MGET, MPUT and MDELETE are only relevant for URIs which are meaningful
to the HTTP protocol (or any other protocol for which bindings are
defined).

So there will be URIs used in RDF statements which will not be usable
with MGET, etc. because they are not dereferencible via HTTP.

For these cases, the URIQA model also defines a service interface, which
works for any arbitrary URI, but without question, the utility for such
URIs is significantly reduced.

IMO, though, folks should be using http: URIs to denote all resources,
abstract or otherwise, web documents or otherwise, and only use other
URI schemes when absolutely necessary and justified.

URNs, DOIs, and many other strongly promoted URI schemes are simply
unnecessary. One can achieve all the requirements/goals put forth for
such schemes using http: URIs and domain management.

Cheers,

Patrick
