• Other Information:
  • When the comment is provided in an external file, the def:leafID attribute must be included and the Description element can include a short descriptive reference to the external file.
  • Note a unique CommentOID and can be referenced from mutltiple elements.

• • 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.
