I was wondering what happened to GRAPH in the template.

INSERT { GRAPH <g1> { ?s ?p 45 } }
WHERE { ?s ?p ?o . FILTER (?o < 0) }

DELETE { GRAPH ?g { <s> ?p ?o } }


I am unsure as to which is best at the moment.  I was hoping for 
concrete examples (see telecon) to try to understand which is best.
