CategoryGroup

Ads may be grouped into one or more categories, such as Dining, and these categories can form a hierarchy. For example, a Dining category could be a parent of the Italian Dining category.

A CategoryGroup models a category along with its associated subcategories. Ads can appear in multiple category groups but are guaranteed to appear in at least one.
