Web-oriented architecture (WOA) was coined in 2006 by Nick Gall of Gartner.
[2] Dion Hinchcliffe claims WOA to be: "A core set of Web protocols like HTTP, HTTPS and plain XML, the only real difference between traditional SOA and the concept of WOA is that WOA advocates Representational state transfer (REST), an increasingly popular, powerful, and simple method of leveraging Hypertext Transfer Protocol (HTTP) as a Web service in its own right".
EWOA is defined as the sets of web-based architectural elements, environments, principals and processes.
[5] New applications and websites, such as Google AdSense, Wikipedia and other RESTful services are using WOA, which is gaining attention from the research community and the industry.
Creating these services have become easier using simplified web protocols, e.g. REST and JSON (JavaScript Object Notation).
