UML14 — UML 2 Super / Activities / subsetting two properties

Open Closed All
  • Key: UML14-458
  • Legacy Issue Number: 6680
  • Status: closed  
  • Source: Simula Research Laboratory ( Dr. Bran Selic)
  • Summary:

    Activity::structuredNode subsets two properties, Activity::node and Actvity::group. This is among the few, if not the only, cases in the metamodel where a containment property subsets two superset containment properties. What is the semantic intent of this constraint? Should Activity::structuredNode be derived from the set of structured activity nodes in Activity::node and Actvity::group (StructuredActivityNode is both a group and a node)?
