Hi Li,

I have just had another look at another user which isn't me (school boy error on my behalf ;)

http://sam.tw.rpi.edu/data/face/resource/borisjohnson

And I think I found a bug you in your implementation : 

the above rdf document has a dob of which is set to : -1/16/-001

Which doesn't seem correct to me, perhaps a bug in your code?

I looked at boris's public facebook page and, didn't see his dob, 

http://www.facebook.com/borisjohnson#!/borisjohnson?v=info

but after consulting wikipedia it should be 19th June 1964

Anyways, just another pointer. 

Regards, 

Mischa
