that have already been defined. Classes and properties (the metamodel) are the
guidelines for the design in order to define the model, that is, to insert the instance
of the model.
We develop an ontological metamodel where classes and properties are defined in
order to express all BPMN primitives. In our ontological BPMN metamodel we
define not only the main primitives but also properties of each of them.
In our approach we develop BPMN metamodel following different steps:
??? Analysis of BPMN specification in order to extract the main concept: each
concept is defined as ontological class.
??? Analysis of BPMN in order to extract details of each concept defined in the
previous step: each concept is modeled as ontological subclasses tied to the
main classes.
??? Analysis of BPMN in order to extract concepts that support the concept defined
in the previous steps. Each concept is defined as ontological class.
??? Analysis of BPMN in order to extract properties that allow us to provide a
semantic to concepts previously defined.
