For my evidence I refer to Ramanathan Guha (Netscape rep on RDF WG) http://lists.w3.org/Archives/Member/w3c-rdf-syntax-wg/1997Dec/0040.html and Ralph Swick (W3C rep on RDF WG) http://lists.w3.org/Archives/Member/w3c-rdf-syntax-wg/1997Dec/0040.html These two are the editors of the RDF parts. Their comments are unequivocable. I am not allowed to quote the drafts in public, under the archive rules from W3C. However, I can quote what I wrote which prompted their acknowledgement: http://lists.w3.org/Archives/Member/w3c-rdf-syntax-wg/1997Dec/0039.html # As far as I could find so far, the only difference from # draft RDF that is required to allow me to use a standard # XML markup declaration is this: to shuffle the element type # name of property elements into an attribute (here "RDF:Name"), # and to use "RDF:Property" as the element type name instead. > Inflammatory statements like this are defensible only when they're > accurate. This one is not. See above. This is the third time we have had this discussion now Tim. Let me say it again. RDF can use standard XML declarations if they want to. They don't want to. That is their choice, and I wish them well. People should not get the idea that RDF's choice is evidence supporting the necessity of things like XML-data (to the extent that this may occur). > It is just as easy to conclude from the evidence that XML-Data is in > direct competition with RDF and RDF-Schema.

But XML-data goes a lot further than RDF, both for better and worse, IMHO. Please don't get me wrong that I don't support XML-data and RDF 100% for what they say they are trying to do. But I think the implementation trade-offs that in them are skewed showing a bias against SGML declarations which I think is wrong-headed. In fact, the use of a regular expression syntax in content models is the single best abstraction in SGML: to replace it with a million elements somehwere in an instance, as XML-data currently does, seems to me to be getting rid of the only thing that programmers have an education to be comfortable with immediately! An idea verging on the bizarre. XML-DEV is a forum where developers get their understanding of what the markup community feels are the strengths and weaknesses of XML. And also to gauge which way the wind is blowing for technical strategy. This is why I have posted here; developers should be aware that many people have opinions which are repeatedly given but which there is little evidence for when examined. I am sure I am often in this category. Personally, I believe that intuitions are highly credible when given by a person of great expertise, especially for these complex matters where it may be that the issues can never be articulated convincingly. Tim is such a person of great expertise. The reason why RDF cannot use standard DTDs has not been articulated convincingly. But I think we should take his intuition in this very seriously, and discuss it with the seriousness such broad and confusing charges against the standard declarations warrant. If I am being inflamatory, I apologize to all to the extent I may have unintentionally seemed rude. But, since I was not wrong, I cannot apologize for that, much as I'd like to.
