A Transition defines a link between two 2 structural elements in a workflow.

...

The TargetOID references the definition of the target  target structural element of the transition. This can be a StudyEventGroupDef, StudyEventDef, ItemGroupDef, ItemDef, or Branching element.
The latter will be used when there is a branching definition necessary as a result of the transition.

The StartConditionOID references a ConditionDef specifying a condition that must be met for the transition to start. For example  example, if the source structural element is a StudyEventGroupDef describing the activities for study screening , and the target structural element is a StudyEventGroupDef describing study enrollment,   the ConditionDef referenced by the StartConditionOID specify specifies the criteria that must be met for a subject to transiton transition from Screening screening to Enrollmentenrollment.

The EndConditionOID references a ConditionDef defining the condition under which the transition can be completed. As long as the condition is not met, the transition to the next actitivity or event must be considered to be temporary blocked. When the target structural element can be considered to be a "visit," , the condition can be regarded as a visit entry criterion.

When the execution of the transition is depending on dependent upon a timing constraint that is either directly defined or calculated, a TransitionTimingConstraint must be definedand referencing , referencing the current Transition.
