John; The unbound quad warning is just that. It indicates that some triples in the INSERT (or CONSTRUCT) statement were not created because a variable is unbound. It's only a problem if you expect the variable to be bound. If not, CONSTRUCT/INSERT does the right thing - create the triple if the variables are bound and don't if any are not bound.
