Re: Recording & chat transcript from 19th February meeting now on Wiki

I recall that we hit on "versionOf" at some point (it doesn't show up in 
the chat). It seems to me that we need to decide if that has the 
semantics of "sub-class" or "related" -- in other words, whether it is a 
vertical or horizontal relationship, and if horizontal then do we see it 
as an inverse property?

I would probably answer "no" to that last question, and suggest that 
"versionOf" simply says that A is a versionOf B with no implication as 
to which came first or which is dominant. It would be correct to say 
that A is a versionOf B and B is a versionOf A, but we would not infer 
that A is a versionOf B and B is a versionOf C means that A is a version 
of C (not transitive).

I realize that this is NOT what "instanceOf" is intended to do because 
instanceOf requires the link to be aware of class/sub-class 
relationships. One could use "versionOf" in place of "instanceOf" in the 
proposal, and that would then define a class/sub-class relationship 
between things. I'm wary of this because I think the real world case is 
messier than class/sub-class.
