BPMN Structure
- Srinivasa Vellanki
BPMN file represents the Workflow defined/specified by the designer using Workflow Designer tool in SDC.
Sample BPMN file
Designer is able to define
Workflow
Inputs and Outputs of Workflow
Manage Activities of Workflow
Establish dependencies between Activities in a Workflow
Map Inputs and Outputs of Workflow/Activity to Inputs and Outputs of an Activity
Workflow
SDC Field | BPMN Field | XML attribute/element | Notes | |
|---|---|---|---|---|
| 1 | workflow.versionId | process.id | attribute |
|
| 2 | workflow.name | process.name | attribute | |
| 3 | workflow.description |
| Where do we map description to? |
Inputs and Outputs of Workflow
SDC Field | BPMN Field | XML attribute/element | Notes | |
|---|---|---|---|---|
| 1 |
| process.dataInput.id |
| ? |
| 2 | workflow.input.name | process.dataInput.name | attribute | |
| 3 |
| process.inputSet.dataInputRefs |
|
|
| 4 |
| process.dataOutput.id |
| ? |
| 5 | workflow.output.name | process.dataOutput.name | attribute | |
| 6 | process.outputSet.dataOutputRefs |
Manage Activities of Workflow
Activities are represented in BPMN as ServiceTask.
SDC Field | BPMN Field | XML attribute/element | Notes | |
|---|---|---|---|---|
| 1 | id | serviceTask.id | attribute | ? |
| 2 | name | serviceTask.name | attribute |
|
| 3 |
| serviceTask.class | attribute | Class is a constant configurable in SDC |
Establish dependencies between Activities in a Workflow
BPMN Field | XML attribute/element | Notes | |
|---|---|---|---|
| 1 | sequenceFlow.id | attribute | Identifier of sequence flow generated on creation |
| 2 | sequenceFlow.sourceRef | attribute | id of source flow element |
| 3 | sequenceFlow.targetRef | attribute | id of target flow element |
| 4 | incoming | element | id of prior sequenceFlow |
| 5 | outgoing | element | id of post sequenceFlow |
Map Inputs and Outputs of Workflow/Activity to Inputs and Outputs of an Activity
BPMN Field | XML attribute/element | Notes | |
|---|---|---|---|
| 1 | dataInputAssociation.sourceRef | element | id of source dataInput |
| 2 | dataInputAssociation.targetRef | element | id of target dataInput |
| 3 | dataOutputAssociation.sourceRef | element | id of source dataOutput |
| 4 | dataOutputAssociation.sourceRef | element | id of target dataOutput |
