JTTP: Coherent output formats

JTTP is the default protocol

General JTTP output format:

{
    "status": "success|error",
    "code": "HTTP status code",
    "message": "HTTP status message",
    "data|error": {
        "your data": "data or error field only in case of success or error"
    }
}

Example - GET resource: GET /v1/books/1

{
    "status": "success",
    "code": 200,
    "message": "OK",
    "data": {
        "id": 1,
        "title": "PHP & MySQL Novice to Ninja",
        "_links": {
            "self": {
                "href": "/v1/books/1"
            }
        }
    }
}

Example - GET collection: GET /v1/books

{
    "status": "success",
    "code": 200,
    "message": "OK",
    "data": [
        {
            "id": 1,
            "title": "PHP & MySQL Novice to Ninja",
            "_links": {
                "self": {
                    "href": "/v1/books/1"
                }
            }
        },
        {
            "id": 2,
            "title": "Head First PHP & MySQL",
            "pages": 812,
            "_links": {
                "self": {
                    "href": "/v1/books/2"
                }
            }
        }
    ]
