Since I was introduced to the RDFa framework just over a month ago by the Mysterious Mr. Webnauts I've been nothing but exited about the framework and how it can enhance the search results for ourselves and our (us SEOs) clients' websites.
There are a lot of people who still have very little knowledge that the RDFa framework exists and believe SEO hasn't changed much but it has.
Now under certain conditions and with certain search strings on both Google and Yahoo we can find instances where the RDFa framework integrated within a website can enhance their listing in the search results.
This page on AListApart.com gives a little introduction into the RDFa framework and shows how the search results can be enhanced by it's usage/implementation.
Are you familliar with the RDFa framework? Are you an SEO who has been integrating RDFa into your website documents - for yourself or your clients?
As I mentioned before: although some people feel it's useless to get into the RDFa and SEO all I can respond with is that Google and Yahoo are now displaying data in the search results from websites that do have RDFa integrated into their code and if a client asks us to have their listings in the search results show this information/data then we as SEOs need to take the RDFa seriously as I'm sure the question will arise one day, one way or another in time.
