known Usage | The OM ontology provides classes, instances, and properties that represent the different concepts used for defining and using measures and units. It includes, for instance, common units such as the SI units metre (om:metre) and kilogram (om:kilogram), but also units from other systems of units such as the mile (om:mile) or nautical mile (om:nauticalMile-International). For many application areas it includes more specific units and quantities, such as the unit of the Hubble constant: km/s/Mpc om:kilometrePerSecond-TimePerMegaparsec, or the quantity vaselife om:VaseLife. |
