This article from cnetnews.com states: Web-oriented architecture (WOA), a descriptive term for a subset of service- oriented architecture (SOA), has recently arisen as the next buzz-phrase to help further confuse the IT architect. So what is it? The article explains that WOA is an implementation of SOA that utilizes representational state transfer resources that permit data and services to be utilized through a uniform resource identifier. Another explanation comes from Nick Gall from Gartner:
WOA is an architectural style that is a substyle of SOA based on the architecture of the www with the following additional constraints: globally linked, decentralized, and uniform intermediary processing of application state via self-describing messages.
