Result RDF::Query::Solution for RDF/xml about sparql-client HOT 1 CLOSED

The SELECT operator returns a solution set, not an RDF graph, so it can't be serialized to RDF/XML. You may want to do a CONSTRUCT, which can be serialized to RDF/XML.

From the readme:

query = sparql.construct([:s, :p, :o]).where([:s, :p, :o]).limit(10)

query.each_statement do |statement|
  puts statement.inspect
end

You should also be able to do the following:

query.result.to_rdf

Note, there is a mailing list where you can ask questions, rather than raising issues, which might be more appropriate. Send questions or comments to [email protected].
