[news.eclipse.tools.uml2] Re: Action Semantics support

["James Bruck" <jbruck@xxxxxxxxxx>]

Hi Antonio,

To explain a bit better ...

I can see the ambiguity to the question about "Action Semantics".    I guess
the answer really depends on what was originally intended by the original
question.
The UML metamodel does support actions and can be said to define "Action
Semantics" in that it is a way to specify actions.   In that case,
opensource UML does support "Action Semantics".

However, from what I understand the term "Action Semantics" usually refers
to an OCL type language to bridge the gap between ambiguity in the UML
metamodel and fully specified actions.

The UML specification of Actions has come a long way in the latest version
so I am not certain how much of the original ambiguity as existing in UML1.x
still exists currently.

I hope that clarifies.

- James.
