Stardust/Enhancing and Embedding Stardust/Browser Modeler/BPMN Mapping
This page documents how Stardust relates to and supports BPMN 2.0 with respect to a) modeling support (browser modeler) and b) engine support (i.e. transformation of BPMN 2.0 XML into the Stardust object model).
The description targets the graphical BPMN elements as well as several supporting elements basically not visible in a process model.
The following aspects/items are provided for each (if applicable):
Spec: a hint on where to find a description in the BPMN 2.0 specification (i.e. class model and attributes/relations)
BPMN Modelling Conformance Subclasses: the conformance subclasses to which the element belongs (cp. chapter 2 of the BPMN 2.0 specification)
Modeler support: whether/how the browser modeler supports the corresponding element
Stardust Support: extent of execution support / limitations.
Mapping Description: which stardust element or configuration/construct corresponds to the BPMN element (i.e. how to reach the intended behaviour or functionality)
Transformation: current state of transformation
Testmodel(s): link(s) to BPMN XML testmodels (with Stardust extensions, if available) with corresponding elements
see also: link(s) to related or supporting elements providing more
Attributes: usage / mapping of BPMN element attributes. In general, only the element-specific attributes are considered (not inherited from upper classes).
Related Elements: usage / mapping of BPMN element model associations
Extension Elements/Attributes: extensions to BPMN for Stardust specific information and links to object model classes, if available (note '::<super>' is used to indicate a superclass)
Specific types: list of more specific elements / subclasses not yet described separately

Callable Elements
BPMN process
Spec: OMG p.146f
Stardust Support: full
Mapping Description: BPMN processes correspond to processes in Stardust.
Transformation: partial (related elements missing)
Testmodel(s): e.g. CollapsedSubprocess.bpmn (any testmodel contains at least one process).
see also: callActivity
Related Elements
- Auditing: tbd
- Monitoring: tbd
- Property: Stardust Variable (Data)
- Resource role: tbd
- Artifact: tbd
- CorrelationSubscription: tbd
- Interface: tbd
BPMN globalTask
Spec: OMG p.187f
BPMN Modelling Conformance Subclasses: -
Stardust Support: partial
Mapping Description: BPMN Global Tasks are not directly available in Stardust, however, a process with a corresponding 'global task' can be generated.
Transformation: TODO
Task call: see callActivity
Related Elements
- Property: Stardust Variable (Data)
- Resource role: tbd
- Interface: tbd
Specific types
- globalUserTask: see userTask
- globalManualTask: see manualTask
- globalScriptTask: see scriptTask
- globalBusinessRuleTask: see businessRuleTask
Activities / Subprocesses
Common Activity Extensions (Subprocess, Task etc.):
- TStardustActivity.java (::TStardustCommon TStardustCommon.java)
- EventHandlers
- HibernateOnCreation
BPMN subProcess
Spec: OMG p.173f
BPMN Modelling Conformance Subclasses: Executable (expanded) / Descriptive / Analytic
Stardust Support: partial (collapsed subprocesses)
Mapping Description: BPMN Sub-Processes correspond to Stardust Sub-Processes. In Stardust, subprocess-activities call a process whilst BPMN subprocesses contain their process elements (i.e. they are flow element containers). However, by specifying the called process in stardust as 'synchronous with shared data', the behaviour and even data visibility are similar to BPMN.
Transformation: available
Testmodel(s): CollapsedSubprocess.bpmn
Related Elements
Specific types
- AdHocSubprocess: tbd
- EventSubprocess: tbd
BPMN callActivity
- Activity
Spec: OMG p.183f,
BPMN Modelling Conformance Subclasses: Executable / Descriptive / Analytic
Stardust Support: partial (no direct call of GlobalTask)
Mapping Description: Call Activities correspond to the Stardust Subprocess Activity, whereas the configuration differs from a default Subprocess call (cp. BPMN Sub-Process) with respect to the data visibility (i.e. separate data).
Transformation: todo
Testmodel(s): todo .bpmn .bpmn
Attributes
- none
Related Elements
- calledElement [CallableElement]
Extension Elements/Attributes
- tbd (::StardustActivity)
Process Call
Mapping Description: The Stardust Sub-process Activity synchronously calls a process with separate data (i.e. process parameters / input-/output-paths are used, mapped to BPMN Process DataInput/DataOutput elements).
Transformation: todo
GlobalTask Call
Mapping Description: Global tasks are transformed to Stardust Processes containing an Activity that corresponds to the GlobalTask (see globalTask). The call then works similar to Process Call.
Transformation: todo
Tasks
BPMN Task (Abstract / None)
Spec: OMG p.156f
BPMN Modelling Conformance Subclasses: Descriptive / Analytic

Services
BPMN Interface
Spec: OMG p.104f,
BPMN Modelling Conformance Subclasses: -
Stardust Support: based on extensions
Mapping Description: "An Interface defines a set of operations that are implemented by Services" (OMG p.104). Therefore the Interface element is used as container (see extension element StardustInterfaceType below) for the Stardust application specification. As Stardust has a variable concept for different kinds of applications (including a concept of 'accesspoints' e.g. exceeding the interface exposed by WSDL operations), the extension bases on the internal Stardust Object model.
Transformation: available
Testmodel(s): WebService Task: ServiceTaskWebServiceApp.bpmn, Interactive UserTask: UserTaskWebApp.bpmn, Message Events MessageEvents.bpmn
Attributes
- name: Application Name
Related Elements
- operations [Operation]: only used to reference from Activities
- callableElements[CallableElement]: not used
- implementationRef [Element]: dummy usage - references the nested extension element (StardustApplicationType)

Data
BPMN dataObject
Spec: OMG p.205
BPMN Modelling Conformance Subclasses: Executable / Descriptive / Analytic

Related Elements none (see Item Aware Element)
Extension Elements/Attributes none
BPMN dataAssociation
Spec: OMG p.221
BPMN Modelling Conformance Subclasses: Executable / Descriptive / Analytic
Stardust Support: partial (no transformation)
Mapping Description: Stardust defines dataflows through input and outputs of activities (data mapping). In addition, these mappings have a data-path to map the source (part) with the target (part). Thus, data associations are interpreted as such mappings, using the associations's assignment for data paths (and application paths).
Transformation: available
Testmodel(s): Basic Dataflows: DataObjectFlow.bpmn and SimpleTypeDataFlow.bpmn, Dataflows with application access-points/application paths: ServiceTaskWebServiceApp.bpmn and UserTaskWebApp.bpmn
Attributes none (::baseElement)
Related Elements
- transformation[Expression]: data path, if no assignment is defined
- assignment[Assignment]: depending on the association direction (input/output) the assignment-from/to are mapped to data path or application path
- sourceRef[ItemAwareElement]: data object (not used for dataOutputAssociations, as the data mapping belongs to the activity whilst BPMN has a data input element on the activity)
- targetRef[ItemAwareElement]: data object (not used for dataInputAssociations, as the data mapping belongs to the activity whilst BPMN has a data input element on the activity)
Extension Elements/Attributes none (see Assignment)
BPMN Assignment
