Hi Andy and all,
I thought I understood this, but after reading a comment in the open
world tests I am not so sure. So I am posting my question here.
In SPARQL can the pattern "{ ?x :p "001"^^xsd:integer }" match the
literal "1"^^xsd:integer in an RDF store?
Can two literals match in a triple pattern, but return false in a
sameTerm test?
The comment in the file below indicates that an RDF store can either do
value matching or lexical matching. Is it correct?
Thanks,
James

# SPARQL is defined over simple entailment so

# (Some systems may match because they do
# value-based matching in the graph (D-entailment))
# Does not strictly match "1"^xsd:integer
