I'm wondering about how to express authoritative participation in a 
entity? How should it be made clear that someone 'belongs' to a 
group? Is it by their own assertion? By the group authority? 

There are some really subtle issues about how people handle 
expression of being part or not part of any number of different 
grouping concepts. Think social circles or cliques, not department 
employee rosters. 

Right now foaf makes no attempt to be authoritative. This is not a 
bad thing. But it does seem like having a way to be more precise is 
going to be important to some folks.

As for indicating group hierarchies and related-ness, there are 
Dublin Core elements and RDF schema constructs that could be 
considered.
