 Of these four possibilities, we describe _mutable reverse_, of which the Library of Congress's activity stream is an example, and _immutable forward_, of which Getty Vocabularies' activity stream is an example. Regarding the remaining two possibilities, _mutable forward_, while feasible, requires the entire stream to be processed at each release, as there is no way of establishing where in the stream a change might occur. _Immutable reverse_ is inherently infeasible, as it requires that new content appear first, but on a page that cannot be changed.

 The Library of Congress' mutable reverse approach is inherently the most compact, as any given entity appears in the stream exactly once, at its most recent
 point of modification. However, this is accomplished by completely regenerating the activity stream in its entirety whenever new content is
