Green Pages (UDDI)

From Wikipedia, the free encyclopedia

Green Pages are one of the three main components of UDDI - the protocol used to discover Web Services (the other two components being White Pages and Yellow pages).

Green pages are used to describe how to access a Web Service, with information on the service bindings. Some of the information is related to the Web Service - such as the address of the service and the parameters, and references to specifications of interfaces^[1]. Other information is not related directly to the Web Service - this includes e-mail, FTP, CORBA and telephone details for the service. Because a Web Service may have multiple bindings (as defined in it's WSDL description), a service may have multiple Green Pages, as each binding will need to be accessed differently.
