prov-o example relations

Hi Satya, and PROV-O team,

It would be great for the working group to be able to review the 
proposed encodings of the used/generatedBy relations before Monday's 
call as it would allow those that can't take part on the call to comment 
ahead of it.

Is it possible to have them by Sunday?

I know it's the weekend but it would be really helpful.

Thanks!
Paul
