10、ontains one of the following modifiers in the verb area: ADD, CHANGE or DELETE.The timing of the publication and scope of the published information is not defined in a message. It is determined by an out-of-band agreement between the publisher and subscriber.EXAMPLE This verb is commonly used when m
11、ass changes are necessary, such as when a device publishes an update for multiple systems or when a publish-subscribe mechanism is used as a companys integration architecture.A SYNC ADD verb is sent by the owner of the information and indicates that the owner of the information has added new informa
12、tion. The SYNC ADD message includes the object instances added and the values of all attributes of these objects.Information provider Information userSYNC ADD with CONFIRMCONFIRMLocal processingFigure A.6 SYNC ADD transaction with confirmationA SYNC CHANGE verb is sent by the owner of the informatio

The information can still be archived or retained in accordance with business policies, but is not available for further publishing. The information user has the responsibility to determine the
16、correct action, such as retaining or archiving their information.A.1.1.3.1.3 Responding verb descriptionsA.1.1.3.1.3.1 SHOWThe SHOW verb is used when responding to a GET message.Figure A.8 illustrates a transaction with a GET message followed by a SHOW message and a CONFIRM message (because of the “

The message data area contains an identification of the type of modification.EXAMPLE Figure A.10 shows a CM&D monitoring schedule (route) sequence sent from a master CM&D configuration system to a CM&D execution system. The initial PROCESS message with a monitoring schedule is rec
23、eived with a specified polling periodicity and an ACKNOWLEDGE message with a MODIFIED flag is returned with a longer polling periodicity since the execution system calculated that the requested one was not possible for execution. Upon receipt of this modified schedule, the CM&D monitoring scheduling
24、 system decides to shorten the schedule by removing a sensor, but keeping the periodicity as first requested and resends this to the CM&D execution system. The CM&D execution system accepts the schedule and returns an ACKNOWLEDGE message with an ACCEPTED flag.Master Config SystemCM&D ExecutionSystem

26、 for confirmation of receipt and processing of any message other than the CONFIRM, RESPOND or ACKNOWLEDGE messages. See Figure A.11 for an example of confirmation with detected errors.Confirmation is an option controlled by the sending business application. It is a request to the receiving applicati
27、on to send back a confirmation message to the sender of the initiating message.The CONFIRM message indicates an identification of the initiating message being confirmed.The CONFIRM message indicates the successful processing of the initiating message or returns error conditions if the initiating mes
28、sage could not be processed. The error condition should include a description of the error. ISO 2012 All rights reserved 17BS ISO 13374-3:2012ISO 13374-3:2012(E)If an error occurs in the processing of the initiating message by the receiving application and the sender has set the confirmation element
29、 to either OnError or Always, then the receiving application provides a CONFIRM message. If no confirmation option was specified, then the default value is Confirm Never.Error handling at the application layer is through the confirmation element in the application identification area.The application
30、 error handling is in addition to any communication layer error handling that may be provided by the infrastructure framework, web service or middleware.A confirmation request has the values defined in Table A.6.Table A.6 Confirmation request optionsName DescriptionNever No confirmation requested.On

34、E message. The RESPOND message is used when responding to a CHANGE message. The RESPOND message may return the original or modified data.A RESPOND verb area contains an element with one of the following additional definitions: ACCEPTED, REJECTED or MODIFIED.
