Facebook updated its checklist for open graph applications last month, and just added some clarifications. The Facebook developer blog addressed the use of user messages, tagging, and user photos, stating that for all of these areas, developers must follow the instructions in the sites documentation, and provide detailed reproduction steps:

The first step requires you to outline concise, step-by-step usage instructions to trigger the action. Provide the necessary information (including URLs to staged apps, login details, navigation steps, button/link clicks, etc.) in English for our team of reviewers to reproduce the actions in your app.

Another step Facebook added lets developers take a look at their submissions one last time, as well as to track their statuses with email notifications.

Facebook also just rolled back its Timeline for brands to 1000 A.D., to better accomodate older businesses.
