Re: PROV-ISSUE-32: Bob definition [Conceptual Model]

Jim,

Sorry, but this discussion seems to be ungrounded.  Can we refer
to the draft specification [1], where we try to explain what form of 
representation/assertion
we have:

/PIL is a language by which representations of the world can be 
expressed using terms that are drawn from a controlled vocabulary. These 
representations are relative to an asserter, and in that sense 
constitute assertions about the world. Different asserters will normally 
contribute different representations, and no attempt is made to define a 
notion of consistency of such different sets of assertions. The language 
provides the means to associate attribution to assertions./

Thanks,
Luc
