Microformats vs. RDFa

So I got accepted into Yahoo's Search Monkey application platform. I don't really know a whole lot about it yet, but there was a lot of mention about eRDF, RDFa, and microformats in the documentation, since these are the markups which Search Monkey will understand. This got me thinking a bit, since I recently mentioned to my co-workers that we should be implementing microformats. After reading more about RDFa, it seems like microformats are less extensible, but they are already pretty widely supported. I'm not sure about RDFa.

I plan on looking more into this, but this post is essentially just for me to bookmark a few of the articles I've found which look like they'll be good resources.

• Why RDFa is the only web-scaleable metadata format for next-generation search engines
• The Future of RDFa
