hi -
i like this example of adding a new superclass A   of B and C which is 
made by dropping a restriction on both B and C.
the example below with bookings sounds good.

if we want one for planes, we could look at the top level plane class.  
(I am not sure that i have the current version since i think we made 
changes as a result of our conversation when mike, chris, and i called 
chris m from ireland).

we might start with one plane class (maybe even a boeing ontology that 
has manufacturer boeing) and another top level plane class that
has another restriction even on the same property such as all values 
from EuropeanCompany and just maintain a restriction that planes have at 
least one manufacturer and make a generic plane class.

is there anything we else we should report in the oep telecon today?
when is the update coming for our internal review that results from our
