Hi Simon,

I find dc:provenance is a quite interesting concept. What do you think? 
Is this covered by OPM to your expertise?

dc:provenance - a statement of any changes in ownership and custody of 
the resource since its creation that are significant for its 
authenticity, integrity, and interpretation.

cheers,

Jun
