a few references:  (am i supposed to send this to the full oep list or just us?  if just us, things are not archived....)

We had an OEP telecon today and had some lively discussion on the part note. 

First of all we all agreed it is a good start.  Despite numerous philosophical/ontological issues creeping into the discussion, we reached a consensus that for the simple note we shouldn't change it too much, and consider deeper issues for the longer note. 

We discussed for a while specific criticisms to the example, its general usefulness and correctness (wrt reality).  I suggested a change to a medical example, for which these criticisms had ready answers and in particular lay in Alan's expertise - even more, we could take the examples from actual usage.  In the end we convinced ourselves that this example was a good place to start because of its familiarity and general reusability.  Evan took the action to work on a corrected version of the example that is accurate wrt the anatomy of cars.  (Evan, be sure to include the critical issue of unsprung weight). 

Some specific comments: 

- It woudl be very useful to mention in this note the limitations on transivity in OWL DL (no cardinality restrictions) and perhaps exemplify it. 
- Brush up the introduction section.  Rephrase "the key thing to represent about PW relations is that they are transitive", which seems to strong .  Add a brief discussion to the point that there are many "kinds" of PW relations and try to describe which one this note deals with. 

Also, Deb and perhaps others will send suggested references to add. 

I am willing to take a pass on it to address these issues.  Is the editor's draft the latest version?
