At Facebook core is the social graph, people and the connections they have to everything they care about. Historically, Facebook has managed this graph and has expanded it over time as it launch new products (photos, places, etc.). Now Facebook Intoduce the Facebook Developers Open Graph BETA docs and tools for developers to test along with a prelease of the facebook new timeline.

The Open Graph allows apps to model user activities based on actions and objects. A running app may define the ability to "run" (action) a "route" (object). A reading app may define the ability to "read" (action) a "book" (object). A recipe app may define the ability to "cook" (action) to a "recipe" (object). Actions are verbs that users perform in your app. Objects define nouns that the actions apply to. Facebook Already got some default examples that available for developers to test it and see how it works.

After a user adds your app to their Timeline, app specific actions are shared on Facebook via the Open Graph. As your app becomes an important part of how users express themselves, these actions are more prominently displayed throughout the Facebook Timeline, News Feed, and Ticker. This enables your app to become a key part of the user and their friend experience on Facebook.
