Hi,

I think this is one of the important applications of RDF queries - it allows
RDF information to be aggregated, then processed by "ordinary XML" tools -
simple XSLT scripts, etc.

One of the benefits of the XML syntax should be that many things can be done
with RDF without having to have a full RDF framework - there are a lot of XML
tools and development that could be applied to information if a canonical
syntax was available.

On the other hand, rather than suggesting there is a single caonical
approach, I thin what is useful is a simple mechanism for saying how to turn
given RDF into a particular XML schema for processing the bits that are
understood.

For example I am producing some simple Xforms for creating RDF. They work on
an XML instance file, and address it using Xpath - if I could collect a large
dataset and put it into a given syntax I would be able to add information
easily to that collection by using simple xpaths, and know that I was not
going to lose or miss things because of the vagaries of generic RDF
serialisation.

cheers

Charles
