If you take the IETF view of URIs then they can be - if you provide the

Using II queries, you could have many things being specified the same -
such as




*providing* your resolver was set up to handle this (ie amazon would
probably provide the authoritative URI resolver for that instance).
The handling of RDF URIs obviously was a cause for debate last time
