Hi Anne,
Fame does not have this support. But, for generation purposes, I think the
upper bounds should be pretty much enough: as long as you have * upper
bound, you should model it with a collection.
Could you give an example of how the lower bounds would change the
generation?

Hi,
I can't see how Fame enable to express that a Property in a metamodel is
mandatory or not. The isMultivalued property of the FM3PropertyDescription
class enables to specify that a property is multivalued or not, but nothing
concerning the character mandatory of the property. Saying that in other
words, it is possible to specify in a metamodel that the upper multiplicity
of a property is '*' but I can't see how to specify the lower multiplicity.
For example considering the metamodel of stateMachine. A State is
contained in one and only one StateMachine, whereas a StateMachine can
contained 0 or several states. A transition has one and only one State as
source and a state can be the source of 0 or several transitions.
Does Fame enable to express this mandatory characteristic?
Expressing such a thing may facilitate some generations. Indeed, when
adding a State, we must specify its container but it is not mandatory to
specify the transitions for which it is a source.
Thank you in advance for your help.
Anne
