Incidentally, Leigh’s intention for adding other voacabularies to the FAM2 seems pretty much the same as mine did:

I think for the first iteration I’ll simply throw away properties the FOAF-a-Matic doesn’t understand. Then progressively expand the breadth of FOAF data the tool can process. That way there will be enough new code for a second functioning beta.

But that was when I didn’t think it was possible to dynamically generate the Thinlet UI. I’m now not too sure as to how impossible this would actually be. Elements can certainly be generated at run-time, and added to the main UI – selecting the correct widget to use for the options available would be far harder.
