Kelly,

These questions sounds very UML specific and I don't know how to answer
them. I'll add the UML newsgroup to the "to" list and hope they
understand your question.

Hi Kelly,

I'm not sure what you are trying to do exactly. If you are trying to create
your own UML model, you should not have to work with UML.ecore. When you
say "i couldn't instantiate it" do you mean you could not create an instance
of the UML metamodel?

Have a look at the getting started articles here
http://wiki.eclipse.org/index.php/MDT-UML2 .
The UML project defines primitive type libraries in
org.eclipse.uml2.uml.resources UMLPrimitiveTypes.library.uml. etc.
You can also define your own datatypes and primitive types.

Regards,
-James.

Dear James,

I need to create metamodels wich extend and/or restrict UML metamodel. As
i said in other posts, i couldn't use preexisting UML metamodel, so i
created i own UML metamodel (only core package). Later, i created others
metamodels (A,B,C) and loaded my UML metamodel. For example:
in 'A' metamodel i created 'BusinessElement' metaclass wich extends
'Class' of UML metamodel. Finally, i created a model ('aa') conforms to
'A' metamodel using generated EMF plugins. 'aa' model is input ATL
transformation.

When i create an model conforms to 'A' metamodel, i have to create
Datatype(String, Integer), but i would like preexisting datatypes... in
fact i would like to use preexisting UML metamodel (but i couldn't). what
shall i do?

Thanks in advance.

Hi Kelly,

Did you have a look at : https://bugs.eclipse.org/bugs/show_bug.cgi?id=77413
at the articles "Heavyweight extension" and "Extending UML".
Also, have a look at
http://www.eclipse.org/modeling/mdt/uml2/docs/presentations/ EclipseCon2007_LongTalk_files/frame.html

You should be able to use the existing primitive data types defined by the
UML metamodel in your extended model.
When you say that you couldn't use them, were there errors? or could you not
access them via the editor? or programmatically?
I would need more details of how you are creating your extension. Is this
a middleweight extension?

Regards,

- James.
