      vaem:description "QUDT, or the 'Quantity, Unit, Dimension and Types' ontology defines the base classes properties, and restrictions used for modeling physical quantities, units of measure, and their dimensions in various measurement systems. In physics and science, dimensional analysis is a tool to find or check relations among physical quantities by using their dimensions. The dimension of a physical quantity is the combination of the basic physical dimensions (usually mass, length, time, electric charge, and temperature) which describe it; for example, speed has the dimension length / time, and may be measured in meters per second, miles per hour, or other units."^^xsd:string ;
