"events are primarily linguistic or cognitive in nature. That is, the world 
does not really contain events. Rather, events are the way by which agents 
classify certain useful and relevant patterns of change." 
I read many event ontologies, but this one is the most idiosyncratic, softly 
Wonder if it is in the Linked Data Cloud. If yes, then it hardly will give 
any refreshing rainwater.
The world without events is the world without any precipitation as well :).

foaf:sha1 exists, but that might not be much use if you if you want
to...    (05)

That's probably a pretty good start.    (09)

If you add in an events ontology (and I'd recommend starting with
Yves Raimond's one and building on top of it) then you should be able
to define a EntryChange class as a subclass of Yves' ev:Event class
with accompanying previousVersion (subproperty of ev:factor) and
subsequentVersion (subproperty of ev:product).    (010)

Building on Yves' ontology for tracking document changes is more or
less what I've done here:    (011)
