JSON Schema can be used to validate CSON documents. CoffeeScript Object Notation (CSON) is built around the same principles as JSON but based on the CoffeeScript language instead of JavaScript. It has a terser syntax making it easier to write, while maintaining a direct and clear mapping to JSON. This direct similarity makes JSON Schema a natural choice for schema validation.

JSON

[
    {
        "id": 2,
        "name": "An ice sculpture",
        "price": 12.5,
        "tags": [
            "cold",
            "ice"
        ],
        "dimensions": {
            "length": 7,
            "width": 12,
            "height": 9.5
        },
