Hi Tom,

That's also what I thaught, but I'm not sure how to manage provenance
of relationships in a case we export all of them in a single page, eg
[1].
Must/Can we use swp:authority for each statement URI contained in [1]
(see [2]) - or did I missed something with named graphs and RDF/XML ?

Alex.
