Thanks for your interest. The use case is about, that we need to write a set of archetypes which is usable as datastorage for a HL7 VMR-model in a decision-system. In this model, there is an ObservationResult with type ANY to hold the observation-value. The only query-able solution we can find is to specialize the archetype to common situations. We have, for example an ObservationResult related to pregnancy, in a specialized archetype. Depending on the kind of DataValue, there are other attributes. The customers/users, however are not happy with this. They wonder how it is be done in HL7, of they have the same problem. I don't know, does someone know? What would be a good solution, it would be good also if AQL had a solution to query the type of a datavalue, and than it would be possible to query the value, depending on the type, there would be another attribute to query. Someone has an answer/suggestion to this? regards Bert Verhees
