TEI element timeline (timeline)

<timeline>

<timeline> (timeline) provides a set of ordered points in time which can be linked to elements of a spoken text to create a temporal alignment of that text. 16.5.2 Placing Synchronous Events in Time

Module

linking — 16 Linking, Segmentation, and Alignment

In addition to global attributes

origin

designates the origin of the timeline, i.e. the time at which it begins.

Status	Recommended when applicable
Datatype	<rng:ref name="data.pointer"/> data.pointer
Values	if suppplied, must point either to one of the when elements in its content, or to another timeline element.
Note	If this attribute is not supplied, the implication is that the time of origin is not known.

unit

specifies the unit of time corresponding to the interval value of the timeline or of its constituent points in time.

Status	Recommended when applicable
Datatype	<rng:ref name="data.enumerated"/> data.enumerated
Suggested values include:	d (days) h (hours) min (minutes) s (seconds) ms (milliseconds)

interval

specifies the numeric portion of a time interval

Status	Optional
Datatype	<rng:choice> <rng:data type="float"> <rng:param name="minExclusive">0</rng:param> </rng:data> <rng:value>regular</rng:value> <rng:value>irregular</rng:value> </rng:choice> xsd:float { minExclusive = "0" } \| "regular" \| "irregular"
Values	a positive number, or one of the two special values irregular or regular.
Note	The value irregular indicates uncertainty about all the intervals in the timeline; the value regular indicates that all the intervals are evenly spaced, but the size of the intervals is not known; numeric values indicate evenly spaced values of the size specified. If individual points in time in the timeline are given different values for the interval attribute, those values locally override the value given in the timeline.
