Business Process Model and Notation 2.0 is the result of consensus among Business Process Management (BPM) system vendors. The Object Management Group (OMG) has developed and maintained the BPMN standard since 2004.
The first version of the BPMN specification focused only on graphical notation, and quickly became popular with the business analyst audience. BPMN 1.x defines how constructs such as human tasks, executable scripts, and automated decisions are visualized in a vendor-neutral, standard way. The second version of BPMN extends that focus to include execution semantics, and a common exchange format. Thus, BPMN 2.0 process definition models can be exchanged not only between different graphical editors, but can also be executed as is on any BPMN 2.0-compliant engine, such as the engine embedded in OpenIDM.
Using BPMN 2.0, you can add artifacts describing workflow and business process behavior to OpenIDM for provisioning and other purposes. For example, you can craft the actual artifacts defining business processes and workflow in a text editor, or using a special Eclipse plugin. The Eclipse plugin provides visual design capabilities, simplifying packaging and deployment of the artifact to OpenIDM. See the Activiti BPMN 2.0 Eclipse Plugin documentation for instructions on installing Activiti Eclipse BPMN 2.0 Designer.
Also, read the Activiti User Guide section covering BPMN 2.0 Constructs, which describes in detail the graphical notations and XML representations for events, flows, gateways, tasks, and process constructs.
