I'm new at ATL, and I was trying to implement a transformation via ATL.

I've a metamodel A, like this:

Model( List{TI} )
TI (List{AC})
AC (name:String)

and I want to transform A models to a model conforming to a metamodel B.
B:
Model( clas: List{Cla} )
Cla (name)

My problem is that I know
A!Model is transformed to B!Model and B!Model.clas will contain a Cla for each AC in TI.

So I have:

rule Model {
s: A!Model
t: B!Model(
clas <- A!TI->allInstances()
)

but I dont know how is the rule for TI, since it should return a set of Clas.

Someone can explain me, how to do, when there are intermediate objects that are just containers, with no direct transformation?

Thanks in advance.
Rui
