This extension defines a structure type, LV2_Time_Position, which describes a tempo and position along a timeline. This can be used as an event payload by the host to notify plugins about the current tempo and position.

""" . time:Position a rdfs:Class ; rdfs:label "LV2 time position" ; lv2:documentation """ Type for an LV2_Time_Position struct. This can be mapped to an integer and used as the type field of an event to indicate that the event payload is an LV2_Time_Positon struct. Plugins can indicate that a port supports time information using the ev:supports predicate, e.g.:
	 lv2:port [
		a ev:EventPort ;
		ev:supports time:Position
	]
