However take care that you are implicitly restricting your
relationships to be binary and directed (from/to)
What if I want a "sibling" relationship?
Sorry Nicolas but I don't follow you. All the relations in Moose are binary: any relation is just among two entities. If I have a one to many relation than I will have multiple relation objects with the same sender and different receivers. Also the lift relation it is not necessarily directed. It is the rationale that makes it directed or not. From and to don't have to mean that the relation goes from the from part and goes to the to part. An attribute that specify if the lift relation is directed or not could be useful to distinguish the case.
It might be implemented in a way that contradict your hypotheses.
The roles might have different names than to/from and it could be
interesting (or not) to take this into account just as you have
"lift: aSelector"
This could mean that instead of returning a collection of
FAMIXLiftedAssociation, you would return a LiftedResult that would
contain a collection of "normal relationships" (whatever they are).
quite impossible to return normal relations since Lift infers and returns relations that do not exist.
The rest of your email about helper methods to return directly the models could make sense in some cases.
Finally, you always give example of queries on moosegroups, did you
exclude queries on single MooseEntity?
A query to a moosegroup of one entity is it not the same?
