Facebook had recently introduced Open Graph protocol, Open Graph API allows websites, iPhone/ iPad Applications, Android Apps to draw information about more objects than simply people, including photos, events, and pages, and their relationships between each other.
Further it also enabled “actions” and “objects” created by third-party apps (including iphone / android applications) and enabling these apps to integrate deeply into the Facebook experience.
Before Open Graph was introduced, users were able to connect to a post or object in a app via the like action only. Now, developer can model user interactions in a btter custom actions (entities) and objects (interactions) for richer connections with your users.
Below diagram illustrates the flow of how this works:
We are currently working on creating a test / prototype project to test the entire flow and we will post the output in next couple of days on our blog.
