Document Summary

Itm706: week 9/lecture 8 business process modelling with bpmn 2. 0. A modeling language consists of three parts: syntax, semantics, and notation. The syntax = provides a set of modeling elements and a set of rules to govern how these elements can be combined. The semantics = bind the syntactical elements and their textual descriptions to a precise meaning. The notation = defines a set of graphical symbols for the visualisation of elements. The bpmn syntax includes activities, events, gateways, and sequence flows. An example of syntactical rule is that start events only have outgoing sequence flows whereas end events only have incoming sequence flows. The bpmn semantics describes which kind of behavior is represented by the various elements. This relates to the question how the elements can be executed in terms of token flow. For example, an and-join has to wait for all incoming branches to complete before it can pass control to its outgoing branch.
