+1 here.  If the relationships are hierarchical / acyclic then YANG would
be a good choice /but/  we also have draft-amante-irs-topology-use-cases-0
on the table, and potentially some related documents incoming;  if these
efforts move forward (ie: modelling inter layer relationships and the
physical plant) we may want to look at other alternatives.

I think this is an interesting discussion to have; it's a bit premature to
settle on a solution given the current uncertainty in the use case set,
*but* it's almost never too early to start experimenting.
