S124 Guidelines for STM

1. 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:

1. Navigational warning Preamble (NW_Preamble)It’s mandatory part of warning which gives general information about event.2. 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.

3. 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.

4. 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 cases the end user should receive such messages too in order to see when such

messages were cancelled by shore center.

2. 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 rules can be applied to fill in the fields Message Series Identifier for local warnings:

Country=SEProduction Agency=SMANameOfSeries=Oregrund VTStypeOfWarning=localWarningNumber=intYear=2017

Attribute Source Date is the date of message’s publication.

Attribute General Category defines category of event.

The user should have possibility to use filter tool by General Category

Attributes General Area (as a main area) and Locality (as a sub-area) are applied to describe geographical coverage.

Below list of proposed general areas for drop-down list: Skagerrak Kattegat Lake Vänern and Trollhätte Canal The Sound The Belts Western Baltic Southern Baltic South-eastern Baltic Central Baltic Lake Mälaren and Södertälje Canal Northern Baltic Gulf of Riga Gulf of Finland Sea of Åland and Archipelago Sea Sea of Bothnia The Quark Bay of Bothnia Other lakes and canals

Attribute Title contain main text information about event. It includes general text for nav warning.

Attribute FixedDateRange – Validity Period when the event takes place. When Validity To (timeEnd/ dayOfEnd) is specified then the Nav warning will be cancelled if otherwise is not specified.

The next use case is possible. For instance, the event as military exercise takes place. Attribute FixedDateRange is filled in in the NW_Preamble (from 21-00 01.05.2017 to 21-00 03.05.2017). But this warning is continuing in force till 00-00 04.05.2017. In this case the References Part shall be filled in in which the conforming Date attribute (cancellationTime) is filled in (see the Use case 4 in the Annex below)

If any time/Date attributes are absent in the Nav Warning (or dateofEnd of event is unknown when warning publishes then this warning will be cancelled in the future after publication such cancellation in the separated or in other Nav warning (see the section 5 – Comments on References part)

Attribute AffectedCharts – references on an ENC or Paper chart’s numbers to which they may referred to or related to (optionally)

Links: NW Preamble can be linked with other parts of messages as Navigational warning Part, References Part, Information Notice Part.

Client software:The next elements (fields) can be used from NW_Preamble by client applications:ID – based on gml:id from Preamble without letters “ PR. “. For instance, if we have the next gml…<imember>

<S124:S124_NWPreamble gml:id="PR.SE.059.17"><id>urn:mrn:s124:NW.SE.059.17.P</id>

…Then ID will be as SE.059.17NameOfSeries + WarningNumberSourceDateGeneral area\ LocalityGeneral CategoryValid from – Valid toTitle AffectedCharts

3. Comments on Navigational Warning Part

The Navigational Warning Part contains information about geometry/areas and linked attributes.

Each area may have own semantic information as text description (attribute “Subject”) and Validity Period (attribute “FixedDateRange”).

Several Validity Periods are possible for one area, for instance: when some works are carried out during several days at the defined time period

Also the message (Nav Warning) may contain two areas (or more) with different Validity Periods.In this case each area may have own text description and own Validity Period

Links: Nav Warning Part can be linked to the NW Preamble only.

Client software:The next elements (fields) can be used from Navigational Warning Part by client applications:extReferenceId – reference on an event, objects which are out of scope of current format (other

services)GeometrySubject – descriptive part for the geometryFixedDateRange – time period for geometry objects. Several periods can be assigned by Operator.

4. Comments on Information Notice Part

Information Notice Part is the descriptive part of event that has no geometry coordinates.

This part can be applied to specify additional information that relates to the General area in the NW Preamble. For instance, information about ice conditions in the gulf of Finland or some web-site suspension due to technical issues. Also these can be specified other notifications as text about cancellation of previous message.

The Information Notice Part may contain the next attributes: textual description as attribute “Subject”, and Validity Period (attribute “FixedDateRange”). This Part can be used as an addition to the Information specified in the NW Preamble.

Links: Information Notice Part can be linked to the NW Preamble only.

Client software:The next elements (fields) can be used from Information Notice Part by client applications:Subject – descriptive part as a text

FixedDateRange – time period for described event in the attribute “Subject”. Several periods can be assigned by Operator.

5. Comments on References Part

The main purpose of References Part is to cancel of previous messages without replacing of existing warnings in the onboard storage

The onboard database of navigational warnings for onboard applications shall update by receiving of new navigational warnings that may include messages with cancellation of previous messages.

This part is needed to cancel previous published messages if the time/date of End of event were not filled in in the primary navigational warning. Then the current nav warning will have contained a reference on the previous message. In this case, the Reference part will be included the reference on the Message Identifier and the attribute “ReferenceType” as Cancellation.

For instance: The nav warning like below is possible

<imember><S124:S124_NWPreamble gml:id="PR.FI.034.17"><id>urn:mrn:s124:NW.FI.034.17.P</id>

</messageReference><header xlink:href="NW.FI.034.17"/>

</S124:S124_References></imember>

In this case the end-user shall see the next fields only:ID: FI.034.17

Publish Date: 31.01.2017Name: Finnish nav warn №34Text: Cancel 023/17

Also the References part can be used to specify attribute in force for nav warning with date of cancellation. If the current Nav Warning shall be cancelled at the defined time in the future then it shall include the reference on it’s own Message Identifier and attribute “cancellationDate” – when the message shall be cancelled. These use case are specified in the Annex “Use cases” below.

Links: References Part can be linked to the NW Preamble only

The new SAR area has extended bounds. The related information can be specified in the area message accordingly.Also, in the current message, the Shore center (Operator) can cancel the previous message. In this case the end-user will be seen the new message (new geometry and related attributes) and plus notification about cancellation of previous message. In our case this is “Cancel SE.local.51.17”. Simultaneously the message status should be changed – from “in Force” on “Cancelled”

<imember><S124:S124_References gml:id="NW.SE.local.52.17.2">

Possible scenarios for message’s cancellation

Introduction:

In general, NW Service should provide all actual messages by the received requests.If these messages include references for cancelation of previous messages then the possibility to receive canceled messages should be provided too.But there are different situations when we need to see full life cycle of Nav warning including deleted status. Also it’s possible that NW Service won’t operate some time. Then, in this case, we need to handle messages using the filled in attributes.

Use case 1:Event takes a place in defined bounds.Also the event has validity periodThe S124-message contains two parts only:

1. S124_NWPreamble – general information2. S124_NavigationalPart

In this case cancellation of the message will have happened by the attribute FixedDateRange (timeofDayEnd/dateEnd) in the S124_NWPreamble

Use case 2:Event takes place in defined bounds. This event includes two areas.Also the event has validity period but validity period is specified in the S124_NavigationalPartThe S124-message contains three parts only:1. S124_NWPreamble – general information without validity period2. One area is one S124_NavigationalPart. So we have two S124_NavigationalParts. They contain own area and each area has own validity periodIn this case, cancellation of the message will have happened by the attribute FixedDateRange (timeofDayEnd/dateEnd) when the latest time/date will have come from two periods in the S124_NavigationalParts<imember>

Use case 3:Event takes place in defined bounds.But this event hasn’t validity period. The event has start date/ time only in the S124_NWPreambleThe S124-message contains only two parts:1. S124_NWPreamble – general information without validity period2. S124_NavigationalPart - it contains one areaIn this case, cancellation of the message will have happened after receiving of another future message in which will be fill in the References Part: the reference on the required message, and time/ date of cancellation can be specified too.

Another event takes place in which previous message will be cancelledThis S124-message will contain the next parts:

1. S124_NWPreamble – general information about new event2. S124_NavigationalPart - description of geometry for it contains

one area3. S124_ReferencesPart – message reference on the previous

message that is required to cancel
