Re: [dotNetRDF-Support] skos/rdf

Uldis is quite correct, the SKOS reasoner only works when provided with a
basic SKOS ontology as part of its configuration and when the data being
reasoned over has some SKOS elements.  It looks like there is no relevant
SKOS information in your data (and you didn't show your schema) that can
be used to reason additional triples

You should instead manually convert your data via code or use a SPARQL
update to do this
