Hi everyone, happy new year! We've just hit a question about modelling choices, how to represent percentages. We have a data type DV_PROPORTION, which can be used to represent any proportion such as a fraction or a percentage, and we have the DV_QUANTITY data type which can have % as the unit. In most existing archetypes such as the OBSERVATION.pulse_oximetry archetype, we've used the DV_PROPORTION data type for the percent elements, while for some reason in the draft EVALUATION.alcohol_consumption_summary archetype we've chosen DV_QUANTITY with the unit '%' for the "Strength" element.
We've had a look at the data types documentation (https://specifications.openehr.org/releases/RM/latest/data_types.html), and we can't really find any guidance in the examples there. Is there any guidance about this anywhere else? Does anyone have any opinions about when to use each data type for percentages?
