RDFa

A new edition of the RDFa Primer has been published. This brings it into line with the latest draft of the RDFa Syntax specification.

The title says it all: RDFa.info now has a wiki. Please come along and join in the fun!

We’ve reached a point where new editors’ drafts of the syntax and processing document, and an introductory primer are available, ready to be reviewed by the W3C’s Semantic Web Deployment Group at their next face-to-face meeting.

Take a look. RDFa is pretty close to completion…and now the fun can really begin.

And once more Bob DuCharme has written an exquisite article, published by IBM developerWorks, called Put XHTML 2 to work now. To sum up the main idea of the article:

Many publishers that store content in XML have always known that using an existing, standard schema (by which I mean a W3C Schema, a RELAX NG schema, or a DTD) was better than creating their own from scratch. They looked at DocBook and found it too complex; they looked at HTML or XHTML 1 and found it too simple. For many of them, XHTML 2 will hit a sweet spot between the richness of DocBook and the simplicity of XHTML 1 that makes it a perfectly good format for storing content, whether that content has to be converted to other formats for delivery in various media or not.

What I liked best? The section Easier addition of metadata, where he writes about RDFa

Fresh from the Mindswap Blog: Ora Lassila and James Hendler have an excellent article about Embracing Web 3.0 in IEEE Internet Computing. For short, Web 3.0 is Semantic Web and Web 2.0 - with RDFa being one of the important enabling technologies:

W3C is working on new approaches, such as Gleaning Resource Descriptions from Dialects of Languages (GRDDL) and RDFa, to standardize the linking of structured data with instructions on how to transform or embed data into existing Web resources.
