Logical Model: Precondition2 (CDA Class)

The sdtc:precondition2 extension allows a more flexible set of skip conditions on a set of criteria. Without this extension the skip condition is restricted to all criteria true. The extension allows a choice of the following logical operation extensions sdtc:allTrue, sdtc:allFalse, sdtc:atLeastOneTrue, sdtc:atLeastOneFalse, sdtc:onlyOneFalse, and sdtc:onlyOneTrue to be placed upon the encapsulated criteria or a criterion. The logical operation extensions nest a [0 .. *] sdtc:precondition2 extension allowing for a complex specification of nested skip conditions if needed.

Usage:

• Use this Logical Model Profile: Act (CDA Class), Encounter (CDA Class), Observation (CDA Class), ObservationMedia (CDA Class)... Show 4 more, Organizer (CDA Class), PreconditionBase (CDA Class), Procedure (CDA Class) and RegionOfInterest (CDA Class)
