hi silvain, if you need qualified relationship you have to decompose m:n into two 1:n (have a look at person-role-project) in the testcases.

Is it also possible if you qualified this self reference (add information about relation)? For example if class A have a reference to another instance of class A and this reference has information like reference_name or something like that.

In other words class A can have a reference to another instance of class A or a collection of class As. You may need to make these proxies if the graph is very large and you need to control the hits to the db.
