As a developer I want the JSON Schema definition of the output in the metadata section of the response.

For instance the service groupsanddomains will present the following:

"metadata": {
   "targetSchema":{
      "type":"object",
      "properties":{
         "metadata":{
            "type":"object",
            "title":"Metadata",
            "description":"Metadata for the 'groupsanddomains' service."
         },
         "data":{
            "type":"array",
            "title":"Data",
            "description":"Data for the 'groupsanddomains' service.",
            "items":{
               "type":"object",
               "title":"Domain",
               "description":"FAOSTAT domain.",
               "properties":{
                  "GroupCode":{
                     "$ref":"#/definitions/code"
                  },
                  "GroupNameE":{
                     "$ref":"#/definitions/label"
                  },
                  "DomainCode":{
                     "$ref":"#/definitions/code"
                  },
                  "DomainNameE":{
                     "$ref":"#/definitions/label"
                  },
                  "Ord":{
                     "$ref":"#/definitions/ord"
                  }
               }
            }
         }
      }
   }
}
