Issue 10974: Explanation of Observation notation (uml2-rtf) Source: The MathWorks (Mr. Alan Moore, alan.moore(at)mathworks.co.uk) Nature: Uncategorized Issue Severity: 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 Resolution: Revised Text: Actions taken: April 27, 2007: received issue Discussion: End of Annotations:===== ubject: Explanation of Observation notation Date: Fri, 27 Apr 2007 12:48:14 +0100 X-MS-Has-Attach: X-MS-TNEF-Correlator: Thread-Topic: Explanation of Observation notation Thread-index: AceIwfBHk5ck6h1CQ1ulLYCpQaGMMg== From: "Alan Moore" To: 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.
