This property is the super property for all pure datatype properties that can be used to describe a product and services instance, or via the instances placeholders, of a set of instances of mass-produced commodities. In products and services ontologies, only such properties that are no quantitative properties and that have no predefined Qualitative Value instances are subproperties of this property. In practice, this refers to a few integer properties for which the integer value represents qualitative aspects, for string datatypes (as long as no predefined values exist), for boolean datatype properties, and for dates and times.
