Not having seen anything yet, it's hard to say whether it's interesting, either practically or theoretically. Kendall - you've seen the model theory! This has been said all along to be a subset of OWL, so the OWL documents provide the model theory (and reference, and examples, and test cases, etc.) While I disagree that the TFs are motivated by "theoretical aspects" only, they have the virtue of having been written down and can be discussed publicly. Well of course you haven't seen it yet - we're discussing whether this WG should be the place to create one, whether people will submit through the notes process, or whether this will occur in some other WG. I certainly have opinions as to what I'd like to see in a language, but that's not the discussion we've been having in this thread. To be clear, my comment is that, as I have stated publicly, and continue to do so, my WG made a mistake in not considering users enough in the design of the "lite" fragment of OWL. I do not want to see another WG make the same mistake, this is called experience. So I ask the WG to either take on the issue by adding usability to the design criteria (as many WGs do) or to remove this fragment from the scope of THIS working group so they can be worked on by a group that will be responsive to the commercial comments we've been hearing. -JH p.s. note that this is only one of many things in the scope of this WG, so this is only an argument at the moment on this small piece of the charter, not on chartering the WG more generally -- Prof James Hendler hendler@cs.rpi.edu Tetherless World Constellation Chair http://www.cs.umd.edu/~hendler Computer Science Dept 301-405-2696 (work) Rensselaer Polytechnic Inst 301-405-6707 (Fax) Troy, NY 12180
