UMLR — AssociationEnd/Attribute redefintion consistency

Open Closed All
  • Key: UMLR-679
  • Status: open  
  • Source: Model Driven Solutions ( Dr. Edward Willink)
  • Summary:

    A Property may be an AssociationEnd (association <> null) or an Attribute (association = null).

    Is it permissible for an AssociationEnd to be redefined as an Attribute and vice-versa?

    "6.4.2 The constraint

    {redefines endA}

    means that the association end to which this constraint is applied redefines the association end endA."

    suggests such a redefinition is wrong.

    "9.9.17.7 Property::isConsistentWith"

    does not exclude such a redefinition..

    Suggest isConsistentWith should require consistency wrt Property::association <> null.
