  An Activity is a subtype of {@link Object} that describes some form of action
  that may happen, is currently happening, or has already happened.
  The {@link Activity} type itself serves as an abstract base type for all types
  of activities.  It is important to note that the {@link Activity} type itself
  does not carry any specific semantics about the kind of action being taken.

  description: |
    Describes one or more entities that either performed or are expected to
    perform the activity.  Any single activity can have multiple actors.
    The actor MAY be specified using an indirect {@link Link}.

  compactName: object
  uri: "https://www.w3.org/ns/activitystreams#object"
  description: |
    When used within an {@link Activity}, describes the direct object of
    the activity.  For instance, in the activity "John added a movie to his
    wishlist", the object of the activity is the movie added.

- pluralName: targets
  singularName: target
  singularAccessor: true
  compactName: target
  uri: "https://www.w3.org/ns/activitystreams#target"
  description: |
    Describes the indirect object, or target, of the activity.  The precise
    meaning of the target is largely dependent on the type of action being
    described but will often be the object of the English preposition "to".
    For instance, in the activity "John added a movie to his wishlist",
    the target of the activity is John's wishlist.  An activity can have more
    than one target.

  singularName: result
  singularAccessor: true
  compactName: result
  uri: "https://www.w3.org/ns/activitystreams#result"
  description: |
    Describes the result of the activity.  For instance, if a particular action
    results in the creation of a new resource, the result property can be used
    to describe that new resource.

- pluralName: origins
  singularName: origin
  singularAccessor: true
  compactName: origin
  uri: "https://www.w3.org/ns/activitystreams#origin"
  description: |
    Describes an indirect object of the activity from which the activity is
    directed.  The precise meaning of the origin is the object of the English
    preposition "from". For instance, in the activity "John moved an item to
    List B from List A", the origin of the activity is "List A".
