Does anyone know a workflow system based on Zend (or php), which is open source and can be integrated in a project? What do I understand as workflow system:
- User starts a workflow through submitting some start parameter (e.g. SOAP/HTML request)
- Zend runs the workflow in the background (on high server load the operations are lined up in a queue)
- Workflow may be build out of several modules/actions e.g. export xml > create pdf > send pdf to user > send email (Backend)
- User sees current status of the running workflow online and gets the result as soon as finished through ajax requests to the server. (User Interface)
- Admin has a overview of general running workflows (Admin Interface)
Thanks for your hints!
