One alternative serialization that I am very interested in is XML topic
maps.  Unlike RDF, the XTM model has a coherent approach to provenence --
something that is probably on the necessary growth path for the RDF data
model.

So I also strongly favor the ability to negotiation for any interchange
representation using its Internet MIME Type.

That really only makes sense if the non-XML serializations are common.
Otherwise, the set up client/server has a dependency in assuming some format
is available.  I suppose use(abuse? not sur eit is correct use) of OPTIONS
is possible.

We would, I presume, require that at least RDF/XML is supported as a
serialization format for reasons of maximum interoperability.  Where
additional features (e.g. named graphs) are needed then fine.  It's
encouraging the alternative serializations of core RDF where I don't
understand the need for a requirement.

Generally, I don't expect people to look at the results of a DAWG query
directly - the output is consumed by some client-side application - so I
don't put much weight on the need for alternative serializations.
