This key briefly describes the event, change, or circumstances that caused the feature to come into existence. This description often helps to clarify the reason why the OHM feature exists from a certain start_date=*, even though the feature existed in the real world prior to that date. For example, OHM might have a separate feature due to a renaming or move.

Examples

• 

  start_event=Westbound trains arrive in Omaha and head to San Francisco on a grand opening journey

•

•
