                                          are depicting this data item. 

   description                            I       ndt_comment

                                          A description of the transient association. 

   duration                               IN      ndt_time

                                          Defines the duration of the association expressed
                                          in any valid units of time. 

   end_time                               IN      ndt_date_tod

                                          End time of the association. 

   start_time                             IN      ndt_date_tod

                                          Start time of the association. 

   caused_by                              I       activity

                                          Specifies the activity which establishes this
                                          association. 

   terminated_by                          I       activity

                                          Specifies the activity which established the
                                          termination of a transient association between
                                          two objects. 


positioning_part                          U       position_sensor_facility

                                          Indicates the positioning facility that is described
                                          as being a part of a whole facility. For a satellite
                                          receiver that is part of a seismic platform, this
                                          points to the satellite receiver. 

seismic_part                              U       seismic_facility

                                          Indicates the facility that is described as being
                                          a part of a whole facility. For a streamer section
                                          that is part of a streamer, this would point to
                                          the streamer section. 

whole                                     MU      seismic_facility

                                          Indicates the facility that acts as the whole
                                          for the part. For a streamer section that is part
                                          of a streamer, this would point to the streamer.
