Hi Antonio
Yes, I'm afraid it's confusing, because there have multiple attempts at
integrating OCL validation. The early ones didn't work well. The new
approach useing validation/setting/invocation delegates is much better
and simpler. See http://wiki.eclipse.org/MDT/OCLinEcore for an editor
and the underlying representation.
There are discussions on mdt-papyrus.dev and
https://bugs.eclipse.org/bugs/show_bug.cgi?id=322933 about integrating
the OCL editing into Papyrus so that constraints are sensibly editable,
but that probably needs you to wait for Indigo.
MDT/OCL doesn't inherently support profiles, since I think UML2 does it
automatically. However the support for execution of OCL embedded in UML
is missing and the IUML to ECore conversion of OCL embedded in UML
doesn't provide OCL embedded in Ecore as required by validation delegates.
Sorry, this will be very difficult till the pieces are pulled together
in Indigo.
Regards
Ed Willink
