UMLR — Example for association-like notation for attribute contradicts description.

  • Key: UMLR-624
  • Status: open  
  • Source: Change Vision ( Michael Chonoles)
  • Summary:

    In 9.5.4 page 114, it says
    "In a Classifier, an attribute may also be shown using association notation, where only an aggregation adornment (hollow or filled diamond) may be shown at the tail of the arrow."

    However, in Figure 9.12 on page 116, an example is given with the following problems
    1) No aggregation adornment is shown
    2) A navigation adornment is given
    3) An ownership ball is given.
    4) An association name (role) is given.
    5) Multiplicity is given

    I assume that the attribute this is supposed to illustrated is endName:ClassName.

    Also, it doesn't seem to make sense to use a hollow aggregation adornment, as this would allow an attribute to be shared, which is otherwise not possible.

    Please add a little text to this example, showing
    1) what notation is required
    2) How it is distinguished (if all all) from an actual association end.
    3) What the attribute name is derivable from the diagram
