[modeling-pmc] Waynes question about how a UML2 Profile looks like
|
Hi, Wayne.
> I'm more curious about the second part of my question. What does a
UML2 Profile look like? Is it just an ecore file, or is there more to it?
A UML2 Profile is first of all an instance of the UML2-metamodel. The
UML2-metamodel can be considered a model written in ECore to simplify
the situation. Thus one answer to your question is that an UML2 profile
manifests as an UML2 model, using the UML2 constructs to define profiles.
However, these profile constructs define additional attributes,
references, inheritance for existing UML2 constructs. Thus the idea is
natural, to do this definitions not as instances of the UML2 profile
constructs, but as ECore models, whose classes extend the classes of the
UML2 metamodel.
In the Eclipse work on UML2, as far as I can guess, I assume, that the
profiles are defined and stored as ECore models, but if we would store
them to correct XMI of the UML2 metamodel, I assume they would not be
ECore models, but UML2 models.
Kenn: please correct me if I told something that is fundamentally wrong.
Regards, Philipp
