That depends on who is doing the asking and what the needs are.

If it is a human, then probably a GET would be most useful, since
(a) humans tend not to care about the specifics of URI denotation
and semantics and are able to guess about alot of stuff and (b) most
humans wouldn't grok RDF/XML anyway.

If it is a sw agent, then probably an MGET would be most useful,
since (a) sw agents tend to have a hard time understanding
arbitrary web content and (b) most sw agents will probably
grok and benefit far more from the RDF/XML anyway.
