Yes, I'd agree with that approach too.  What would be /really/ helpful 
for end-users would be if the various historically-aware place 
authorities (SAPO, TGN, Pelagios, PastPlace, ...) all used the /same 
/ontological structure to express statements about places in time.  
Possibly something CIDOC CRM-based?
