qudt:organizedUnder

Relates a quantity kind to a broader quantity kind for the purpose of organization and unit applicability only — it does not assert commensurability. A sub-property of skos:broader (so it contributes to the concept hierarchy), but unlike qudt:specializationOf it makes no commensurability claim: qudt:organizedUnder groups quantity kinds that share a dimension but are not interchangeable — principally the dimensionless quantity kinds, which are all organised under quantitykind:Dimensionless / quantitykind:DimensionlessRatio without being commensurable with one another. qudt:organizedUnder still contributes to the concept hierarchy (via skos:broader), and the build still validates that it only links quantity kinds of the same dimension, but the applicable-unit computation traverses only qudt:specializationOf — an organizational grouping confers no units on its members. The commensurability test likewise traverses qudt:specializationOf and qudt:exactMatch (never qudt:organizedUnder).
