Overview / Open Energy Ontology / Class - unit

Label: unit

Definition:

A unit of measurement is a generically dependent continuant that represents a standardised quantity value of a quantifiable entity

Editor note:

The OEO developers have different views on the correct classification of a (physical) unit. On one hand, a (physical) unit is often referred to be "a standardized quantity", e.g. in the UO, and thus is interpreted as a quantity itself. On the other hand, a (physical) unit can be seen as a generically dependent reference measure that is not bound to a specific bearer. Together with the numerical value it can describe a quantity value. In the OEO, we have opted for the latter view and therefore implemented (physical) unit as generically dependent continuants.
