JSONAPI boolean attributes

Question

When you work with JSONAPI, how you handle the boolean attributes?

For example:

{
    "type": "motors",
    "id": "1",
    "attributes": {
      "name": "V8",
      "working": "true"
    }
}

or

{
    "type": "motors",
    "id": "1",
    "attributes": {
      "name": "V8",
      "working": "1"
    }
}

Also, I think this is better solution, but don't work with the official specification:

{
    "type": "motors",
    "id": "1",
    "attributes": {
      "name": "V8",
      "working": true
    }
}

Answer 1

The first two examples represent strings and the last example represents a boolean value on JSON (http://www.json.org/)

From the spec:

A value can be a string in double quotes, or a number, or true or false or null, or an object or an array. These structures can be nested.`

If you really want a boolean then use the last example.

JSON:API do not say anything about it because, the specification itself is on top of JSON (inherit all the JSON specification)
