Event-Driven Process Chains (EPC)
Developed in the context of the ARIS Toolset, event-driven process chains (EPC) were long the most used process modeling language.

Oryx supports an extended version of EPCs including constructs for control flow, data flow and resource allocation. On top of that, Oryx comes with syntax checking capabilities.
You want to switch to BPMN in your organization? No problem, Oryx offers you functionality to convert your EPCs to BPMN.
