It looks to me like the events in this model are more fine-grained than we need in the History system.  In this CCM work it looks like you capture the fact that property X was changed to Y.  In the History system, we'd probably model something more along the lines of here was the object before, this is the event of an admin changing the metadata, this is what the object looked like after that event.
