This document discusses Business Process Model and Notation (BPMN), a standard for modeling business processes. It aims to allow business process models created in different tools to be interoperable. The document provides links to information on BPMN, an example diagram, the BPMN Interoperability Challenge to address lack of interoperability, and lists vendors that support the BPMN Model Interchange Format which enables process exchange between tools using BPMN. It also includes contact information for a BPMN MIWG member.
