Facebook Markup Language

Facebook Markup Language ("FBML") is a variant-evolved subset of HTML with some elements removed. It allows Facebook Application developers to customise the "look and feel" of their applications, to a limited extent. It is the specification of how to encode content so that Facebook's servers can read and publish it, which is needed in the Facebook-specific feed so that Facebook's system can properly parse content and publish it as specified.[27] FBML set by any application is cached by Facebook until a subsequent API call replaces it. Facebook also offers specialised Facebook Javascript (FBJS) and library.[28]

By the end of 2010, Facebook will no longer be accepting new FBML applications, but will continue to support existing FBML tabs and applications. Facebook recommends the use of iframes for new application development.[
