Andreas, in 2.0

    Relation    = fbl::I_Table
    Record      = fbl::I_Record
    Predicate   = fbl:: Enode_Pred
    
By the way, Andreas, if you want I can set up for you access to our CVS for
2.0 kernel. 

Next, it looks right now as near target I have think about I_Table and
Predicates....and selections from table.

I think after this as layer about can be built layer for relational
operations as you describe. It is good that you have express this so
explicitly.
