Friendica adds some addictional fields:
+- author: a user object, it's the author of the item. In case of a reshare for legacy reasons the "user" field doesn't show the real author. This field always contains the real author of a post.
- owner: a user object, it's the owner of the item.
- private: boolean, true if the item is marked as private
- activities: map with activities related to the item. Every activity is a list of user objects.
