Re: [dotNetRDF-Support] Query

Hi Dilshan

I will tell you the answer but I get the impression that it won't really
solve your problem which would appear to be that you don't  know SPARQL very
well?

I would strongly suggest reading a good SPARQL tutorial like SPARQL by
Example [1] or getting a book like Learning SPARQL [2] in order to help you
learn SPARQL properly

For now however you simply need to modify your query like so:

SELECT * WHERE { <http://www.owl-ontologies.com/unnamed.owl#Ferrari> ?p ?o}
