Abstract
•
•
•
The facilitation of Process Model Interchange between different modeling
tools and also between modeling tools, process enactment engines and
simulators, has been an objective for at least 15 years. Until recently,
successes in this area have been mostly limited to tools within a single
company. The introduction of portability conformance classes has
promoted successful interchange between the tools of different vendors,
at least for BPMN 1.x diagrams using the XPDL2.1 serialization.
Conformance testing software has been made available to support the
efforts of tool developers in providing interchange functionality.
This work is now being extended to BPMN2.0. New portability
conformance classes are being proposed and conformance testing
capabilities extended to support them. Prototype transforms have been
developed to provide bi-directional translations between BPMN and
XPDL.
In this presentation we discuss the proposed classes. We have focused
on BPMN2.0 Process Diagrams including Collaboration diagrams without
Choreography.

• The original notion of portability conformance classes
was developed by Bruce Silver and Robert Shapiro for
the XPDL 2.1 specification.
• The BPMN 2.0 Process Diagram Conformance classes
proposal was developed by Bruce Silver and modified
by Robert Shapiro.
Proposal for BPMN2.0 Process Diagram
Conformance Classes
• SIMPLE class = constructs supported by “all” BPMN tools,
including basic/high-level tools
– Simpler than the XPDL2.1 SIMPLE
– Get all BPMN tools to interoperate at basic level
• DESCRIPTIVE class = constructs using a basic working set of
BPMN elements
– Familiar from traditional flowcharting
– Describes the typical order of activities and what role or
organizational unit performs or is responsible for each one
– More than the XPDL2.1 SIMPLE but simpler than STANDARD
• ANALYTICAL class = the complete notation
– But omitting technical details such as specification of data structures
and expressions: hence non-executable.
• COMPLETE class = everything
