Hello!
I am new to Atl. My problem is that I have 2 classes and 2 relations between them.
Class A->Class B (relation AB, multiplicity 1)
Class A->ClassB(relation AB2, multiplicity 2)

I need to trnasform it to:
Class A->ClassAB->ClassB(multiplicity between ClassAB and Class A equals 1)
ClassA->ClassAB2->ClassB(multiplicity between ClassAB2 and ClassA equals 2)

How it is possible to implement in ATL?
Thanks for any help!

You may use a collect on the relation (which is a collection of Bs) and
use a called rule to generate corresponding class AB2
( http://wiki.eclipse.org/ATL/User_Guide_-_The_ATL_Language#Ca lled_Rules).
