UML14 — Use Case Metamodel - UML2 Superstructure issue

  • Key: UML14-411
  • Legacy Issue Number: 6505
  • Status: closed  
  • Source: Daimler AG ( Mario Jeckle)
  • Summary:

    I tried to understand some parts of the Use Case metamodel but get
    stucked ...

    Looking at figure 10-49 (p. 468) of the current (i.d. 3rd rev)
    Superstructure document it is not clear or at least not that obvious
    me how the Actor is related to the Use Case.

    The only possibility seems to be the relationship where the UseCase
    participates taking the role useCase connected to the Classifier. But
    don't think that the Actor should play the role subject ...

    Further, the relationship connecting Actors with UseCases allows the
    placement of Multiplicities but users are not encouraged to use roles.
    Why is this asymmetry introduced? I could imagine situations
    for business models) where roles would perfectly make sense even for
    Actors. This would be the case always when a actor acts on behalf of
    another entity or an actor is to be specialized w.r.t. a specific

    Any ideas?
