I think DV_QUANTITY is the option here. Someone could argue that % is not a proper unit, but it is, both in UCUM and SNOMED CT.
DV_PROPORTION should be only used when you want to maintain the numerator and denominator explicitly separated, as a fraction, which should not be the case with percentages. But it is true that the definition of the type attribute in the specification is a bit misleading: "Indicates semantic type of proportion, including percent, unitary etc." El jue., 3 ene. 2019 a las 7:59, Bakke, Silje Ljosland (< silje.ljosland.ba...@nasjonalikt.no>) escribió: > Hi everyone, happy new year! > > > > We’ve just hit a question about modelling choices, how to represent > percentages.
