I think there are other points and I'm borrowing the following from Pat as I couldn't express it better... The point is that publication of RDF, when considered as a social act, constitutes a publication of some content which is defined by whatever normal *social* conditions are used by the publishers of any terms in the RDF to define the meanings of those terms, even if those meanings and definitions are not accessible to the formal semantics of RDF; and, moreover, those meanings are *preserved* under any formally sanctioned inference processes. In a nutshell, the formal entailments of social meanings are themselves part of the social meaning. The point is also that we cannot use a single notion of 'meaning' to say this properly, since of course the formal entailments cannot themselves utilize the social aspects of meaning which are included in *informal* aspects of the publication, such as in a comment which is opaque to any likely RDF inference engine or machine processor. Social meanings can be, as it were, transferred or carried by formal entailments, but they cannot be incorporated into the formal entailments. -- , Jos De Roo, AGFA http://www.agfa.com/w3c/jdroo/ Christopher Welty <welty@us.ibm.com> To: www-webont-wg@w3.org Sent by: cc: www-webont-wg-requ Subject: Re: issues to be resolved before last call (rdfms-assertion) est@w3.org 2003-01-18 03:43 AM I completely agree with Peter here. I've read the relevant documents on the RDF side and I am in quite a state of shock. This has NOTHING TO DO with OWL, (or with RDF for that matter). You simply can not, as a matter of course, define as part of a language how much responsibility people have for what they say in that language. That is not the role of technology, nor of standards. It is the role of law. The W3C is not a law-making body, not in the US nor anywhere else in the world. Dr. Christopher A.

I believe that they will be unacceptable to Lucent as well, and also to just about any legal entity. Note that the impact of social meaning is that any RDF document that uses a URIref includes the entirety of the social meaning of any document that can be found by dereferencing the URIref. See Section 4.5 of the RDF Concepts document for a particularly informative example. Peter F. Patel-Schneider Bell Labs Research Lucent Technologies
