# BPMN Model API

The BPMN model API enables easy extraction of information from an existing process definition, editing an existing process definition or creating a complete new one without manual XML parsing.

Note: Currently the BPMN model API does not support the entire BPMN 2.0 specification.
The list of already supported BPMN 2.0 elements can be found in the source code package [org.camunda.bpm.model.bpmn.instance](https://docs.camunda.org/javadoc/camunda-bpm-platform/7.24/org/camunda/bpm/model/bpmn/instance/package-summary.html).
