We will continue to run into such problems if we attempt to create all 
of the schemas through hierarchies. It might be useful to think of 
"free-floating facets"[1] for those properties that may be usable in a 
number of different circumstances, like locations, addresses, hours, 
owner, time (dates of existence, creation), etc. Either that, or a whole 
bunch of properties need to be defined at the Thing level. And in the 
spirit of linked data, shouldn't it be possible to link any two 
organizations without one being subordinate to the other?

I'm not sure that the convenience of inheritance out-weighs the 
inconvenience of trying to fit everything into particular hierarchical 
levels.
