UML25 — UML 2 Super/ Classes / issue with Property::isComposite

Open Closed All
  • Key: UML25-625
  • Legacy Issue Number: 7881
  • Status: closed  
  • Source: Simula Research Laboratory ( Dr. Bran Selic)
  • Summary:

    There is a serious inconcistency in the specification with respect to Property::isComposite.

    In the description of Association, it states that "Composition is represented by the isComposite attribute on the part end of the association being set to true".

    But in the discussion of structured classifier parts or the discussion of profile extensions it implies the opposite. isComposite should be true for the end that is owned by the whole.

    This will have a serious impact on interchange (among other things) if different implementations put the "black diamond" on different ends of the composition...
