The Web Services Platform
So what is the web service platform? The basic platform is XML plus HTTP. HTTP is a ubiquitous protocol, running practically everywhere on the Internet.

UDDI registries describe numerous aspects of web services, including the binding details of the service. WSDL fits into the subset of a UDDI service
