qualityQuantityValue

Source ontology	Industrial Data Ontology
is primitive	false
natural language definition	If x has 'quality quantity value' y, then x is an 'object', and y is a literal value that quantifies a quality of x.
usage note	When introducing shortcut properties as subproperties, annotations should be provided to explain the intended quantity type, any quantification type (e.g., measured, nominal, etc.), and unit of measure.
	This relation is "abstract" (in the object-orientation sense of the word), a "hook": it serves only as a parent for specialised data properties. It serves as a super-property for "shortcut" relations that combine a quality, and a unit of measure into a simple data property.
Example	Mass in kilograms, pressure in barg.
