Issue

Need to be able to convey more information about the nature of the relationships between Clinical Statements

Recommendation

Add the following attributes to ActChoice.sourceOf1 and ActChoice.sourceOf2/targetOf:

  • inversionInd - cardinality [1..1], conformance Mandatory and default of “false”
  • negationInd - cardinality [1..1], conformance Mandatory and default of “false”
  • seperatableInd - cardinality [1..1], conformance Mandatory and default of “true”

Rationale

All of these attributes are used by NPfIT

  • inversionInd allows the semantic of the relationship to be reversed without changing the clinical statement that is the source act and hence the supplier of the context to the relationship
  • negationInd allows the semantic of the relationship to be negated (does NOT have Cause)
  • seperatableInd allows the sender to state that the source act should not be interpreted without referring to the target act.
