+Question:+
Fiware STH: row data API not exposing metadata

+Description:+
I am using Cygnus with Mongo and sth sink to retrieve historical data.

In the current implementation of cygnus mongo sink the attribute metadata is not stored in the data base. So I updated cygnus to be able to store the attribute metadata.
But when I use the STH-comet to retrieve the history, the API appreantly does not support retrieveing the attribute metadata. 

Am I missing some kind of configuration or the API is not supporting the attribute metadata since the response that I am getting from STH-comet is:

    {
  "contextResponses": [
    {
      "contextElement": {
        "attributes": [
          {
            "name": "humidity",
            "values": [
              {
                "recvTime": "2017-03-08T08:06:11.463Z",
                "attrType": "Number",
                "attrValue": "999"
              },
              {
                "recvTime": "2017-03-08T08:10:54.199Z",
                "attrType": "Number",
                "attrValue": "3.06"
              }
            ]
          }
        ],
        "id": "Room1",
        "isPattern": false,
        "type": "Room"
      },
      "statusCode": {
        "code": "200",
        "reasonPhrase": "OK"
      }
    }
  ]
}


In the mongoDB data base I have this content:

{ "_id" : ObjectId("58bfbb7c973c5c22d258cffc"), "recvTime" : ISODate("2017-03-08T08:06:11.463Z"), "attrName" : "humidity", "attrType" : "Number", "attrValue" : "999", "attrMetadata" : [ ] }
{ "_id" : ObjectId("58bfbc93973c5c22d258cffd"), "recvTime" : ISODate("2017-03-08T08:10:54.199Z"), "attrName" : "humidity", "attrType" : "Number", "attrValue" : "3.06", "attrMetadata" : [ { "name" : "unit", "type" : "Text", "value" : "voltage" } ] }


In case the API is not supporting the retrieval of the attribute metadata, can this feature be added?

Thanks & Best regards.
