Metadata

Metadata from Region

Property	Type	Description
timeUnit	String	Specifies which unit of time the measurement is based. Can be *seconds* or *milliseconds*, or in case of annotations on a VideoDocument, *frames*.

Metadata from Annotation

Property	Type	Description
document	ID	The identifier of the document that the annotation is over. This has to be defined either at the metadata level, in which case it has scope over all annotations of the same type in a view, or at the instance level, in which it has scope over just the single annotation.

Properties

Property	Type	Description
title	String	Title of the chapter

Properties from TimeFrame

Property	Type	Description
frameType	String	The type of TimeFrame. Possible values include, but are not limited to, bars, tones, bars-and-tones, speech, noise, music, slate, chyron, lower-third, credits, and other.

Properties from Interval

Property	Type	Description
start	Integer	The starting offset in the primary data. This point is inclusive. For time intervals, the unit is determined by the *timeUnit* metadata key. For text intervals, the unit is Unicode code point.
end	Integer	The ending offset in the primary data. This point is exclusive. For time intervals, the unit is determined by the *timeUnit* metadata key. For text intervals, the unit is Unicode code point.
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).

Properties from Annotation

Property	Type	Description
document	ID	The identifier of the document that the annotation is over.

Properties from Thing

Property	Type	Description
id	ID	A unique identifier for the annotation or document. Uniqueness is relative to the view the annotation is in or the list of documents at the top level of a MMIF file. [Required]
