## IWC + JSON Example
Here, I will give a short overview on how to use the IwcJson Framework in Role-SDK widgets.
First you have to include the following libraries in your widget file:
```
<script src="http://open-app.googlecode.com/files/openapp.js"></script>
<script src="http://dbis.rwth-aachen.de/gadgets/iwc/lib/iwc.js"></script>
<script src="http://dbis.rwth-aachen.de/~jahns/role-widgets/widgetbundles/libraries/DUIClient.js"></script>
<script src="../../build/browser/Frameworks/JsonFramework.min.js"></script>
<script src="../../build/browser/Connectors/IwcConnector.min.js"></script>
<script src="./index.js"></script>
```
A working widget implementation is [IwcJson.xml](./IwcJson.xml) and the js-file is [index.js](./index.js)


```js
function init(){
    Y.createIwcConnector(function(Connector, user_id){
```


You don't have to use the proposed user_id.


```js
      // console.log("me is number 1");
      // yatta = new JsonYatta(1, Connector);
```


Though, it is recommended to use the user_id


```js
      yatta = new Y.JsonYatta(user_id, Connector);


    })
}
window.onload = init
```
