I can see the enormous interest in having a text-based format for
exchanging object-oriented data. But can't this be done with a good
object-oriented XML schema language, of the which the current W3C seems
to be a very good start? I read Tim's paper on, and he argues
against the use of XML (without an additional syntax) for representing
metadata with two arguments, both based on scalability. But if metadata
are attached in a separate document, as RDF metadata would presumably
be, they could expressed just as concisely (and probably more so) by
using an XML instance based on a simple (but extensible) XML schema. The
latter would be preferably because am extensible schema language is an
important tool in its own right.
