Hi Graham, If it's the role of provenance-uri, fine, but we have to make sure that the protocol can work with provenance-uris that are not dereferenceable. For instance, we should be able to support "names" of bundles that are a UUID uri. Thanks, Luc On 02/06/2012 08:49 AM, Graham Klyne wrote: > I think it's effectively already there.
