[dotNetRDF-Support] dotNetRDF how to get the value from a INode

[Yuqian (M. L. <yl...@au...>]

Hi dotNetRDF Team,



I am using dotNetRDF library to process my ontology in RDF/XML format.



Following the tutorials on your website, I can easily get a triple from my
graph and further get the INode I am interested in. Then I would like to
retrieve the actual value from the resultant INode no matter it is actually
a UriNode or a LiteralNode. So I was wondering if there is some method in
dotNetRDF that I can use to extract the value from INode?



Below is the code:

            IUriNode rdfType = g.CreateUriNode("rdf:type");

            IUriNode projectType = g.CreateUriNode("ms:Project");

            IEnumerable<Triple> ts =
g.GetTriplesWithPredicateObject(rdfType, projectType);

            foreach (var triple in ts)

            {
*                //UriNode is in the format of [PrefixNamespaceURI]value.*

*                //LiteralNode is in the format of
value^^[URIoftheBuiltinDataType]*

                INode subject = triple.Subject;

*                //Here I need some method to extract the value only*

*                ……………………………………*

            }



It would be much appreciated if you could provide some information on this.



I am looking forward to hearing from you.



Best regards,



Michael
