A list of publicly available Web services can be found http://www.xmethods.com/, including a stock-quote service, a traffic-report service, and a weather service.
Each service is independent, reusable, and performs a distinct task. These services can be linked together across or within enterprises using XML. You can stack services like toy blocks, which allows you to build applications from Web services quickly, borrowing blocks from UDDI registries when you need them.
