6-1. Overview

6-2. Basic Mechanism

• Image API
  The Image API defines how image data stored on a server are returned in specified formats using URL syntax.
  [Image API implementations] IIPImage Server, Loris, digilib, Djatoka, etc.
• Presentation API
  The Presentation API defines a metadata model describing the structure and properties of single images or image sequences. Open-source image viewers using this metadata and the Image API are under active development.
  [Presentation API viewers] Mirador, Universal Viewer, Diva.js, IIPMooViewer, etc.

6-3. Interoperability

• Mashups
  Presentation API metadata can describe not only a single image but also collections of multiple images, including hierarchical structures.
  Images can be sourced from multiple servers, allowing a single collection to aggregate images held (and published) by multiple institutions.
• Additional information
  Metadata based on the Image and Presentation APIs can include license and rights information.
  The Presentation API also supports annotations with coordinate data. Using a viewer that supports annotations, you can implement features such as displaying transcriptions directly on images.
