SYSML2 — checkRequirementUsageObjectiveRedefinition is incorrect

  • Key: SYSML2-553
  • Status: open  
  • Source: Model Driven Solutions ( Mr. Ed Seidewitz)
  • Summary:

    In 8.3.20.9 RequirementUsage, the checkRequirementUsageObjectiveRedefinition constraint requires that "A RequirementUsage whose owningFeatureMembership is a ObjectiveMembership must redefine the objectiveRequirement of each CaseDefinition or CaseUsage that is specialized by the owningType of the RequirementUsage." However, the objectiveRequirement property of a CaseDefinition (see 8.3.21.2) or a CaseUsage (see 8.3.21.3) is derived to be only the owned objective of the case. This means that, if a case declares an owned objective, but specializes a case with an inherited objective, then checkRequirementUsageObjectiveRedefinition will actually not be satisfiable.
