UML14 — "Inheritance" connection used is a generalization relationship

  • Key: UML14-859
  • Legacy Issue Number: 1390
  • Status: closed

  • Summary:

    Summary: 2. In the same vein, it is clear that the "inheritance" connection used
    in all parts of the metamodel is in
    fact a generalization relationship. I believe this to be the best choice.
    However, I would ask whether ALL of the generalization relationships in the
    metamodel really do fulfil the criterion of generalization i.e. we can
    say yes to the question "is the subclass A KIND OF the superclass?".
    My biggest query here, which I have asked many times, is "Is a Generalizable
    Element a kind of Namespace?" as shown in Figure 6 of semantics document.
    Grady"s answer to me was "the simple reason is that superclasses form
    a namespace". Forming a namespace sounds to me like aggregation or
    membership and not generalization.
