Running customized (non-BPMN) process definitations with Activiti

Respected Activiti Experts,We are evaluating Activiti as a process engine to replace our existing home grown work flow engine. We are quite impressed by the capabilities of Activiti especially related to multi tenancy and REST WS.However, one of the biggest challenge (and probably blocker) to adopt

If your custom workflow definition is XML-like, maybe you can build a XSLT that takes your custom process definition and convert it to BPMN.

That's one option that we are exploring. However, for that we would need the mapping of our custom constructs to the BPMN 2.0 constructs. Is there any place from where I can get the schema (XSD) for the BPMN 2.0 process definitions.

Also any thoughts about available hooks in Activiti to run the custom templates.

Activiti is build to run BPMN, so it won't run custom templates. In the activiti-bpmn-converter module in Github you can find the BPMN XSD. Does your custom template contain a lot of different constructs or do they need to be mapped to service tasks primarily?

Best regards,

Thanks Tijs. Our custom templates have both: different (that is custom) constructs and the Java Classes(i suppose these can be mapped to service tasks)

I would try to map as much as possible to service tasks (stuff like user tasks and such are technically also service task implementations), and then write a converter from your custom element -> the service tasks.
