MARTE — Inconsistencies in GQAM

A number of inconsistencies have been detected in the GQAM subprofile description. The GaScenario stereotype description changes from the domain description section to the UML stereotype description sections (15.2.2.1, 15.3.1 and 15.3.2.12).

The differences are mostly in style of expression rather than substance,
particularly in a property being expressed as an attribute in a diagram, because it
is geometrically awkward to show an association. Attributes and associations are
equivalent properties. There are two differences: (b3) timing is correctly represented in Fig 15.3 by an association
(b4) timing is missing from the stereotype on p 283, and should be added.
(a) GaWorkloadEvent has five properties:
in Fig 15.3 in Fig 15.7 in stereotype p 286
• pattern: attrib attrib attrib
• generator: assoc attrib attrib
• trace: assoc attrib attrib
• timeEvent: assoc assoc attrib
• effect assoc attrib assoc (proposed in resolution of
issue 12538)
The textual stereotype is consistent with the meaning of both diagrams, so no
change is necessary.
(b) The stereotype GaScenario in Figure 15.7 has attributes “cause” and “timing”
which are not correctly represented in Fig 15.3 and in the stereotype on p 283.
(b1) cause is represented in Fig 15.3 by the association inputStream. This should
be changed to cause
(b2) cause is not represented in the stereotype at all, it should be added.
