XHTML+RDFa

On 16 October 2008 the W3C announced XHTML+RDFa as a recommendation (http://www.w3.org//2001/sw/anews/). IMO this is an important milestone in the process of implementing the Semantic Web. The Doctype/DTD is now cataloged and usable by the W3C Markup Validator.

By way of example of the use of basic constructs and syntax, I have composed a validated XHTML+RDFa page (http://jp29.org/rdfaprimer.php) -- just general information for those who might be interested in the development of the Semantic Web.

Sorry for being an absolute plonk but what exactly is the semantic web? So is this something different from HTML and XHTML?

It is the next direction of the Web: W3C Semantic Web Activity (http://www.w3.org/2001/sw/). No doubt XML (some via correctly served XHTML and XHTML+RDFa), RDF (Resource Description Framework) and eventually HTML5 will play important roles -- along with other new applications.

Here is a compilation of current Semantic Web references and resources (http://jp29.org/semantic.htm)

My apologies for posting this in the HTML section -- I overlooked that there is a section devoted to XHTML/XML. My lame excuse is that I am a newcomer -- in reality I failed to read instructions -- sorry.

No worries, it's been moved.

Sorry for the late response, will it be nessecary for web deisgners/programmers to learn about this new development for the future?

I seem to understand that it will help connect data across the web, but I don't understand how your example page differs from a normal XHTML document say.

Not immediately, but eventually those wishing to participate in the Semantic Web will have to.

.......... but I don't understand how your example page differs from a normal XHTML document say.

My apologies for omitting a portion of my exemplar page during the latest update -- it is included now. I composed this page to illustrate the use of the XHTML+RDFa Doctype/DTD, and the syntax of three primary RDFa elements: | about | property | typeof | together with an example FOAF (Friend Of A Friend) and Creative Commons constructs -- for those who might want to experiment with creating XHTML+RDFa pages after reading the W3C RDFa Primer and RDFa recommendation RDFa in XHTML: Syntax and Processing.

This is actually my own attempt to understand how XHTML+RDFa documents are constructed and function.
