Dear all, I'm experiencing problems when serialising graphs managed by the latest available version of Opensource Virtuoso. The graph contains many blank nodes and when a take a look at the serialisation produced by dump_one_graph I see triples like:
<> rdf:type owl:Class . <> rdf:type owl:Restriction . Is it possible to dump a graph using another serialisation like RDF/XML in order to overcome this? I don't know if this is a related issue with the strange behaviour I'm experiencing when loading a complex OWL ontology [1] into a "schema" graph used for reasoning. When I do that and query the base graph (using define input:inference the previous schema graph) I get different kinds of exceptions referring to error Tag 0, Tag 248, etc. I'm sending this SPARQL queries to Virtuoso through the Jena connector available at [2] and ARQ 2.8.6. By the way, how can I make it work with virtjdbc4.jar instead of virtjdbc3.jar?
