One Graph to rule them all discusses integrating applications with the Open Graph by publishing custom actions and objects. It provides an overview of the key elements - the user, object, and action. It also touches on publishing actions via the Facebook JavaScript SDK or wrappers like Koala, surviving Facebook review, and alternatives to Open Graph like scores and achievements.

3. ¿How to publish actions
in the Open Graph?

4. 1. Get a wrapper
gem install koala

5. 2. Get access to the user’s graph
graph = Koala::Facebook::API.new(user_token)

6. 3. Publish your action!
graph.put_connections("me", ”my action
name", :my_object=> my_object_url)

8. Not so fast!

9. ¿What is the Open
Graph?

12. Elements of the Open Graph

13. The User

14. Asking for permissions:
publish_actions

15. Merging with publish_stream
publish_stream permits you to write in the user’s wall.
Now publish_actions include “basic” capabilities of
publish_stream.
Facebook is trying to simplify its permission system.

16. The Object

17. Define the object with metatags
og:url
og:title
og:description
og:image
og:type

18. Using the object URL as a landing

19. A typical issue: caching
Facebook caches the URL of the objects.
Facebook Debugger cleans the cache. Use it!

20. The Action

21. The easy way: built-in Actions
Follow
Like
Listen
Read
Watch

22. Better create your own!

23. Publishing your actions
Client-side: Facebook Javascript SDK
Server-side: Choose your wrapper!
Server-side & Background: Sidekiq, Resque...

24. Meanwhile, in Ruby…

25. Surviving Facebook Review

26. Translating your action

27. ¿Why the Open Graph?

30. Alternatives

31. Scores
Pretty good choice in simple, “closed” games.

32. Achievements
Every achievement has points associated.
A game has 1000 points to distribute across all the
achievements.
The visibility of the achievement depends of the points.

33. Publishing in the wall

34. Things to remember
Open Graph is really simple to use.
Just adapt your application to Facebook way
of life.
Greatly improves your visibility.

35. Now it’s true.
