Support RDF 1.1 - http://www.w3.org/TR/2014/REC-rdf11-concepts-20140225/
From the "What's new" guide at http://www.w3.org/TR/2014/NOTE-rdf11-new-20140225/
more use of IRI rather than URI, which is a problem for
string literal changes; in particular should Swish have a version/mode that supports 1.0 strings with no data type (e.g. it would not coerce them to xsd:string)? I think not, since it's "complicated" and I never liked the 1.0 set up anyway
RDF datasets can probably be handled as a named graph; can Swish support blank nodes for names?
