What is SCXML?

SCXML is an XML-based language for describing statecharts: state machines with hierarchy, concurrency, events, and executable actions. It is useful for modeling application behavior, workflows, interaction logic, and other systems whose behavior changes in response to events.

This site collects practical resources for learning SCXML and using it with SCION. Later, we will add more SCXML examples. One day, we will release SCION Studio as well.
