It will be an official W3C standard in the next couple of months and will be supported in XHTML1.1 and XHTML2. Some are currently working to get it integrated into a new HTML4 DTD as well. No putting the semantic genie back in the bottle. :) > You can embed it in XHTML. Why is having it in HTML necessary for creating > statistical models? I was speaking generally in that case because I thought you were speaking generally... this seems to have caused confusion. Apologies for that. If we are to be very specific, you do not /need/ RDFa attributes in HTML5 to create statistical semantic models. You could build the same models from all of the HTML4+RDFa, XHTML1.1+RDFa, and XHTML2 documents out there. It would also be easier to check those documents for NLP/semantic correctness with the RDFa markup embedded in the document. Statistical models are just one approach among the many that would be used to perform NLP correctness verification. You would not be able to depend solely on statistical models. So while you are technically correct, not having any sort of robust semantic expression mechanism in HTML5 deprives the content from having multiple paths to validating the document semantics: - The page's NLP based semantic model verified against RDFa model. - The page's Statistical model used to verify parts of the RDFa model. -- manu -- Manu Sporny President/CEO - Digital Bazaar, Inc. blog: Bitmunk 3.0 Website Launches http://blog.digitalbazaar.com/2008/07/03/bitmunk-3-website-launches
