The ProcessWall: A Process State Server Approach to Process Programming 
Dennis Heimbigner 

The ProcessWall is a process state server providing storage for process
states plus operations for defining and manipulating the structure of
those states. It separates the state of a software process from any
program for constructing that state. Instead, client programs implement
the processes for operating on the process state. This approach has a
number of potential benefits such as support for process formalism
interoperability, support for multiple process languages, low-cost
retro-fitting of process into existing environments, and support for
long-term execution of processes. The process server interface provides
descriptive mechanisms for representing process state as well as product
state. A classification of client programs is provided to show how the
state server can be used in a variety of ways.
