If your json is more than a few hundred characters then it may be more appropriate to store it in a [`slicer.vtkMRMLTextNode`](http://apidocs.slicer.org/master/classvtkMRMLTextNode.html):

- You have the option to save the text in a separate file (so that you can view/edit more easily in external software).
- There is a separate `TextModifiedEvent` for indicating text content modifications
- “Texts” module has a small text editor
- You can show/edit the content of the text node in your module using `slicer.qMRMLTextWidget`

You can keep using the scripted module node for other parameters and add a node reference to the text node to store the json text.
