Legal values from AOS20:

• "CREATE"
  First event. The flight leg has been created. Creation is alway from only one source, given in CreatedSource.
• "UPDATE"
  The flight leg has been updated. Most common event. One update can include data from multiple sources.
• "DELETE"
  The flight leg has been removed/deleted. It will never be reinstated and should just be remover/deleted in all systems.
• "MERGE"
  This flight leg has been merged into another flight leg, identified by MergedIntoUniqueFlightLegId.
• "REQUEST"
  The data set has been produced as a result of a call to FlightLegDataRequestService.

NB! CreatedSource will be the first element in DataSources.

The content of CreatedSource is the SecurityContext from the transaction that created the flight leg, or the user name if the flight leg was created manyally. See also: AodbTransData.

The organization that is the source of CreatedSource.

CreatedTimestamp

NB! As data comes from a new source, and is matched to one flight leg, the SecurityContext representing the source is just added to the DataSources list regardless of the new data actually updating the flight leg or not. 

See also: AodbTransData.

NB! In some cases DataSources can be longer than allowed by the type. In this case sources should be removed from the DataSources string until it is within the allowed length. Remove the sources starting with the oldest. The first source to be removed would then be the CreatedSource.

NB! ClassificationLevel = "PUBLIC" does not mean that all information, like passenger numbers, are public information, only that the flight leg itself is. 

Default value is "NON-PUBLIC".

See Specification: ClassificationLevel for a detailed description of which flight legs to set to PUBLIC.
