Hello, is there a way to implement the 'Composite' pattern in Og?

Probably it should looks like this:

    class Item
      property :name, String
      belongs_to :parent, Item

    class Container < Item
      has_many :items, Item

    class Image < Item; end
    class Post < Item; end
    class Folder < Container; end

But i failed to achieve this with Og :(

Does ActiveRecords or DataMapper support this feature?
