Uh...we had long, extensive discussions of precisely this. I raised it  
as an issue thinking it would be a nice helpful thing. I came to  
believe that it's a very bad idea, at least given what we know.

I don't believe that's remotely compelling. There's all sorts of  
properties about an ontology you may wish to mine or filter on:

I object. This is not a "extra small thing that leads to hell". This  
is a feature that was discussed extensively by the working group and  
rejected:
	http://www.w3.org/2007/OWL/tracker/issues/111

I'm sorry, that Frank  finds the discussion in 111 "unconvincing" is  
not new information sufficient to reopen the issue. We were convinced.  
If Frank wants us to reconsider he must *argue* the case, not merely  
dismiss our discussion.

Remember I *raised* this; I *championed* this; I became convinced that  
any solution we came up with is unworkable. Prima facie we should  
respect that, and our own process.

(Note he doesn't raise the issue of imports at all :()

Furthermore, this is exactly the sort of thing that can be done, at  
lower cost and risk, outside the working group.

(The OpenCyc example is particularly silly...I don't believe it's  
particularly difficult to do profile checking on it, or on NCI, or on  
SNOMED...again, see the TONES repository.)

Cheers,
Bijan.
