This document specifies a methodology for describing and managing interactions and a format for digital communication between actors in any use case associated with the management of an asset during all life cycle stages.
It provides:
—     a methodology that describes an interaction framework for a use case;
—     an appropriate way to map responsibilities and interactions that provides a process context for information flow;
—     a format in which the interaction framework is specified and executed.
This document is intended to promote secure, verifiable, traceable and high-quality digital IDM communication between actors during all phases of the life cycle of assets, facilitate interoperability between software applications used, and to provide a basis for data- and process-driven information exchange and traceability of communication.
