Possibility to have virtual domain class in Sirius?

[isso84]

Hi,
My question is: is it possible to have a virtual domain class in Sirius?

What I mean is a virtual class that does not exist in the Ecore model, but is instead composed of one or more existing domain classes in Ecore. The goal would be to represent an abstraction of elements.

For example, suppose we have two concrete classes, Cat and Dog, and we want to show them as a single class Animal with its own graphical representation. And of course, internally, it would still contain Cat and Dog, and their attributes and methods could be used.

I’ve tried several approaches, but it seems that Sirius is restricted to mapping one graphic to one Ecore class.

Any ideas?
