I'd need some more details and would point out that Rose itself is way,
way, way past end of life. Such problems are often encountered as a
result of trying to load Rose cross model references.

I think many of these are real problems that indicate that your source
Rose model is not sufficiently specified to generate a valid Ecore model
(by the way, are you importing from Rose to Ecore or to UML?)

These indicate that the classes (Classifier, Feature) somehow define
the same reference property more than once, probably by inheriting
properties of the same name from multiple superclasses.
Java does not support repeated features, so neither does Ecore.
Possibly this is harmless if the features would have the same
semantics, but it may indicate a problem in the source model.

Ecore needs to know what Java type an EDataType in the source model
represents so that it can generate complete and correct code. This is
specified in an Ecore EDataType by setting its instanceClassName
attribute. I don't know how the Rose importer infers EDataTypes from
Rose models, so I can't help any further with this (I don't even know
whether Rose distinguishes DataTypes from Classes).

cf. earlier remarks

The run-time object graphs modelled by Ecore are strictly
tree-structured: an object can have at most one container. The Rose
model has a composite association where the composing end has a
multiplicity greater than one, which implies multiple owners. Ecore
does not support that.

to Christian W. DamusFriend,|
I import the Rose model to Ecore.
My general aim is to extend the CWM (Common Warehouse Metamodel) metamodel , so i import its Rose model (.mdl that i found in the OMG group) to ecore , when i load the model i find the errors displayed before, but i have always the possibility to pass to the next step.
In this case, i generate the .ecore, .genmodel, .edit and .editor and i can also creat instances of that model, but when i validate the .ecore, lot of errors appear and some relations between model instances are missing
As you said, i think that the errors are comming from the Rose model (which dates from 2003 !!)
i hope to find an alternative

Early OMG models predated good modeling tools and so the models often
vary from bad to dreadful.
e.g. UML 2.5 is the first version with fewer than a couple of hundred
OCL itself does not have useable models available from OMG; the QVT 1.2
models are perhaps the best.
Within OMG there has occasionally been discussion about moving from MOF
to Ecore in order to exploit the more coherent tooling.
Today, the implementer of a specification generally should expect to do
significant work with old 'official' models and probably use a certain
amount of common sense to resolve difficulties.
So your Rose problems may well be down to questionable models that were
never exposed to the increasingly strong validation checks that EMF now
