making statements about a graph

Hi,

Suppose I had a data set pertaining to a single person, or a 
business, but that person or business has no URI identifier (and 
probably can't be allowed to have one). I imagine I'd use a bnode or 
something in RDF to hang the properties off.

How would I best model the data set so I could hang a property of it 
in turn?
