Freeflow

Abstract

In order to understand some problems associated with workflow, we set out an analysis of workflow systems, identifying a number of basic issues in the underlying technology.This points to the conflation of temporal and dependency information as the source of a number of these problems.We describe Freeflow, a prototype which addresses these problems using a variety of technical innovations, including a rich constraint-based process modelling formalism, and the use of declarative dependency relationships.Its focus is on mediation between process "and action, rather than the enactment of a process.We outline the system and its design principles, and illustrate the features of our approach with examples from ongoing work.
