Chapter 4. BPMN 2.0 Notation
4.1. Business Process Model and Notation (BPMN) 2.0 Specification
The Business Process Model and Notation (BPMN) 2.0 specification defines a standard for graphically representing a business process; it includes execution semantics for the defined elements and an XML format to store and share process definitions.
The table below shows the supported elements of the BPMN 2.0 specification and includes some additional elements and attributes.
