Imixs-Workflow supports the BPMN 2.0 standard and simplifies the way to design and execute business logic. It is a free modeling tool which, in order of becoming a powerful workflow engine, uses the full advantage of all the capabilities of the BPMN standard.
It enhances the Eclipse BPMN2 Modeling Framework with the aspects of a human based workflow model executable on the Imixs-Workflow Engine. BPMN was initially designed to describe a business process without all the technical details of a software system and this diagram easy to understand and a good starting point to talk about a business process with technician as also with management people.
There are a lot of technical aspects which are typical to a workflow management system, besides the general description of a business process with BPMN. For example users can distribute a task automatically by email to different users or open issues can be organized in a user friendly task list - like messages in an email in-box, because the Workflow Management System controls each task from the starting point until it is finished.
This means that workflow engine can control the life-cycle of a business process. The Imixs-BPMN Task Element is an extension to the BPMN Task Element and can be used to describe a Workflow Task inside a workflow model. This Element has a custom set of properties used to describe the status of a process instance controlled by the Imixs-Workflow engine and it represents an extension to the BPMN CatchEvent which can be used for describing a transition from one Imixs-Workflow Task into another.
