temporal_whole_part

A <temporal_whole_part> is a <composition_of_individual> that indicates that one <possible_individual> is a temporal part of another <possible_individual>. The spatial extent of the temporal part is that of the temporal whole for the period of the existence of the temporal part.
Relationships that apply to the whole <possible_individual> also apply to the temporal parts of the <possible_individual>, except when the relationships relate to the temporal nature of the whole. So if a <possible_individual> is connected so are all its temporal parts, but being a <whole_life_individual> is not inherited by its temporal parts.
NOTE Since <temporal_whole_part> is transitive (inherited from its supertype) a hierarchy of temporal parts is possible, with a <whole_life_individual> at the top.
EXAMPLE 1 The relation that indicates that an operating period of a pump is a temporal part of the pump can be represented by an instance of <temporal_whole_part>.
EXAMPLE 2 The relationship that indicates that the time period known as March 1999 is part of the period known as 1st Quarter 1999 can be represented by an instance of <temporal_whole_part>.
