Laurent,

It's best to ask about UML things on the UML2 newsgroup (I've added it
to the "to" list of the reply) and ask about compare on the EMFT
newsgroup. Be sure to read the UML2 FAQ:

http://wiki.eclipse.org/MDT-UML2-FAQ#What.27s_required_to_lo ad_a_UML_.28.uml.29_resource_from_a_standalone_application.3 F

And use google to find related similar questions:

It's best to ask about UML things on the UML2 newsgroup (I've added it

Hi Ed, Laurent,

The thread entitled "Continuing saga of the standalone app" has a =
complete project attached that demonstrates how to load a model (from a =
post on 7/22/2008).

In addition, have a look at =
http://www.eclipse.org/modeling/mdt/uml2/docs/guides/UML2_2. 0_Migration_G=
uide/guide.html
in the section "Programmatic Migration".

.... some other points...

Magic Draw has some known compatibility issues when it comes to its =
serialized format. For example, lowerValue of MultiplicityElement's =
sometimes is initialzed out with type uml:Integer with a value of '*' =
and sometimes as uml:LiteralInteger. lowerValue should be a =
ValueSpecification and so uml:Integer would be incorrect and '*' should =
only apply to LiteralUnlimitedNatural.

If the migration guides still do not help you, perhaps you could post a =
snippet of the model that demonstrates the isssue.

Cheers,
- James.
