[edit] Explanation for measure
A measure is used to determine the extent or quantity of a concept. It can be a specific extent or quantity of a substance, or a graduated scale by which the dimensions or mass of an object or substance may be determined. A measure in IFD will have a value component and a property dependent unit component.
[edit] Naming of measures
Measures should be named in a consistent way to help users to select the right measure for a given property. As most measures only will have one unit the unit will often be a part of the name of the measure. E.g. "positive length measure in millimeter" and "positive length measure in meter". For a class type of measure the names will often be a group name for a given collection of values e.g. "fire ratings", "shape types"
