         This section specifies the template MoDAvDEXmessage_scheduled_maintenance.
         
      
      
         NOTE 
         The template has been defined in the context of 
         MoDAvDEX.

            This template describes how to represent a message reporting a scheduled maintenance activity. 
         
             
       
      
      
               
         
            Scheduled maintenance messages represent a record of a scheduled maintenance activity
            undertaken. The messages are triggered when a work order for scheduled maintenance is
            raised and when it is completed. Note that it is the same work order being referenced in
                    each message with progressively more information about the work done exchanged. 
                  
         
             
       
      
      
      
      
         The EXPRESS-G diagram in
         Figure

         shows the templates and EXPRESS entities that are required
         to represent the template 
         "MoDAvDEXmessage_scheduled_maintenance".
         The text highlighted in blue shows the template parameters.
         
      
 
                
                   
         
                        Figure 2

                        The templates shown in yellow in Figure 2 are
                        standard OASIS template. Those shown in light green are business templates developed
                        specifically for the MoDAvDEX context.

                             represent the reportable item and, if appropriate, its end item, parent or higher
                             assembly and position within the end item. The template also allows the properties,
                             such as life properties, of
                             the reportable item, the end and parent item, to be recorded.

                             the reportable item, the end and parent item, to be recorded.
                             This is used where the reportable item is versioned after work has been done.
                             If the Engineering and asset management system does not version assets, then
                             only use template #5.

                             the reportable item version after the work has been done. If he Engineering and asset management system does
               not version assets, then
                             templates: #7,#8 are not used.

         No common characterizations of the template 
         MoDAvDEXmessage_scheduled_maintenance
         have been identified. However, the ISO 10303-239 EXPRESS model
         may enable other assignments to the entities instantiated by the template.
