Name: 
E18 Physical Thing
Description: 

P8 took place on or within

Scope Note: 

This property describes the location of an instance of E4 Period with respect to an E19 Physical Object.
P8 took place on or within (witnessed) is a shortcut of the more fully developed path from E4 Period through P7 took place at, E53 Place, P156 occupies (is occupied by) to E18 Physical Thing.

E92 Spacetime Volume

Belongs to versions: 
Scope Note: 

This class comprises 4 dimensional point sets (volumes) in physical spacetime regardless its true geometric form. They may derive their identity from being the extent of a material phenomenon or from being the interpretation of an expression defining an extent in spacetime.

P157 is at rest relative to

Scope Note: 

This property associates an instance of E53 Place with the instance of E18 Physical Thing that determines a reference space for this instance of E53 Place by being at rest with respect to this reference space. The relative stability of form of an E18 Physical Thing defines its default reference space.

P156 occupies

Scope Note: 
This property describes the largest volume in space that an instance of E18 Physical Thing has occupied at any time during its existence, with respect to the reference space relative to itself. This allows you to describe the thing itself as a place that may contain other things, such as a box that may contain coins.
