UML22 — Explanation of Observation notation

  • Key: UML22-319
  • Legacy Issue Number: 10974

  • Summary:

    UML2 Superstructure 2.1.1:Interactions

    In Fig 14.26 there are various time annotations shown which relate to the Simple Time package.

    The notation sections for TimeObservation and DurationObservation read thus:

    TimeObservation: “A time observation is often denoted by a straight line attached to a model element. The observation is given a name that is shown close to the unattached end of the line.”

    DurationObservation: “A duration observation is often denoted by a straight line attached to a model element. The observation is given a name that is shown close to the unattached end of the line.”

    However the notations in Figure 14.26 look like this:

    TimeObservation: “t=now”

    DurationObservation: “d=duration”

    I don’t see how the example notation is consistent with the notation descriptions
