    {
      //Create a connection properties
      var kg_props =
          new KnowledgeGraphConnectionProperties(new Uri(url));
      using (var kg = new KnowledgeGraph(kg_props))
      {
        //Get the KnowledgeGraph Data Model
        using (var kg_dm = kg.GetDataModel())
        {
          var dict_types = kg_dm.GetRelationshipTypes();

            var name = rel_type.GetName();
            //etc.
            //Get relationship end points
            var end_points = rel_type.GetEndPoints();
            foreach (var end_point in end_points)
