Hi, Lorenzo,

Do you mean, something like UML association-end qualifiers?  Ecore doesn't
support that directly.

However, you can define a containment reference of some EObject type
extending EMap.Entry<K, V>.  In this case, if the value is an EReference, I
think you should end up with an EMap<K, V> property that does what you
need, albeit with the overhead of an EObject for each entry.

HTH,

Christian
