I know that there are some built-in objects (episode, article, tv show) and actions (watch, read , play , listen)
http://developers.facebook.com/docs/beta/opengraph/objects/builtin/
But I'm not being able to add them within my app.
The only objects (from open graph) that I can add, besides my custom objects under my app namespace, are:
website
book
profile
game
game achievement
Am I missing something here ?
