Existing SOA is broken because it is only half-decoupled, it is argument 
or XML based (i.e. RPC) rather than RDF or RDF rich query (RDF, rules, 
remote queries), it is usually synchronous, half-duplex, RPC-styled, and 
layering that may be non-optimal.  Not only is there a tower of babel 
problem to some extent up front, but resulting applications are fragile 
due to procedural back-end coupling.

We have a Knowledge Oriented Architecture (KOA) that is fully decoupled 
(both "front" and "back" side), rule-driven, and RDF metadata and 
knowledge driven.  We have been exploring a number of architectural 
ideas in this area for large clients.  A public version is planned.
