S124 Guidelines for STM General comments S124 format by itself is developed for transmission Navigational warnings from shore centers to the ships. The current format corresponds to the next aims: 1) to transmit urgent marine safety information on the vessels; 2) to provide full life cycle transmitted warning beginning from it’s creation to cancellation of this warning The message (navigational warning) may contain the next parts: Navigational warning Preamble (NW_Preamble) It’s mandatory part of warning which gives general information about event. Navigational warning part (NavigationalWarningPart) It’s not mandatory part that should be filled in if some event takes place at the defined coordinates. This part includes geometry information (point, line or polygon) and semantic attributes related to the specified geometry objects. Information Notice Part (InformationNoticePart) It’s not mandatory part that contains description of the event, but without exact references to geometry / polygons (it might be related to the whole NAVAREA area, or just to the any specified general area, for example: gulf of Finland. If geographic coordinates can not be determined then Navigational warning should include Information Notice Part. References part (ReferencesType) The References part is needed to cancel previous warnings or to specify that current warning may remain in force some time after event’s completion. At all the end user should receive such messages too in order to see when such messages were cancelled by shore center. Comments on NW Preamble Each Navigational Warning contains general information about event. Message Series Identifier (complex attribute) shall consist of country, productionAgency, NameOfSeries, typeOfWarning, WarningNumber, Year. These rules should be implemented for managing URN id (by the production system). For instance, the next can be applied to fill in the fields Message Series Identifier for local warnings: Country=SE Production Agency=SMA NameOfSeries=Oregrund VTS WarningNumber=int Year=2017 Attribute Source Date is the date of message’s publication.
