[jboss-user] [JBoss jBPM] - Re: Migration from Vitria to jBPM

[tom.baeyens@jboss.com]

there is a very important aspect that you have to keep in mind when converting processes from one language to another.

writing executable business processes (like the vitria processes) is writing software in the sense that you are specifying how the BPMS software should behave.  this is different from analysing and describing how people and systems work together (= the actual business process).  when creating the vitria processes, you have already made a mapping between the actual business processes to executable vitria processes with the constructs available in vitria process language.

it might not always be the best approach to just try and convert the processes automatically.  as the design of the vitria processes was influenced by the available constructs in the vitria language.  

overall, jPDL will be quite flexible to accomodate such a conversion.  but you should take into account that you probably would have created different processes when using jPDL for your initial process langauge.  so practically, the best approach i think is to create a simplistic conversion that doesn't include all the details.  Then take that as a starting point.  This will include a manually revision since there is no standard process language yet.
