UDDI is a platform-independent framework that allows businesses to publish details about their web services and discover information about other businesses and their services. It provides a directory for storing metadata about web services in a standardized format. UDDI is built on XML, HTTP, SOAP and other common web standards. It allows businesses to register information about themselves, their services, and technical details about how to access those services to facilitate easier integration between businesses over the web.
