This is a beta version of migrating these workshop materials to a new platform. If you run into issues please file an issue or click on the edit link above and submit a pull request. You can use the previous version of the workshop materials as a fallback.

Annotation

We’ve seen various annotations throughout the workshop already. Images are applied to canvases via annotation. Content search results are expressed as annotations.

Here we’re going to look at annotations more in depth and talk about other uses of annotations.

Readers make marks in books. You bookmark pages in your browser. You quote a passage of text and comment on it. IIIF provides the platform for allowing for all different kinds of scholarly annotation.

Annotations can be useful for:

  • Research
  • Teaching
  • Machines
  • Crowdsourcing
  • Conservation

An annotation target is a URI pointing in whole or in part (fragment) to a resources like:

  • web pages
  • audio video
  • images
  • IIIF canvases

Annotation bodies, the content of the comment/annotation, can be:

  • text
  • images
  • audio
  • video
  • URIs

Annotations are created for different reasons like:

  • painting
  • commenting
  • bookmarking

Creating Annotations

Open Mirador and create some annotations over top of an image.

  • How are annotations displayed?
  • What different types of annotations can you create?
  • Why might you use some of the variations within the annotation tools available in Mirador?

Examples

Take a look at some of the examples of how the same annotations allow for different interactions with the Holbein painting: http://storiiies.cogapp.com/

Here’s a video showing annotation using Mirador which is stored in the SimpleAnnotationServer and then presented as a search inside service to the Universal Viewer:

Questions

What kinds of data do you have for annotations? How could you get those into annotations?

Web Annotation

While IIIF currently uses Open Annotation, the specifications will be moving to Web Annotation. The Web Annotation Data Model includes lots of examples with use cases and JSON that make it an easy to read specification.
