[jbpm-dev] [Design of JBoss jBPM] - Re: Implementation of XPDL in jBPM

[kukeltje]

Sebastian,

As Bernd pointed out,XPDL was so extensible that on a high level you had a standard, but seamlessly migrating from one vendors execution environment to another was almost impossible. That took quite an amount of manual labour (hearsay, no personal experience, so someone may correct me) due to all proprietary the extensions. 

Waiting for BPMN 2.0 and/or XPDL 2.2 (and the relation between the two: https://admin.acrobat.com/_a925169516/p30857824/)  would be better if a standard and interoperability is important.

Regarding Bonita and the PVM, the relation is simple. Bonita (from Objectweb (=Bull, France Telecom and Inria)) was an existing XPDL based system with a proprietary 'core'. JBoss and Bull decided to work together on certain projects and the PVM was one of them. So, the new Bonita is based on the PVM, but still their product not one from JBoss. Maybe in the future the cooperation will become even closer if BPMN2.0/XPDL2.2 comes in the picuture.
