Do you mean XML or RDF in particular?  I was referring to XML, which
is coming along very well -- see
is that we stop worrying about the low-level lexical details of markup
and start worrying about higher-level issues like object exchange
(RDF, XMI, or what-have-you).

Because that's the nature of information exchange.  Any
fully-normalized information is going to be hard to read, because
you're going to have to jump around following the links; any
fully-denormalized information is going to be hard to process.

I don't know if RDF should have tried to deal with both situations in
the same spec (probably not), but switching low-level syntax from tags
to parentheses is hardly going to affect the fundamental problem.
Machines and people eat information differently.

All the best,
