Open Graph protocol - Développeurs Facebook
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.
