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

// Example 3 (https://www.w3.org/TR/activitystreams-vocabulary/#ex3-jsonld):
//   {
//     "actor": {
