Scales of Measurement are a fundamental property of a Measure describing the allowable mathematical transformations that can be legitimately applied to it.
Attached are some URLs that will give you an overview of Scales of Measurement. Since they therefore determine the statistical methods that can be applied to the Measure, they need to be treated as a first level attribute of a Measure.

It is proposed to introduce an Enumeration to define the possible Scales of Measurement: ordinal, nominal, interval and ratio. Also to add an attribute to Measure, to define its scale.
