The Process Virtual Machine is a process kernel designed to support multiple process formalisms by providing a internal formalism in which to define process meta-models; a common process infrastructure to support the definition, instantiation, and enactment of process models expressed in those meta-models; generic support for distribution, persistence, and object management; and independence from the object manager being used to describe the product(s) produced. It is being discussed and designed within the Process Working Group of DARPA’s ProtoTech project.
