Since nobody answered so far, I would try to. PMML has been discussed
and agreed to be a good choice for model exchange format.  The main
issue currently is limited (read only and not for all type of models)
Weka support for PMML models.   With some efforts this might be
resolved, what is more challenging is how to make use of PMML for
specific SAR and (Q)SAR models, for example those based on structural
alerts. In particular it is not clear to me how to describe Toxtree in
PMML in a generic way and I am curious if Christoph has a solution for
the lazar system.
