Business-to-business (B2B) exchange of broadcast media files will become increasingly important in the future. This paper outlines requirements for such exchanges, describes a flexible architectural model and proposes the use of an XML document - the "Manifest" - as a means of encapsulating the information involved in an exchange transaction. Examples of the use of the Manifest and potential applications are described, together with possibilities for future work and standardisation.
