I just read the new draft (Feb 20), as I had the previous one (Feb 7). I'm generally happy with it, but wanted to raise a couple concerns before the deadline: 1) The "Explicit ontology extension" section hints that ontologies are our primary building blocks rather than classes and properties. I think part of the beauty of RDF/DAML+OIL is the ability to use or extend any class or property without much concern for the ontology boundaries ("ontologies" are currently just a loose collection of classes and properties sharing a common URI sans fragment). I would hate to see this change. 2) I fear that the current "Classes as instances" description won't convey sufficient understanding to an outside reader (a Class is an instance of class Class after all). Perhaps we need to include the A320 aircraft type example: we want to be able to specify certain properties (maxSpeed, passengerSeats, range, etc.) common to all A320's without having to enumerate them for each instance.
