Thanks for the URL.  Bob D adds further support for the above point.
In particular, the "sweet spot" of XML has always been in various
methods of formatting and publishing humanly readable documents.    (04)

A related application is EDI, which evolved from formats read by
humans to proprietary computerized forms.  The mapping to XML
provided an open standard for formatting information whose
semantics was stated in documentation written by and for humans.
That's within the scope of the *ML kinds of applications.    (05)

But RDF and OWL were designed to represent logics that had been
stated in formally defined notations long before computers were
invented.  Theorem provers for those notations had been running
since the 1960s.  Notations for storing and transmitting those
logics had been used for decades.  KIF and KQML were developed
and used as proposed standards when the WWW was in its infancy.    (06)

Replacing that well established technology with a notation
designed for electronic publishing was a huge step backwards.    (07)

Yes, but those URIs just provide an alternate access method for
finding the collection of very informal messages.    (010)
