Dear All,
How can we add attributes for relationship between two entity? Should we
consider this relationship as a new entity or ... ?
Best,
Ali

I have tried to build a gmf model for the first case in
http://ed-merks.blogspot.com/2008/01/modeling-associations-w ith-ecore.html
(zeroOwnedEnd) but I could not.
What I am trying to do is to have a gmf model with two entity e1 and e2
with a relationship and one attribute for the relationship. I do not want
to have an intermediate entity as relationship on my gmf diagram.

Alireza,

That's a GMF question though and I can't answer it so best to use the
GMF newsgroup for that.
