Hi All,
I need to modify the uml metamodel. That is to add new metaclasses and modify existing ones.
I consider two possibilities: lightweight and middleweight. Both goals may be somehow reached with
the two mentioned ways.

Q1. Do I understand correctly that only the first solution will allow to use all features of uml2
package (I am especially interested in ecore export and import) while the second one will require a
lot of additional programming (for instance importers, exporters and metaclass creation)?

Q2. Is there any comprehensive documentation of uml to ecore transformation (and vice versa)?

Q3. Are manual modifications of UML.ecore file (I understand it to be the uml metamodel description)
the only ways to add new metaclasses?

Thanks in advance,
