Tangled Web Services If, like me, you were confused about the business-process segment of the web-services protocol stack, the recent announcement by IBM, Microsoft and BEA of BPEL4WS only made things worse. After reading, asking questions, scratching my head, and reading some more, I think I've got it. (And I'm sure you'll let me know if I haven't.)
Some highlights and explanations:
- XLANG and WSFL are gone, replaced by BPEL4WS.
- The BPMI.ORG stack--supported by a very large number of members, most notably Sun--is based on XML, but predates SOAP. That means it works on top of other protocols, but doesn't take advantage of SOAP's support. The BPEL4WS stack utilizes, and is locked to, SOAP.
Thanks to Dave Wright at Microsoft for clearing my cobwebs, and to Peter Drayton for posting links to the newly-published specs.
