8.2.4 Units of Measure

The RESQML-recognized units of measure are listed in the Properties package in the Resqmluom enumeration. Both property and property kind are associated with a UOM. The representative UOM of a property kind is a typical UOM associated with a property kind; it is constrained by the measure class that the property kind is based on. Often, it corresponds with SI units, but it's not required. The UOM of a given property must be consistent with the representative UOM of its property kind.

NOTE: The Energistics UOMs are extensible for property value and property kind. To specify a UOM not in the Energistics UOM standard, specify the property’s UOM as "Euc" (a place holder value). Then use ExtraMetadata, which is a top-level object component, to specify "Uom" as the Name, and the UOM symbol (such as "barns/electron" or "s1/2") as the Value.
