WorkflowDef

A WorkflowDef defines an automated workflow for a study.

Element Name	WorkflowDef
Parent Elements	MetaDataVersion
Element XPath(s)	/ODM/Study/MetaDataVersion/WorkflowDef
Element Textual Value	None
Attributes	OID, Name
Child Elements	(Description?, WorkflowStart, (Transition?, Branching?)+, WorkflowEnd+)
Usage/Business Rules	Other Information: Workflows can be nested, by referencing a StudyEventGroupDef that references another WorkflowDef element. In this way a workflow can consist of several subworkflows. A workflow for the study as a whole will typically be described in a WorkflowDef referenced from the Protocol element. Workflows that are valid for a "study cell" (as described in the SDTMIG) will be described in a WorkflowDef referenced by a StudyEventGroupDef representing a study cell (i.e., ArmOID and EpochOID are populated). References to the SDTMIG correspond to the SDTMIG v3.3, last Production version at the release of the ODMv2 Specifications. Workflows that are valid for a study element (as described in the SDTMIG) will be described in a WorkflowDef referenced by a StudyEventGroupDef without ArmOID and EpochOID populated, and by a "parent" StudyEventGroupDef representing a study cell (i.e., ArmOID and EpochOID are populated.

Attribute	Schema Datatype or Enumeration	Usage	Definition	Business Rule(s)
OID	oid	Required	Unique identifier for the workflow.	The OID attribute value must be unique within the Study.
Name	name	Required	Human readable label for the workflow.	The Name attribute value must be unique within the Study.

Physio- or Underwater therapy Workflow Example

This example demonstrates a simple workflow where the patient is either undergoing physiotherapy or underwater therapy, or both. This example was automatically generated from a BPMN2-XML file using an XSLT stylesheet.
