The Business Process Execution Language (BPEL) is an industry standard language for defining business process models. AquaLogic BPM Studio provides full support BPEL 1.1.
See http://docs.oasis-open.org/wsbpel/2.0/wsbpel-v2.0.html for complete information on the BPEL standard.
AquaLogic BPM Studio provides a BPEL editor Eclipse plugin for creating and editing BPEL processes. See Using the BPEL Process Editor for more information.
The AquaLogic BPM Process Execution Engine can run BPEL processes natively without using extensions. This allows the ALBPM Engine to execute BPEL 1.1 compliant processes created with tools from other vendors.
