composition_of_individual

A <composition_of_individual> is a <relationship> that indicates that the part <possible_individual> is a part of the whole <possible_individual>. A simple composition is indicated, unless a subtype is instantiated too.
<composition_of_individual> is transitive.
NOTE Simple composition means that for example no arrangement of parts is necessarily implied or of concern. Where there is an arrangement of parts, this is indicated by an <arrangement_of_individual>, which, by being a subtype, implies also a simple composition.
EXAMPLE A grain of sand being part of a pile of sand is an example of <composition_of_individual>.
