The EMF wizard from RationalRose model converts package names to lowercase in the generated model.ecore. This respects the naming convention of java packages.
The EMF wizard from UML2 (exported from MagicDraw) leaves the package name case.
Can anyone explains why the EMF wizard from UML2 doesn't work like the one from Rose ?

Hi

Whether names should be converted is a highly subjective topic.

The UML genmodel has a variety of PROCESS options for which I think this
behaviour is one.

Use Generator->Show Annotations to see the top level
http://www.eclipse.org/emf/2002/GenModel/importer/org.eclipse.uml2.uml.ecore.importer
annotations in the main editor pane.

Ed,

I don't think the case conventions in Ecore are highly subjective. Java
has well-defined conventions and EMF follows those so best that
converters produce the appropriate convention just as it's best for a
generator should generate Java with an appropriate convention.

Hi Ed

It's not Ecore that subjective. The question is about UML names.

Ecore has a clear Java-like policy.

UML has its own names.

There is a strong view that UML names should be preserved.

There is an equally strong view that once in the Ecore/Java world, UML
names should be converted.

Regards

Ed Willink

Ed,

Certainly with XML Schema conversion we record the original names from
the schema; they're very important for producing a conforming XML
serialization from the instances. I don't suppose the same concern
arises for UML... Or maybe it does?
