Facebook Markup Language Primer

The Facebook Markup Language (FBML) is the heart of the Facebook platform. You might see some folks referring to FBML as “fancy” HTML tags, but it actually does a little more than static HTML because it has a dynamic connection to the Facebook back end. If you have developed any web applications in ColdFusion or JSP (using JSTL), programming with FBML will be very familiar. The Facebook Markup Language is described on the wiki site as an “evolved subset of HTML,” so you have many of the same tags available to you as you do in normal HTML, but you also get a much richer tag set that allows you to code myriad interactions with the users very quickly.
