If the data set is:
@prefix dc: <http://purl.org/dc/elements/1.1/> .
@prefix : <http://example.org/book/> .
@prefix ns: <http://example.org/ns#> .
:book1 dc:title "SPARQL Tutorial" .
:book2 dc:title "The Semantic Web" .
How do I check that the triple :book1 dc:title "SPARQL Tutorial" . exists?
I can do SELECT ?book where {?book dc:title "SPARQL Tutorial"} but then I have to do post processing to determine if ‘book1’ was retrieved!
