We need to be able to display content ratings for games in Brazil. In the "admin settings" section of managing an app's details, there should be a field to set this rating for the app. There are 6 possibilities (http://en.wikipedia.org/wiki/DJCTQ) and the details page will consume this field to display an appropriate graphic. When working on this, keep in mind that we will have a broader ratings system in the future not limited to Brazil.
This bug is the adding the field on the admin page and storing the value in the db. This isn't about showing the value on the detail page. The last sentence of comment 0 is important - before implementation please get feedback on a plan for how we will store ratings for each country's laws. I'm happy to help and/or get help on this, but lets do it sooner rather than later.
Wil and I came up with this plan: Write a module like mkt.constants.region with ratings body and rating levels info. Add a table with (app, ratings_body, rating) rows. Add ratings body info to the regions in mkt.constants.region.
