Issue 7304: Notation sections for TimeObservation and DurationObservation (uml2-rtf) Source: Missouri University of Science and Technology (Dr. Thomas Weigert, weigert(at)mst.edu) Nature: Clarification Severity: Minor Summary: The Notation sections for TimeObservation and DurationObservation seem inadequate: 1. The syntax for TimeObservation only allows "now" as a TimeExpression, but indicates in the previous sentence that more complex expressions are possible. 2. The syntax for DurationObservation includes the unexplained non-terminal symbol "duration". 3. In the example, figure 321, there are no associations to named elements shown. I assume that these refer to the begin and end of the arrow, but that is not indicated. Resolution: This issue has already been considered by prior RTFs and deemed out of scope, per the following discussion previously recorded for this issue: A proper resolution of this issue depends on changes in progress with respect to the action and activity model. In addition, a more encompassing improvement of the "simple time model" and related concepts is required. Thus, the resolution of this issue is best considered to be strategic.
