Platform Core Components
From Facebook Developer Wiki
Facebook Platform comprises a number of core components, including:
- The server API, which consists of a number of methods that let you add social context to your applications.
- The JavaScript SDK, for Facebook Connect implementations and IFrame applications.
- FBML, Facebook Markup Language, which allows you to integrate your application into Facebook.
- XFBML, an extension to FBML, which lets you incorporate FBML into Facebook Connect implementations and IFrame applications.
- FQL, Facebook Query Language, which lets you quickly and easily query for Facebook user data without using the API.
- FBJS, Facebook's method for letting developers incorporate JavaScript into their FBML applications.
