Mapping BPMN 2.0 constructs to IBM Business Process Manager

You can import elements from the IBM® WebSphere® Business Modeler into IBM Business Process Manager, using the Business Process Model and Notation (BPMN) Version 2.0 file format.

The following table shows the mapping between elements in the Business Process Model and Notation (BPMN) Version 2.0 file format and their equivalent IBM Business Process Manager objects or properties, after import. If an element is not included in the table, the element is not imported. The top-level library elements are in boldface type. The elements that are not in boldface type and are listed under a top-level library element, are subordinate elements within them.

Table 1. Mapping between BPMN constructs and IBM Business Process Manager elements after import
BPMN Construct	IBM Business Process Manager element	Comments
Item Definition	Business Object
Message- Not referencing an Item Definition	Business Object - without a structure
Resource	Participant Group
Global Task	Integration Service or Advanced Integration Service	Element selection depends on your choice in the procedure described in Moving business processes from WebSphere® Business Modeler to Process Designer or Importing BPMN models.
Global User Task	Human Service
Global Rule Task	Decision Service
Interface - with / without a backing WSDL	Integration Service or Advanced Integration Service	A Service is generated for each operation in the interface. Element selection depends on your choice in the procedure described in Moving business processes from WebSphere® Business Modeler to Process Designer or Importing BPMN models.
Process	Business Process Diagram
Task	Activity	The following applies: If the task has performers, the Activity has a User Task implementation and references a Human Service. If the task has no performers, the activity has a System Task implementation and references an Integration Service or a System Service. If an incoming service is, for example, a web service that contains data to set up a binding, it is reflected in the business service. Additional steps are needed to perform this invocation. See Wiring a Web Service Integration Component using IBM Process Designer for more information.
Human Task	User Task referencing a Human Service
Business Rules Task	Decision Task referencing a Decision Service
Service Task - To an operation with/without a backing WSDL	Activity - with a System Task implementation, referencing an Integration Service
Receive Task	Intermediate Message Event
Script Task	Activity - with a Javascript implementation
All other Task types	Activity
Subprocess	Activity with a Subprocess type	Only a single None Start Event is allowed. Other start event types are collapsed into the single None Start Event.
Event Subprocess	Activity with an Event Subprocess type	Only a single Error, Timer, or Message Start Event is allowed. If there is more than one, only the first is used. Other start event types are converted to an Error Start Event.
Call Activity referencing a Process	Activity	The Activity references a Business Process Diagram.
Call Activity referencing a Global Task	Activity - with a Service (task) implementation, referencing an Integration Service	The Activity references a Service
Exclusive Gateway	Exclusive Gateway
Inclusive Gateway	Inclusive Gateway
Parallel Gateway	Parallel Gateway
Event-based Gateway	Activity - with Message Boundary Events	The Message Catch Events that followed the Event-based Gateway are converted to Message Boundary Events attached to the activity
None Start Event	Start Event	Only a single None Start event is allowed. If there is more than one, only one will be created.
Message Start Event	Message Start Event
Timer Start Event	Timer Start Event
Error Start Event	Error Start Event
All other start Event types	Start Event
End Event	End Event
Error End Event	Error End Event
Message End Event	Message End Event
Terminate End Event	Terminate End Event
All other End Event types	Activity followed by an End Event
Intermediate Catch Message Event	Intermediate Message Event (Receiving)
Intermediate Catch Timer Event	Intermediate Timer Event
Intermediate Catch Link Event	Sequence Flow
All other Intermediate Catch Events	Activity
Intermediate Throw Message Event	Intermediate Message Event (Sending)
Intermediate Throw Events	Activity
Boundary Error Event	Error Event attached to an Activity
Boundary Message Event	Message Event attached to an Activity
Boundary Timer Event	Timer Event attached to an Activity
Sequence Flow	Sequence Flow
Text Annotation	Note
Data Object	Private Process Variable
Process Data Input	Process Input
Process Data Ouput	Process Output
Input Data Association	Data mapping inside an Activity.	From a process variable or input to a service input or process input.
Output Data Association	Data mapping inside an Activity.	From a service output or process output to a process variable or output.
