Annotation > Region > Interval


Definition An annotation over an interval of two-dimensional primary data, either a text or a video or audio stream. An Interval may be defined by pointing directly into primary data (by using start and end offsets) or by linking to one or more other Annotations with the targets property. This annotation type is intended to be an abstract type and typically one of the sub types will be used.

Metadata

Metadata from Region

Property Type Description

Metadata from Annotation

Property Type Description
medium ID The identifier of the medium that the annotation is over. [Required]

Properties

Property Type Description
start Integer The starting offset in the primary data. What unit is used is determined by the *unit* metadata property.
end Integer The ending offset in the primary data. What unit is used is determined by the *unit* metadata property.
targets List of IDs IDs of a sequence of annotations covering the region of primary data referred to by this annotation. Used as an alternative to *start* and *end* to point to component annotations (for example a token sequence) rather than directly into primary data, or to link two or more annotations (for example in a coreference annotation).
