A computer language for facilitating communication between web services, where web services may use disparate input and output document formats, and system using same. A Conversation Definition Language (CDL) is extended with transformational information to a Transformational Conversation Definition Language (TCDL). The CDL defines document types, transitions and interactions of a conversation between two or more web services. In a preferred embodiment, the transformational information is a subset of the interaction information. Stylesheets are used to define the semantics of the required transformation and the appropriate stylesheets are identified in the TCDL file. A conversation controller component reads the TCDL files that correspond to a given conversation and utilizes the transformation information, when necessary to transform documents between web services without human intervention.
