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.
