please help me

Answer 1

    Graph graph1 = new Graph();

    TripleStore store = new TripleStore();
    Notation3Parser n3parser = new Notation3Parser();

    n3parser.Load(graph1, AppPath + "\\n3\\ontology.n3");

    //Create some Nodes
    graph1.NamespaceMap.AddNamespace("my", UriFactory.Create("http://0.0.0.1/#"));
    IUriNode Person = graph1.CreateUriNode("my:firas");
    IUriNode rdfType = graph1.CreateUriNode("my:name");
    IBlankNode dse = graph1.CreateBlankNode("a");
    ILiteralNode robVesse = graph1.CreateLiteralNode("firas");

    Triple t = new Triple(Person, dse, robVesse);
    graph1.Assert(t);

    IUriNode Person1 = graph1.CreateUriNode("my:firas");
    //ILiteralNode LtrNode = graph1.CreateLiteralNode("a", UriFactory.Create(XmlSpecsHelper.XmlSchemaDataTypeString));
    IUriNode rdfType1 = graph1.CreateUriNode("my:a");
    IUriNode robVesse1 = graph1.CreateUriNode("my:person");
    IGraphLiteralNode dfa = graph1.CreateGraphLiteralNode(graph1);

    Triple t1 = new Triple(Person1, rdfType1, robVesse1);
    graph1.Assert(t1);
    IUriNode Person2 = graph1.CreateUriNode("my:firas");
    IUriNode rdfType2 = graph1.CreateUriNode("my:suffers");
    IUriNode robVesse2 = graph1.CreateUriNode("my:insomnia");
    Triple t2 = new Triple(Person2, rdfType2, robVesse2);
    graph1.Assert(t2);

    //SparqlResultSet resultSet = graph.ExecuteQuery(str2) as SparqlResultSet;

    store.Add(graph1);
    Notation3Writer n3w = new Notation3Writer();
    n3w.Save(graph1, AppPath + "\\n3\\ontology.n3");

Answer 2

    //correction
    String AppPath = HttpContext.Current.Request.PhysicalApplicationPath.ToString();
    Graph graph1 = new Graph();

    TripleStore store = new TripleStore();
    Notation3Parser n3parser = new Notation3Parser();

    n3parser.Load(graph1, AppPath + "\\n3\\ontology.n3");

    //Create some Nodes
    graph1.NamespaceMap.AddNamespace("my", UriFactory.Create("http://0.0.0.1/#"));
    IUriNode Person = graph1.CreateUriNode("my:firas");
    IUriNode rdfType = graph1.CreateUriNode("my:name");
    //IBlankNode dse = graph1.CreateBlankNode("a");
    ILiteralNode robVesse = graph1.CreateLiteralNode("firas");

    Triple t = new Triple(Person, rdfType, robVesse);
    graph1.Assert(t);

    IUriNode Person1 = graph1.CreateUriNode("my:firas");
    //ILiteralNode LtrNode = graph1.CreateLiteralNode("a", UriFactory.Create(XmlSpecsHelper.XmlSchemaDataTypeString));
    IUriNode rdfType1 = graph1.CreateUriNode("my:a");
    IUriNode robVesse1 = graph1.CreateUriNode("my:person");
    IGraphLiteralNode dfa = graph1.CreateGraphLiteralNode(graph1);

    Triple t1 = new Triple(Person1, rdfType1, robVesse1);
    graph1.Assert(t1);
    IUriNode Person2 = graph1.CreateUriNode("my:firas");
    IUriNode rdfType2 = graph1.CreateUriNode("my:suffers");
    IUriNode robVesse2 = graph1.CreateUriNode("my:insomnia");
    Triple t2 = new Triple(Person2, rdfType2, robVesse2);
    graph1.Assert(t2);

    //SparqlResultSet resultSet = graph.ExecuteQuery(str2) as SparqlResultSet;

    store.Add(graph1);
    Notation3Writer n3w = new Notation3Writer();
    n3w.Save(graph1, AppPath + "\\n3\\ontology.n3");
