yeah thats the idea.
Or is there an easier way to do this in meta data, perhaps Table accepting some kind of Relationship object?
how is that easier ? just so you can define the join condition as part of the Table, and then....mappers are easier to create ? or did you want some way where you didnt have to specify the join condition at all ?
with this kind of thing I have chosen to go with "ok, slightly not default condition, so you have to just be explicit". i think a basic explicit interface is ultimately less hassle than something more automagic/switchy.
