MOBILE: A Modular Workflow Model and Architecture

Workflows are characterized by multiple aspects: the functional aspect describes what has to be executed; the behavioral aspect tells when to execute a workflow; the organizational aspect determines agents that have to perform a workflow; the informational aspect defines data flow between workflows. In this paper we present a workflow model which follows this separation into various aspects. The major principle of the workflow model is modularity what is the prerequisite for reusability, extensibility, robustness, and ease of use. Finally, we briefly introduce an architecture of a Workflow Management System which implements the various aspects of the workflow model.
