Frank, This is a fine diagram, but notice that "Logic" is a little block on top of RDF-schema, for example. This tells me that things like RDF-schema are seen as prior to logic by at least Berners-Lee and perhaps others. John's point was precisely the opposite. He would not disagree with you about the choice of establishing the lexicon first, which has been done by virtue of the fact that Unicode and URIs are at the bottom. However, I think he would vehemently disagree, as do I, that "Logic" is somehow less basic that "RDF-schema" or "XML-schema". As I pointed out in my previous post, these languages are often poorly specified by the standards of mathematical logic (although Pat Hayes has been kind enough to fix that for RDF). This is another example of the hijacking of a perfectly respectable term like "Logic", which is being used here as a coverterm for "Rules" or "Constraints". But RDF-schema and XML-schema already have the power to represent some classes of constraints. Are these constraints somehow independent of "Logic"? Likewise the use of the term "Ontology Vocabulary" indicates confusion. The logic needs to be nailed down before one can specify an "Ontology Vocabulary" in that logic. This is another example of Orwellian revisionism on the part of the Web ontology community. I would urge them, for the sake or clear and rational discourse, to stick to the common interpretations of these terms. .bill -- Bill Andersen Chief Scientist, Ontology Works 1132 Annapolis Road, Suite 104 Odenton, Maryland, 21113 Mobile: 443-858-6444 Office: 410-674-7600 Web: http://www.ontologyworks.com
