      using (var kg = new KnowledgeGraph(kg_props))
      {
        //Get the KnowledgeGraph Data Model
        using(var kg_dm = kg.GetDataModel())
        {
          //TODO use KG data model...
        }
      }
    });

        //Get the KnowledgeGraph Data Model
        using (var kg_dm = kg.GetDataModel())
        {

          System.Diagnostics.Debug.WriteLine($"Timestamp: {time_stamp}");
          System.Diagnostics.Debug.WriteLine($"Sref: {sr.Wkid}");
