{
  "tables": [
    {
      "name": "primaryresult",
      "columns": [
        {
          "name": "startdate",
          "type": "string"
        },
        {
          "name": "enddate",
          "type": "string"
        }
      ],
      "rows": [
        [
          "01/01/2014",
          "31/01/2014"
        ],
        [
          "01/02/2014",
          "28/02/2014"
