Cúram workflows can inter-operate with other workflow systems through support for specific aspects of the Oasis group's Business Process Execution Language (BPEL) standard. BPEL processes can enact Cúram workflow processes and be notified when the process completes.
The Cúram workflow engine is not intended to be a fully fledged BPEL orchestration engine. Instead the Cúram workflows should be able to participate in BPEL orchestrated processes. This is done by providing functionality to expose Cúram workflow processes as web services that can be invoked from BPEL process partner links.
