(Not really sure whether to continue all this crossposting, anyway) >>>Steven Pemberton said: > > From: "Dan Brickley" <danbri@w3.org> <snip/> > There have been recent discussions about RDF in XHTML, for instance with > Eric Miller, sparked off by http://www.dubinko.info/writing/meta/, and it is > an agenda item at our coming FtF. There is also a new accepted TAG issue on RDF in XHTML: RDFinXHTML-35 : Syntax and semantics for embedding RDF in XHTML http://www.w3.org/2001/tag/ilist#RDFinXHTML-35 I guess we should tell the TAG about the various pointers/ideas discussed here. > One approach that has been discussed is a DTD-friendly encoding of RDF in > XHTML.

Immediate thought - when the object of a triple is a URL, how can you distinguish that from a string that looks like a URL? i.e. a triple with a URL object (in this rdf/xml) <http://www.w3.org/TR/rdf-syntax-grammar> ex:homePage <http://purl.org/net/dajobe/> . versus triple with a string object <http://www.w3.org/TR/rdf-syntax-grammar> ex:homePage "http://purl.org/net/dajobe/" . how about: <meta name="ex:homePage"> <meta rdf:about="http://purl.org/net/dajobe/"/> </meta> <meta name="ex:homePage">http://purl.org/net/dajobe/</meta> and the former is needed in this example. > </warning> > > Now, I can guess that you need yet another RDF syntax like you need a hole > in the head, but the driving factor of DTD-friendliness seems to me > reasonable, and the opportunity of having (an) RDF directly in HTML seems > good for the potential adoption of RDF. :) > It would be good if we could discuss this at the coming Technical Plenary > week; we had already pencilled in a meeting with you. > > a) When would you be available?

(I realise you > want to end before TP so *you* can use the meeting to go to CR) Sorry, I'm unlikely to be there. A further issue related to our use of <link> has been raised as a last call comment: http://lists.w3.org/Archives/Public/www-rdf-comments/2003JanMar/0221.html with discussion of the link types. Can the HTML WG accept/check that the ones in http://www.w3.org/TR/2003/WD-rdf-syntax-grammar-20030123/#section-rdf-in-HTML are appropriate to recommend? We mention meta, alternative. Thanks Dave
