Hi all, http://www.w3.org/2001/sw/BestPractices/HTML/2006-04-24-rdfa-primer is the current draft of the RDFa Primer. Yes, I'm trying "RDFa" on for size :) The usual disclaimer applies: this document has no formal standing within W3C and is subject change at any time. Important changes to note: 1) the Abstract is new. 2) Section 2 is entirely rewritten, thanks to a very productive offline discussion with MarkB (and a suggestion due also to DanC). In particular, we stay away from the URI ambiguity issues by using vocabularies (iCal and vCard) that are less people-oriented. This also seems like the right way to show people the power of RDFa: there are interesting, natural things to share in current web pages, like events and contact information, that RDFa can address quite well. 3) Section 3 and 4 are mostly unchanged, except for the dc:creator issue. From looking at the Dublin Core documentation, it seems that dc:creator should be a literal. So I made it a literal, and changed rel="dc:creator" to property="dc:creator". Of course, it's currently an XMLLiteral, so there may be some remaining issue to address here. Note that I have *not* addressed Alistair's comment that a XHTML fragment cannot also be a physical resource. Like Mark, Jeremy, and Pat, I believe an XHTML fragment *can* also be a camera or a person. I'm sure we'll face opposition on this problem, but this goes to the core of whether XHTML can be a first-class serialization of RDF. If it can't, it seems to me that the Semantic Web and the Clickable Web are hopelessly disjoint, and we've got a problem bigger than this task force. 4) Section 5 (and eventually additional sections) will dig into specific vocabularies, like FOAF, geoURL, etc... for readers who are particularly interested in these specific vocabularies. So far, they're not written up, and will likely be written up in WD #3 (next WG....) Note that I have not had time to address all comments by reviewers. I'm going to try to do that over the next 2-3 days. If you catch something specific, let me know ASAP. -Ben
