Since the motivation for bundles (and to some extent contextualization) seems to be provenance of provenance", it's unsurprising that object vs meta-level issues are appearing. It may be inevitable that people want to do this, but it's up to us to decide whether to codify it. Is there a body of current practice? Do a lot of existing vocabularies allow something like this, and are we picking a popular design? Or are we making something up as we go? Concretely, what in the example breaks if we just say specializatonOf(tool:Bob-2011-11-16, ex:Bob)? --James On Jun 28, 2012, at 3:26 AM, Luc Moreau wrote: > Hi James, > > I was wondering about your notion of "normal attributes" and the notion of "underlying Thing". > The use case we discuss, where a piece of software (rating tool) reads some provenance and, > with application-specific reasoning, rates entities blurs the distinction. > > In the example: > > agent(tool:Bob-2011-11-16, [perf:rating="good"]) // this is the rated agent > specializationOf(tool:Bob-2011-11-16, ex:Bob, ex:run1) // or contextualizationOf > > The rated agent tool:Bob-2011-11-16 is generated after the tool has processed the contents of ex:run1. > In that case, the syntax, by this I mean the bundle, is part of the semantics. > > Isn't this inevitable with "online uses" of provenance, where processing of provenance helps > makes decisions in the application domain? > > Luc > > > On 06/28/2012 04:35 AM, James Cheney wrote: >> >> I don't view the property "being described in bundle b" as the same kind of attribute as normal attributes - to me, attributes describe properties of the underlying Thing, in the semantics, not properties of the entities describing the Thing in the syntax.
