Why use "content" for an explicit object/value? We already have too many words for this, and that particular word is kind of subject/object neutral so IMO could lead to confusion, eg folk come to see this as a text/URI alternator, and then use it to indicate a subject, rather than "about". I'd suggest an unmistakeable neologism like 'pvalue' or 'propvalue' (I know its ugly, thats the point :-) 2. Congratulations for inventing CURIEs, but I bet you ought to call them CIRIs or COIRIs now, and I bet you ought to define them relative to IRIs rather than to URI/Qnames. 3. If I follow this, the only way to include a 'pure' RDF triple in RDF-A is to create an XML <li> element with an id. So all RDF-A triples have to have separate XML ids. (??) If so, this seems like an unnecessary burden. Surely it wouldn't be hard to allow RDF-A to include chunks of 'pure' RDF (by which I mean, not explicitly linked to ids of items in the XML itself) more or less unchanged from RDF/XML, or some other RDF notation in common use? I think this might be important for deployed applications, since it would allow RDF/XML to be smoothly transitioned into RDF-A, and would also allow RDF-A to encode OWL/RDF annotations without incurring a needless notational burden. Also, giving an id to a whole RDF (sub)graph fits naturally with the 'named graph' idea, unlike giving an id to every triple. 4. This is probably not appropriate for XHTML, but I can't help thinking that it would be really nice (and even more compact) if one could use CSS to attach properties and datatypes to spans. Just a passing thought :-) Pat Hayes >-Ben > >PS: please forgive the futuristic date in the URI, the content >should clearly state the right draft target date as well as the CVS >last updated date. -- --------------------------------------------------------------------- IHMC (850)434 8903 or (650)494 3973 home 40 South Alcaniz St. (850)202 4416 office Pensacola (850)202 4440 fax FL 32502 (850)291 0667 cell phayesAT-SIGNihmc.us http://www.ihmc.us/users/phayes
