This little Play application is a simple prototype how one could define instances of BPMN models. A process instance is an execution path within a BPMN model. For example, XOR gateways are replaced with the pair of executed paths.

yields the following instance, if Task B is invoked during process execution.

Run ./activator run to run the Play! application. On http://localhost:9000/docs/swagger-ui/index.html?url=/docs/swagger.json you will find a little documentation of the API. From start, there is a process with id scanMail available. Ontologies can be found in conf/resources.
