Virtuoso and BPEL

Please I want to understand how Virtuoso implement BPEL. I have searched for materials out there and it seem to be of little or no help.

The response remains the same as in your previous post on BPEL ie How can my .NET client gain access to WS-BPEL functionality in Virtuoso?

What are you trying to achieve here?

WS-BPEL is old functionality that has not been used for a while due to lack of general interest circa 2022

Please If WS-BPEL is an old functionality what is the alternative now?
