I want to respond to what you are saying to each other, as I have 
been following this discussion with interest.

I am new to RDF, which I am taking to with enthusiasm as it is a 
provides a solution to a number of my problems with definitions 
associated with data.  I am interested in computer generated 
algebra, and became aware some time ago of content MathML as a 
means for encoding results.  I also want to attach to the algebra 
when the result was computed and what its meaning is, things 
which can be done with e.g. Dublin Core within RDF without me 
having to reinvent the wheel. So although I am using XML I am not 
yet committed to any particular XML tools.

Instead I have been planning to use E4Graph 
( to store my data, with output as 
XML as a means of exchange.  My concern has been to make sure 
that the RDF/XML output from my programs can be read into 
another program as good RDF/XML and that has lead me to 
propose to Jacob Levy (who develops E4Graph) a few small 
changes and options for E4Graph.  I have now done that.

So, please don't give up on RDF/XML, as it provides a means of 
exchange between computer programs for data which may be too 
complex for a human to want to read.
