The main concept of custom forms is that the values submitted by the HTTP request will be substituted into placeholders in RDF N3 strings.  These strings are then parsed to Jena RDF Model objects and that RDF is added to the system.  For the modification of an existing value, a second set of strings is created and parsed which become the RDF statements to remove for the edit.  This substitution is why the editing system is frequently called “N3 Editing”.  In practice, the N3 strings use only the turtle subset of the N3 syntax.
