Transformations as web services

Abstract

A transformation Web service description describes a Web service capable of receiving a message having a format compatible with a format of a message associated with a first Web service and transforming the message to a transformed message compatible with an input message format for a second Web service. The Web service description may be expressed in the Web services Description Language (WSDL). The Web service description includes a transformation description describing the transformation to be performed. The transformation description may be a programming language and platform neutral description such as an eXtensible Stylesheet Language Transform (XSLT) stylesheet and may be included within a transformer binding which extends WSDL. To support transformations involving multiple inputs and outputs, multiple input and/or output messages may be aggregated into a single multi-part input or output message, where each part has an attribute which references one of the multiple messages to be aggregated.
