Hi,

My 5 cent (of a Euro :^) about this topic:

I already proposed such an approach a year ago at GCA's Metastructures 99,
Montreal. The ISO WG call them TM templates. A template (or application profile
or schema) contains all ontology declarations, transitivity information,
type hierarchy information, explicit inference rules, and validation
constraints.

Last week I presented the final results at GCA's Extreme Markup
Languages 2000, Montreal. The concept is based on PSIs (Public 
Subject Identifiers) which have to be publicly registered by ISO or 
OASIS or whoever. This registration is everything what is needed,
no standard has to be changed, but TM tools can refer to the PSIs and
support their semantic which is clearly defined together with the
registration. This method allows definiton of various
application dependent profiles (e.g. knowledge representation,
subject classification, and other use cases). 

My paper is in the Extreme ML proceedings and the appropriate
XTM WG should have access to it. If requested I can upload a 
PDF to the egroups server.

Having such technique at hand knowledge representation can be done
using TMs. Reading Sowa's book will convince you (he is talking about
conceptual graphs which could be expressed as TMs without any problems).

Regards,
--Holger
