A Quantitative Value is a numerical interval that represents the range of a certain quantitative Product or Service Property in terms of the lower and upper bounds for one particular Product Or Service. It is to be interpreted in combination with the respective Unit Of Measurement. Most quantitative values are intervals even if they are in practice often treated as a single point.
An instance of this class is an actual value for a quantitative property of a product. This instance is usually characterized by a minimal value, a maximal value, and a unit of measurement. This class is a work-around caused by the fact that OWL does only support binary relations, and that datatype ranges cannot be easily handled in OWL.
Example: a weight between 10 and 25 kilogramms, a length between 10 and 15 milimeters.
