IMO, the statement:
http://viaf.org/viaf/64055977/ skos:note “He smelled very bad”
contains no provenance information about the _statement_. It is
dangerous to infer any from the subject URI (although one might infer
something about the provenance of the subject URI itself). If people
interpret that wrongly as Kevin mentions, that seems like an education
Now, perhaps if I downloaded that statement as LOD from
http://viaf.org/viaf/64055977/ then I might reasonably infer something
about provenance (perhaps that OCLC asserted, approved or collected the
statement; to be specific one would need out-of-band knowledge of OCLC
and that dataset).
If one really cares about the expressing the provenance then it should
be made explicit and systems will need to keep track of it. This could
involve recording where things came from in "identified datasets" as
Jeff Young suggests (separate branch of the thread) or more heavyweight
methods such as named graphs, nquads etc...
Being able to served LOD from a subject URI does seem like a valid
motivation to mint new URIs that are owl:sameAs existing ones. However,
I don't think that should be conflated with provenance interpretation.
