Specification: Date Time Vocabulary
Title: Quantity Kind is a categorization type
Source: Ed Barkmeyer, NIST, firstname.lastname@example.org (as directed by the FTF)
Section D.3.1 of the Date Time Vocabulary declares the concept 'quantity type' as follows:
Definition: categorization type for ‘quantity’ that characterizes quantities as being mutually comparable
Concept Type: concept type
Figure D.5 shows 'quantity kind' as a <<concept type>>
It appears that the SBVR tag Concept Type should have the value 'categorization type', to match the definition. Moreover, the UML <<concept type>> stereotype does not carry the more important "powertype" semantics that typifies a categorization type. The UML diagram should show 'quantity kind' as a powertype or categorization type. Making it a powertype should also result in a formal UML specification that its instances classify 'quantity'.

Disposition: Resolved — DTV 1.0b2
The FTF agrees that that quantity kind is a categorization type. The powertype aspect is addressed in the UML Profile for SBVR.
Also a CLIF Axiom for ‘quantity kind’ is mis-stated.
