Inter-cloud Document Exchange and Collaboration

Interoperability is of historically observable importance (e.g. email). In defining Inter-cloud interoperability models, issues of identity are central and unavoidable. In particular, businesses trading with one another want to be able to collaborate and exchange business documents between their respective systems, which are increasingly Cloud-based. Such exchanges are already possible in many cases today, but typically require relatively high-cost and non-standardized setup processes. Thus Business entities trading with one another require seamless establishment of new electronic trading relationships via their existing Cloud business and commerce systems. In particular, it should be possible to set up the identities and relationships required on the various Cloud systems with zero or minimal user intervention.
