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'm currently working for a fairly large "travel" company. It seems like most of the projects I've worked on since starting there have required some sort of calendar functionality to display ticket price, hotel availability, etc. I'm a strong proponent for using semantic markup (as I hope all of our web developers are) and have been wondering - how do you semantically represent a calendar using HTML and CSS?
