Hi Max and all,
-- I am a user of RDF2Go. Could somebody let me know if there is a simple way to serialise QueryResultTable to SPARQL Result XML (http://www.w3.org/TR/rdf-sparql-XMLres/). I have seen there is a java class in Sesame API can do that: http://www.openrdf.org/doc/sesame2/2.3.1/apidocs/org/openrdf/query/resultio/sparqlxml/SPARQLResultsXMLWriter.html

Hi, no, there is not Sparql XML result format support directly in RFD2Go.
For this case, the easiest way to proceed is to call model.getUnderlyingImplementation (or similar) and then type-cast to the specific model that is used (sesame or jena). Then call their API for just this part.
That keeps your code still 98% portable and allows you to do all you need.
We can also always discuss to extend the RDF2Go API,
any proposal is welcome.
Kind Regards,
Max
