Re: PROV-ISSUE-206: three proposals to vote on (deadline Jan 15th midnight GMT)

Hi Luc,
+1 For proposal 1.
As for proposals 2 and 3, I have a question before voting:
Now we have weakened wasControlledBy to transform it to wasAssociatedWith,
but I find that it may be confused with Usage. Usage also involves
an association between activities and entities. Would it become a
subproperty of
wasAssociatedWith? What would be the difference between a Usage and
an association which has the same role as in the usage?

Thanks,
Daniel
