Hi,
I am sorry the metadata example was not available when I posted my
previous reply - you can take a look at it now:
http://www.jstree.com/reference/_examples/5_others.html (the second
example).

Basically you need this type of structure:
...
        {
                attributes: {id: 1, mdata : "{ type: 'file',
max_depth : 2 }" },
                state: 'closed',
                data: 'Electronics'
        },
...

mdata becomes part of the attributes and its value is a string.

I hope this helps!
Best regards,
Ivan
