This week I've been having a refresher / catch-up on all things semantic and rdf on the net; from a developer standpoint.
To save everything going to waste, here's a quick list of multiple handy resources which I've found (save you a bit of googling and time).
XHTML + RDFa and related techs.
- Wikipedia RDFa
- RDFa info
- W3C RDFa Primer, RDFa for HTML Authors, RDFa Syntax, RDFa Usage Scenarios
- Google RDFa Support help for webmasters.

- OpenLink Virtuoso Open Source Database (RDBMS, ORDBMS, virtual database, RDF, XML, free-text, web application server, file server, sparql, ws-* etc)
- Notation3 on W3C, Wikipedia

Hopefully that'll be enough to get most people going!














Hi Nathan,
A good list, but forgive me for flagging up my own posts here; you have missed a ton of resources that are available on my company web-site: http://webbackplane.com/rdfa.
There you'll find blog posts, videos of presentations, slides, and so on, about various aspects of RDFa, and going back to 2004.
Also, there are two introductory articles on RDFa, on A List Apart: see Introduction to RDFa and Introduction to RDFa II.
All the best,
Mark
cheers for those mark - some good additions :)
