A length of time as a quantity, independent of when it occurs — the running time of an event, a gap, a recurrence period. Carries an xsd:duration via gmeow:durationValue. (= time:Duration / time:TemporalDuration, schema:Duration, ISO-TimeML TIMEX3 type=DURATION, TEO Duration.)

Structure

Usage Advice

Use when

• Use for a LENGTH of time as a quantity, independent of when it occurs — a film's running time, a gap, a recurrence period.

Avoid when

• Avoid it for an ANCHORED span (use gmeow:eventInterval / gmeow:TimeInterval, which fixes the event in time); a duration is a length only, with no start or end.

How to use

• Mint a gmeow:Duration carrying an xsd:duration via gmeow:durationValue and attach it to an event with gmeow:hasDuration; the TEO normalized-duration string is a projection target, not a base triple.

Examples

• ex:runtime a gmeow:Duration; gmeow:durationValue "PT2H15M"^^xsd:duration.
