I am not sure what the opposite conclusion is that my arguments help  
you reach.

Neither do I. We are both trying to determine where the future is  
going, and reasonable people can easily and rightly agree to disagree  
on that, as it is mostly indeterminate. Guessing the future correctly  
can make a lot of difference in how much money ends up in one's  
pocket :-)

I think at the minimum it is worth considering that SPARQL + an  
ontology can replace a lot of what the complex SOAP web services are  
trying to do. And even simplify the RESTful web services supported by  
Amazon. This is because the Ontology, the query language, and the  
results are beautifully complimentary and fundamentally tied into the  
fundamental web archictecture construct: the URI.
