Hi.
Thank you for your answer and your explanation!
Regarding the UML 1.3 standard, I can now understand my troubles!
I full agree with you. I am reverse-enginering a system using a lot of
recursive relationships and object diagrams (called also instance diagrams?)
are very usefull in that case. I will try to use collaboration diagrams as
a substitute and I do think that object diagrams should be integrated in
ROSE. An object diagram could be seen as a realization a class diagram (that
is an instance) and also could be connected to a sequence diagram (to give a
snapshot of the graph of objects associated with the sequence).
Nevertheless, I would be very interesting in understanding why that kind of
diagram is not in ROSE since some of UML books describe and present it as a
part of the langage...
