Type Definition activitystreams::activity::Undo

type Undo = ActorAndObject<UndoType>;

Indicates that the actor is undoing the object.

In most cases, the object will be an Activity describing some previously performed action (for instance, a person may have previously "liked" an article but, for whatever reason, might choose to undo that like at some later point in time).

The target and origin typically have no defined meaning.

This is just an alias for Object<UndoType> because there's no fields inherent to Undo that aren't already present on an ActorAndObject.
