E18 Physical Thing

This property associates an instance of E18 Physical Thing with the instance of E92 Spacetime Volume that constitutes the complete trajectory of its geometric extent through spacetime for the whole time of the existence of the instance of E18 Physical Thing.

This property associates an instance of E93 Presence with the instance of E18 Physical Thing of which it represents a temporal restriction (i.e.: a time-slice) of the thing’s trajectory through spacetime. In other words, it describes where the instance of E18 Physical Thing was or moved around within a given time-span.
