Not sure what I am seeing here.  Is it OK for literal's to be predicates in 
this case?


1) Start up Fuseki-0.2.1 incubating
2) load books.ttl 

3) run this
PREFIX dc: <http://purl.org/dc/elements/1.1/>
INSERT {
   ?s ?c 1 
}
WHERE {
    ?s dc:title  ?c .
}

4) run this (notice literal as predicate)
