9 Specifying RDF datasets The text could be clearer about where the default graph comes from. The first paragraph hints at this, but the description is cloudy because of the use of "may". Thus the first sentence says "A SPARQL query may specify the dataset ...". The use of "may" in this sentence evidently refers to the user, who "may" choose to use the FROM clause. Third sentence "The RDF dataset may also be specified in a SPARQL protocol request". Does this mean that it is the user's responsibility to use at least one of these two techniques? What happens if the user uses neither? Is this an error? Or perhaps this would mean the default graph is empty? Or does some implementation-defined default kick in? The precise rules for determining the default graph need to be specified. 9 Specifying RDF datasets There is no statement of the formal semantics of the FROM clauses. Fred
