SPARQL Update is very important to this community group. It basically 
means you can perform the following sequences of commands against a 
SPARQL endpoint (subject to endpoint ACLs):

# copy graph <urn:sparql:11:qa:tests:data> to graph <urn:sparql:11:qa:tests2:data>
# move graph <urn:sparql:11:qa:tests:data> to graph <urn:sparql:11:qa:tests3:data>
# Verify using:
# select * from <urn:sparql:11:qa:tests:data> where {?s ?p ?o}
# no records == verified
# select * from <urn:sparql:11:qa:tests3:data> where {?s ?p ?o}
# one or more records == verified.
# Add new records to the empty graph <urn:sparql:11:qa:tests:data> using:
# insert into graph <urn:sparql:11:qa:tests:data> {<#kidehen> owl:sameAs<http://kingsley.idehen.net/dataspace/person/kidehen#this>}
# add data from graph <urn:sparql:11:qa:tests:data> to graph <urn:sparql:11:qa:tests3:data> using:
# add graph <urn:sparql:11:qa:tests:data> to graph <urn:sparql:11:qa:tests3:data>
# select * from <urn:sparql:11:qa:tests3:data> where {?s ?p ?o}
# two or more records == verified.
