Enterprise Payment Bus - Open Source Project

The "Enterprise Payment Bus - Open Source Project" project started as an initiative in the Summer of 2005. The idea was launched by Ivan Mitrovic and Bart Cant and was intended to create a new Payment Workflow taking advantage of open source technologies and standard messaging formats. This blog will feature some of the new updates of the enterprise payment bus. I hope it will encourage any payment professional to participate in this exciting new open source project. Bart Cant

Intro to WS-BPEL

Before we dive into some key aspects of the Enterprise Payment Bus, I like to share with you some more information on WS-BPEL.

The OASIS WS-BPEL Technical Committee approved the WS-BPEL 2.0 specification on 1/31/2007. The official Committee Spec Release Candidate can be download from http://www.oasis-open.org/committees/download.php/22036/wsbpel-specification-draft%20candidate%20CD%20Jan%2025%2007.pdf.
An interesting article about the Goals of the WS_BPEL 2.0 specification can be found at http://xml.coverpages.org/BPEL4WS-DesignGoals.pd f

WS-BPEL 2.0 is a major component of the Enterprise Payment Bus:

WS-BPEL is build on compatible Web services standards

WS-BPEL is an XML based language

WS-BPEL will be used to define the Payment Business Processes that interact with external Payment System entities through Web service operations

WS-BPEL will be used to define a set of Web service orchestration concepts for the Payment work flow that are meant to be used in common by both the external (abstract) and internal(executable) views of a payment business process.

WS-BPEL will be used to define a long-running Payment transaction model that is based on proven techniques like compensation actions and scoping to support failure recovery for parts of the long-running Payment business process.
