Hi Ivan, > - HTML4 is not in XML, right? I just wonder whether the very DOM > oriented processing steps would be appropriate. What seems to be > relatively straightforward is an XHTML1.0+RDFa, the question is whether > doing the corresponding DTD would be that easy. I think XHTML+RDFa is easier to define...that's true. And in terms of processing RDFa on a server, it's also slightly easier to implement than HTML+RDFa, because you can use XML tools. But a consequence of XHTML not being 'standard' across browsers, is that there is no difference between implementing an XHTML+RDFa and an HTML+RDFa parser. This is because, although an enormous number of documents are created as XHTML on the server, they are delivered to the client as "text/html", which will switch the browser into HTML mode. So anyone writing a client-side parser for XHTML+RDFa is almost certainly going to have to write it so that it works in 'HTML mode'. (Which is incidentally why I used the DOM idea to define the processing, because it works with both HTML DOMs and XHTML DOMs.) I'm not saying anything here about the original question -- I think we'll get to the HTML+RDFa side when we're ready. I'm merely pointing out that technically it's a no-brainer, because we took care to make sure that this was so. As Shane says, the only piece missing to create an HTML+RDFa Syntax is a way to set the prefix mappings. (And even then, that's only because it seems odd to use the @xmlns mechanism in HTML.) > - The real issue is, however, HTML5. And that is only where a crystal > ball would help:-) Indeed. :) Regards, Mark -- Mark Birbeck, formsPlayer mark.birbeck@formsPlayer.com | +44 (0) 20 7689 9232 http://www.formsPlayer.com | http://internet-apps.blogspot.com standards. innovation.
