[dotNetRDF-Support] NamespaceMap on parsetime

[Jens P. <jen...@gm...>]

Hi

I am doing the folowing: 

http://pastebin.com/rfTC0fZu

/* 
* Getting an error from ParseFromString, saying:
* The Namespace URI for the given Prefix 'foaf' is not known by the in-scope NamespaceMapper
* 
* My question how can i add a Namespace before the parsing?
* I don't like the idea of manualy concatenating a lot of prefix strings to build my queries. 
*
*/ 

ISparqlQueryProcessor processor = new RemoteQueryProcessor(new SparqlRemoteEndpoint(new Uri("http://localhost:11025/sparql/query")));
SparqlQueryParser sparqlparser = new SparqlQueryParser();
SparqlQuery query = sparqlparser.ParseFromString("SELECT ?image WHERE {?image rdf:type foaf:Image}");
query.NamespaceMap.AddNamespace("foaf", new Uri("http://xmlns.com/foaf/0.1/"));
Object results = processor.ProcessQuery(query);

So is there a way to add a namespace to the parser?

Thanks
