IdCoordinate
IdCoordinate(value=None, unit=None, timeline_id=None, /, **data)A Coordinate that carries the ID of the timeline it belongs to.
Extends Coordinate with a timeline_id field, providing the most specific form of coordinate specification. Operator results inherit the timeline_id (IdCoordinate + Duration → IdCoordinate; IdCoordinate - IdCoordinate → IdDuration when the ids match).
