A new edition of the RDFa Primer has been published. This brings it into line with the latest draft of the RDFa Syntax specification.
David Peterson gives a good analysis of what Yahoo’s announcement means for sites wanting to get semantic information into search results.
Just found out about RDFa from the Yahoo announcement? Read the Primer and have some questions? Deploying RDFa on your web site and want some guidance with specific examples? We’ve got a new mailing list for you:
public-rdfa@w3.org
You can find subscription information and full archives at:
http://lists.w3.org/Archives/Public/public-rdfa/.
Or, if you prefer to lurk for now, subscribe to the RSS feed.
(If you’re developing an RDFa parser, have a Last Call comment on the RDFa Syntax, or want to discuss some deeply technical aspect of RDFa, you should feel free to email the task force at its existing address: public-rdf-in-xhtml-tf@w3.org.)
As announced by Yahoo! yesterday, they will support soon semantic technologies:
In the coming weeks, we’ll be releasing more detailed specifications that will describe our support of semantic web standards. Initially, we plan to support a number of microformats, including hCard, hCalendar, hReview, hAtom, and XFN. Yahoo! Search will work with the web community to evolve the vocabulary framework for embedding structured data. For starters, we plan to support vocabulary components from Dublin Core, Creative Commons, FOAF, GeoRSS, MediaRSS, and others based on feedback. And, we will support RDFa and eRDF markup to embed these into existing HTML pages. Finally, we are announcing support for the OpenSearch specification, with extensions for structured queries to deep web data sources.

The title says it all: RDFa.info now has a wiki. Please come along and join in the fun!
TopBraid Composer is a modeling environment for developing Semantic Web ontologies and building semantic applications, built as a plug-in for Eclipse. In part of the description for the product, it says:
“RDFa and GRDDL are evolving W3C standards to embed semantic markup in XHTML pages. Composer can parse such documents to extract RDFa metadata from HTML pages. The metadata can then be treated like any other RDF source, and users can perform DL reasoning or SPARQL queries on it. Together with the other data integration capabilities and visualization tools Composer can be used to develop mash-up applications. TopBraid is also a comprehensive RDFa Editor.”
In the OpenOffice.org blog GullFOSS, this week’s Development at a Glance mentions that they have started work on support for RDFa and RDF XML metadata in ODF 1.2 documents. ODF, or the Open Document Format, is the document format for electronic office documents produced by the suite of programs that make up Open Office.
On Bob DuCharme’s blog, an interesting perspective from Sarah Bourne, the Chief Technology Strategist for the Commonwealth of Massachusetts:
If Massachusetts pursues enriching our content, RDFa seems a more likely candidate. We prefer to adopt things that have been created and promulgated by standards bodies: they are more stable, the deliberative process surfaces and resolves problems beforehand, and are the only reliable basis for interoperability.
