data value used for representing a quantity expressing the result of a measuring


This is a concrete item and can be implemented directly

Term: physical quantity value; 
Plural: physical quantity values; 


NOTE 1 The general pattern for a measurement is value unit of Thing. In this scheme, the PHYSICAL_QUANTITY represents the value and the unit, and the Thing is described by some coded concept that is linked to the PHYSICAL_QUANTITY by the context of use. This maps obviously to some measurements, such as subject of care Body Temperature of 37 Celsius, and 250 mg/day of Salicylate.

NOTE 2 This DATA_VALUE specialization is equivalent to ISO 21090:2011 PQ data type. The translation and coding rationale attributes have been removed.
