Given a triple S, P, O, the reifications that we are most interested in 
would be all ?p and ?o of the form

     <<S P O>> ?p ?o

For example, if a reified triple represents dcterms:created time stamps 
then we want to show them on the forms, or at least make the user aware 
that this information exists and can be queried if desired.
