Re: ZDNet Schema article, and hiding complexity within user-friendlyproducts

[Tony Presti <apresti@bellsouth.net>]

I remember those G3 and G4 spec issues when attempting imagery integration for
Xray film....

And you are correct, Len - the issue IS XML approach with RDF schema.  XML and
associated schemata approaches can only work within limited domain constructs
for semantic applications.  The addition of RDF schemata to XML apps seems to
hold much more promise for reduction of computational intensity in large-scale
or (dare I say it?) unbounded semantic web knowledge assembly.
