UDDI

WSDL

SOAP

UDDI is a protocol for describing Web services components that allows businesses to register with an Internet directory

They can advertise their services and companies can find each other and carry out transactions over the Web.

WSDL is the proposed standard for describing a Web service.

WSDL is built around an XML-based service Interface Definition Language that defines both the service interface and the implementation details.

WSDL details - from UDDI entries(SOAP messages needed to use a particular Web service.)

Communication involving UDDI uses SOAP to package UDDI requests and replies to a Web services repository.

SOAP is a protocol for communicating with a UDDI service

The advantage of SOAP is that it can use universal HTTP to make a request and to receive a response.

SOAP requests and responses use XML not only to target the remote method but to package any data that is required by the method.
