I objected at the beginning to the way this was going, I object now to how it sounds. The problems are that (1) this implies that Rich KR is somehow better and more valuable on the web (largely unproven), (2) it takes an unflattering approach to describing OWL in its emphasis, and (3) it doesn't emphasize the important point it is trying to make (that sometimes extending OWL with rules is a good thing, but the rules syntax needs to be commensurate with the syntax OWL is in, (4) The syntax used in the example is not the normative exchange syntax for OWL and this further obfuscates the point being made. I do not object to having a section (Renamed "extending OWL") which 1 - shows how rules can extend something in OWL (I think the uncle example is very misleading, by the way, unless you want to get into a discussion of safe grounding - seems odd to have to insist on including the "person(?y) and person(?x) in the rules when the WG hasn't even addressed this issue) 2 - that does not have any italics nor use the incorrect word impossible (btw, it is more than possible to do this in OWL,, where I can extend syntax, it is not possible to do this in OWL DL as written) 3 - makes the last sentence, which is more important than all the rest of the example, more evident 4 - is retitled to emphasize that this is about the standard format for extending, not about the extending per se (there are many other ways to consider extending languages w/or w/o rules) btw, less anyone wishes to claim my objections here are more political than technical, I confess you are absolutely right. THe WG process is inherently political, and that is why I pay to belong to the W3C so I can help get the politics right. -JH -- Professor James Hendler Director Joint Institute for Knowledge Discovery 301-405-2696 UMIACS, Univ of Maryland 301-314-9734 (Fax) College Park, MD 20742 http://www.cs.umd.edu/~hendler Web Log: http://www.mindswap.org/blog/author/hendler
