A Coordination System Approach to Software Workflow Process Evolution
Jean-Marc Andreoli, Christer Fernstrom, Jean-Luc Meunier
This paper describes a coordination-based approach to the dynamic evolution of (software) workflow processes.
Our interest is in widely distributed workflow processes, i.e. systems that allow each instance of a process
model to be enacted in a distributed fashion, with different parts of the process being enacted on different
nodes of the system. More specifically, we are interested in the problem of dynamic workflow process evolution
in such a distributed context, where the propagation of changes to all the concerned nodes has to be
performed in an orderly manner. We address the problem of dynamic workflow process evolution from a
coordination system approach, considering the workflow system as a coordination system and the workflow
evolution as a coordinated evolution of the coordination schemes. We illustrate the problem of workflow
evolution in a software engineering context, and describe a method using the reflexive features of our underlying
coordination system to support dynamic workflow process evolution in a distributed workflow system.
