what is properly namespaced JSON response?

explanation.txt

1. I thought namespaced means you need to have the name of the record as the key.
2. If I misunderstood, please feel free to correct me.
3. When you say namespace, do you mean that the namespace is the "data" key?

{
  "data": {
     "Hulk Hogan" : {
      "name": "Hulk Hogan",
      "id": "100002"
     },
     "Mick Foley" : {
      "name": "Mick Foley",
      "id": "100003"
    }
  }
}
