Context and Selectors
Selectors are the AO way to define the context within a document (text, image, audio, video…)
Multiple kinds of selectors can be defined for each kind of document

Text Annotation

Image Annotation

Annotation Types
As it was happening in Annotea, in AO the Annotation can be sub-classed in more specific annotation types:
Annotation

Annotation Curation

Annotation Curation Tokens

Annotation Sets (1)
Are grouping annotation items
Can be useful for grouping annotation items with the same provenance (for example the annotation produced by text mining services)
Can be useful for grouping annotation items with the same topic (for example the annotation regarding life science entities)
Allow to define access restrictions for the grouped annotation

Annotation Sets (2)

Document Annotation (1)
Is a collections of annotation sets – within all those available - that have been combined for a specific purpose – usually for publication - by a particular user/group/content provider
Multiple ‘Document Annotation’ instances can be defined for the same document

Document Annotation (2)

Integration with Annotea and SIOC
