Hi,

I'm a new in EMF, so I need some helps.
I would like to implement a function that if an attribute of a child model will change, an attribute of a corresponding parent will automatically be changed.
How can I implement this?
Could someone help me?

Thanks,
Eunjung Park

Perhaps the parent's attribute can be marked transient, volatile,
derived, and you can implement the logic to compute it in the
implementation class of the parent.
