[[ From: Bullard, Claude L (Len) <len.bullard@intergraph.com> Date: Tue, 21 Sep 2004 12:24:23 -0500 Message-ID: <15725CF6AFE2F34DB8A5B4770B7334EE07206718@hq1.pcmail.ingr.com> To: 'Stuart Williams' <skw@hp.com> I think of it in the traditional sense of "ontological commitment" per Thomas Gruber. "An ontology should require the minimal ontological commitment sufficient to support the intended knowledge sharing activities... Since ontological commitment is based on consistent use of vocabulary, ontological commitment can be minimized by specifying the weakest theory (allowing the most models) and defining only those terms which are essential to the communication of knowledge consistent with that theory." ]] [[ From: Stuart Williams <skw@hp.com> Date: Wed, 22 Sep 2004 13:46:00 +0100 Message-ID: <41517408.3060604@hp.com> To: "Bullard, Claude L (Len)" <len.bullard@intergraph.com> I think what some others feel is lost from the proposal I made is the notion of a class of resource which "conveys information". ]] I find that these two excerpts shine a bright light on what I have seen as the crux of the discussion regarding the term "information resource" versus "web resource", which comes down to where the line is drawn between the web and semantic web layers. There are those who would like to see more semantics about resources defined at the web layer, reflecting the usage and user perceptions of the web as a vehicle of information interchange, in particular the definition of class of resources corresponding to bodies of information, i.e. "information resources". There are others who see such definitions as not critical to the operation and use of the web layer, specifically, but rather feel that such a definitions would be better expressed using the machinery specifically designed for such purposes at the semantic web layer. I find Thomas Gruber's excellent words about minimizing ontological commitment to strongly favor this latter alternative; which I feel is effectively captured in Stuart's recently proposed text, per http://lists.w3.org/Archives/Public/www-tag/2004Sep/0151.html which reflects the optimal and minimal ontological commitment that should be made in this matter, at the web layer specifically (which I understand to be the specific scope of focus of AWWW). That said, I also consider myself one of those individuals (long) wishing for an official, formal definition of commonly percieved classes of resources central to web usage, including the class "information resource", and encourage the W3C to actively facilitate their definition, ideally in the form of an RDF schema which captures the semantics of these fundemental classes of resources and their essential relationships in a formal manner; an effort to which I would be very happy to contribute.
