http://developers.facebook.com/docs/opengraph/ At Facebook's 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 we launch new products (photos, places, etc.). In 2010, we introduced an early version of Open Graph, an extension of the social graph, via the Open Graph protocol , to include 3rd party web sites and pages that people liked throughout the web. We are now extending the Open Graph to include arbitrary actions and objects created by 3rd party apps and enabling these apps to integrate deeply into the Facebook experience. After a user adds your app to their Timeline, app specific actions are shared on Facebook via the Open Graph.

Web 2.0 Awards

Rated, Ranked, and Awarded After scouring the web for Web 2.0 sites both new and old, we developed a "short list" of over three-hundred sites in forty-one categories. From there, we had some of the web's best bloggers, entrepreneurs and business people vote on winners, narrowing the field to 174 place-getters and Honorable Mentions. The inaugural Web 2.0 Awards were staged by SEOmoz in 2006. This third edition was compiled by Jane Copland , SEOmoz's social media expert. The Awards were designed by Ben Bleikamp , with winner's prizes designed by Timothy Christensen .
