The Business Process Execution Language (BPEL) is an emerging industry standard for achieving a degree of interoperability among business rules engines. The original specification, known as BPEL4WS (Business Process Execution Language for Web Services), was published in August 2002.
See bpel.xml.org and www.oasis-open.org for more information on this specification, sometimes called WS-BPEL.
PRPC supports both connectors and services for BPEL. These operate in conjunction with SOAP connectors and services to interconnect a flow with an external business process.
You can convert an XML file representing a BPEL process rule into a similar flow automatically using the rule harvest wizard.
Conversely, you can create a BPEL representation of a flow directly from the Design tab of the Flow form.
