5 5  Both the controller and the client GUI send their data as JSON Objects.
6 6  In JSON every Object is an unordered set of key/value pairs. The values of these pairs can be a JSON Object, a JSON Array or a primitive value (integer, string, boolean or null).
7 7  For more information or a complete grammar see [[http:~~/~~/www.json.org/>>url:http://www.json.org/||shape="rect"]].
