Abstract

The QUDT, or "Quantity, Unit, Dimension and Type" schema defines the base classes properties, and restrictions used for modeling physical quantities, units of measure, and their dimensions in various measurement systems. This overlay graph provides additional properties that affect the display of entities in a user interface, as well as some SHACL rules.
