Dear all,

I am trying to establish whether this question requires clarifications 
in our documents or not.

Which IDs are we referring to here? Bundle IDs or IDs of 
entities/agents/etc asserted in bundles?
I assume it's entity/agent/etc IDs.

I believe that both prov-dm and prov-constraints are silent about how to 
interpret a given identifier
used in two different bundles.

For instance, we can write:

bundle b1
   entity(id)
endBundle

and

bundle b2
    activity(id)
endBundle

This is valid provenance (according to prov-constraints). It is not 
required explicitly by prov-dm/prov-constraints
that the identifier/uri id denotes the same resource in both bundles.  
But isn't this a principle automatically
"inherited" from the Web architecture?

Thanks,
Luc
