Hi Alan,

What you suggest certainly provides a way of handling versioning, but in
many environments, the additional repository features seem to be
requirements. You almost always want to know who made a change, what the
change was, alongside other provenance information - and of course, make
this information machine readable (as opposed to a text note) seems
desirable for this community :P.

As I'm sure you're aware, when considering the quality and evaluation of
ontologies, identifying the state of an ontology throughout its lifecycle
also becomes quite important. Rafael S. Goncalves, Maria Copeland and their
colleagues provide an interesting set of analyses on how ontologies differ
through multiple versions [1] [2] [3].

Of tangential (but closely related) interest to versioning, people might
want to take a look at this year's Ontology Summit 2013 which focuses on
"Ontology Evaluation Across the Ontology Lifecycle" [4]. Of particular
interest may be the talk on the lifecycle stages (and from that one can
extrapolate requirements for versioning that would faciliatae higher
quality ontologies) - particularly Hanz Polzer and Mary Balboni's
contributions [5].

PS - Thanks for the response, will follow up offlist :D!
