This conversion takes any Visio file by mapping the Visio shapes in your drawing to BPMN shapes. You will experience varying level of success in the mapping depending on the shapes you have used in your drawing. For optimal results, you can use the Trisotech BPMN Modeler for Visio. Once the BPM model has been determined, it is converted to WS-BPEL* 2.0 files with a WSDL file if required.
BPMN shape detection is best guessed from the shapes in your drawing, unless it is part of Trisotech BPMN Modeler for Visio, Microsoft BPMN stencil, Microsoft EPC stencil or ITP Commerce. (The structure of other 3rd party shape vendor is unknown)
Unrecognized shapes are mapped to tasks or sequence flows.
Each page having content is considered to represent one process with the following exceptions:
If a page contains more than one pool with content, then one process by pool is considered.
If matching link event can be found between pages and if those link events are in no pool or in a pool with the same name, then they are considered to be the same process and their parent pool are considered to be the same pool.
Current conversion to WS-BPEL supports only the basic mapping as described in section 14.1 of BPMN 2.0 specification available at http://www.omg.org/spec/BPMN/2.0/.
Every construct that does not have a direct mapping is placed in a Flow and its sequence flows are represented by Links.
One WS-BPEL file is created by BPMN process
If there’s pertinent information in the Visio file, one WSDL file is also created to present implementation details of the whole file.
Process must have one entry point (a start event, an event based gateway or one activity with no incoming sequence flows). If this is not the case, conversion will create an empty activity as an entry point related to every element having no incoming sequence flows.
When an activity has more than one outgoing sequence flows, mapping is done as if the activity was followed by either an inclusive gateway (if there is condition on the outgoing sequence flows) or a parallel gateway (if there is no condition)
When a gateway has many incoming and many outgoing sequence flows, mapping is done as if there was one merging gateway and one diverging gateway of the same type.
Every event and task having no WS-BPEL mapping is transformed into a WS-BPEL Empty activity.
Artifacts, data stores, process data input and data outputs are ignored (They do not have a defined mapping)
