WWWorkflow is a language-driven, data-base-mediated, web-based process mediation system. WWWorkflow leverages on intranet applications and existing information infrastructure services, making it possible to add workflow management features to preexisting information management systems, without the need for significant modifications of those systems. A distinctive feature of WWWorkflow is the careful separation of process mediation from product-data management. WWWorkflow supports many types of workflow and is not focused on any single information structure. WWWorkflow components include a web-based user front-end, a workflow "engine," a workflow data base, and a graphical workflow editor and authoring tool. The web-based user front-end of WWWorkflow allows any user with a web browser to interact with the system. The workflow "engine" contains a workflow language interpreter, as well as an event-driven process mediation service. The workflow data base provides persistence of workflows underway as well as status and historical information for complete reporting. The graphical workflow editor and authoring tool provides both capabilities to produce and edit workflow procedures.
