Mapping arbitrary JSON to XDI

In order to be able to map non-XDI data sources such as Facebook, Google Calendar, etc. to XDI, I am thinking it would be useful to have a generic JSON->XDI mapping ability, because that's the format that most of these APIs are based on.

So I played with this a bit, you can go to

http://xdi2.projectdanube.org/XDIConverter

Select "RAW JSON" as the input format, and try sample 5 or sample 6 or any other JSON format.
