FUML — Incorrect generalizations in Kernel

  • Key: FUML-40
  • Legacy Issue Number: 14524
  • Status: closed  
  • Source: Model Driven Solutions ( Mr. Ed Seidewitz)
  • Summary:

    Specification: Semantics of a Foundational Subset for Executable UML Models (ptc/2008-11-03)
    Subclause: 7.2 Kernel

    During work on the fUML submission, the abstract syntax generalization hierarchy was altered to collapse a number of cases of multiple inheritance to single inheritance, in order to allow a mapping to Java for bootstrap execution purposes. Unfortunately, some of these alterations remain in the spec, even though this violates the intended strict subsetting of the full UML Superstructure abstract syntax. The specific cases include:

    • Type -> Namespace -> PackageableElement in Figure 15
    • Namespace -> PackageableElement in Figure 16


    The normative fUML abstract syntax should be updated so its generalization hierarchy is a strict subset of that in the full UML superstructure abstract syntax.
