Issue 14895: Remove the TimedObservation stereotype (marte-rtf) Source: THALES (Mr. Sebastien Demathieu, sebastien.demathieu(at)thalesgroup.com) Nature: Clarification Severity: Minor Summary: TimedObservation is an abstract stereotype that extends TimedElement without adding new features. It is sublassed by the concrete TimedDurationObservation and TimedInstantObservation. Given that it cannot be directly used, and for the sake of smplicity, removing the stereotype may be considered Resolution: Stereotype TimedObservation was created for consistency with the UML Specification and considering that TimeExpression would refer to TimedObservation directly without deciding on the actual specialization. The stereotype can be removed with no harm. TimeExpression will refer to (untimed) Observation instead. Even though the semantics is weakened, there is no actual impact since the association between TimeExpression and Observation is not actually serialized by any tool. Though, it should be noted that TimedObservation cannot be removed from the Domain View since it is actually used by DurationPredicate and TimePredicate.

Though, you shoud note that this will introduce an asymmetry between the profile and the domain view since we cannot remove the TimedObservation class from the domain view. TimedObservation is used by TimePredicate and DurationPredicate. This is completely in-line the simple time chapter of UML. I have prepared a resolution (available on the wiki), if you wish to continue on this path. Apparently, it is not possible to upload any visio file on this wiki as it was before ? Anyone has any idea on whether we may be able to change the authorizations.

I expect this resolution refers to chapter 9 so I have no objection. However the stereotype in chpater 15 is as far as I can see required for analysis.
