Usage:

public class Entity
{
    [Subject(Prefix = @"http://d/data/")]
    public int Id { get; set; }
    [Object(Predicate = @"http://d/ont/name")]
    public string Name { get; set; }
    [Object(Predicate = @"http://d/ont/priority")]
    public int Priority { get; set; }
    [Object(Predicate = @"http://d/ont/category")]
    public ulong Category { get; set; }
}

public class HelloWorld
{
    public static void Main(String[] args)
    {
        IGraph graph = new Graph();
        var generator = new TripleGenerator(new LiteralNodeAdapter(graph));
        var entities = Enumerable.Range(0, 5)
            .Select(ii => new Entity { Id = ii, Category = 52435, Name = string.Format("Entity{0}Name", ii), Priority = ii });
        
        List<Triple> triples = entities.SelectMany(generator.GenerateTriples).ToList();
        graph.Assert(triples);

        var store = new TripleStore();
        store.Add(graph);

        string query = File.ReadAllText("query.txt");
        var executeQuery = graph.ExecuteQuery(query);

    }
}
