is IIIF?

}Presentation API
aka manifests or prezi
Canvas
- Few required fields
- Id
- Type
- Label
- List of canvases
- Metadata is flexible, but simple
- label (keywords) and value (spade)
Manifest – minimum
Most important to remember, made for humans using IIIF viewers, not for complex metadata
- Attribution to owner
- Define one or more structures, similar to a table of contents
- Provide links to additional resources related to the object
- Integrate other services, such as authorization
Manifest – additional ... stuff

We will look at manifests and collections in the IIIF Manifest editor, Theseus viewer and Mirador
Lets first get some urls from https://api-ub.vercel.app/spec (deprecated, will move to https://api.ub.uib.no/reference)
