RE: Object Role Modelling (ORM) or UML or ?? for designing Schema s

Based on Walter's description, yes.  And a mozarella one at that. 
If the delivery service forwarded the message, they better route 
it to the right Chinese restaurant.  If I sent it directly, 
I better know (apriori) they make a fine mozzarella pizza.  
If they can't, On Error Try.  No problem:  call me so I 
can send the order to Dominos and make a note to myself 
to use a different message port on next call.  Meanwhile, 
I will route messages to a list of subscribers to 
do the same.

Is it about expectations or testing the results of 
expectations on error?  A semantic web should be 
built only for things to which commitment is reasonable 
in the context of resources.  I think the phrase was 
"useful things".

Why do we need conceptual models?

But would you expect to get pizza from a Chinese take-out restaurant?

I think you'd rather that they gave you a phone call (or electronic 
message) if they didn't have a good way of processing your pizza request.

And what would you do if the delivery person showed up with the take-out 
place's interpretation of a 'pizza'?  You sent them the order, after all!
