                                          The name by which this set of data will be identified.
                                          The name will generally include some high level
                                          indication of the processing state of the data
                                          (e.g., "migrated final", "filtered brute", "semblance
                                          panels w/residual statics", "test 5"). 

seismic_processing_activity                       seismic_processing_activity

                                          This defines the activity which created this data
                                          set. 

derived_from                                      seismic_data_set

                                          This defines the data set from which this data
                                          set was derived. This excludes secondary data
                                          (e.g., velocities, statics) which influenced the
                                          algorithm that modified the data. 

ref_processing_indicator                          list[0 .. N] of (ref_processing_indicator)

                                          This defines the list of "high level" indicators
                                          of the processing steps which have occurred in
                                          the processing history of this set of data. For
                                          example, refraction statics, deconvolution, filter,
                                          moveout, stack, filter, migrate, etc. The non-unique
                                          ordered list allows the same type of processing
                                          to occur more than once (e.g., filter before and
                                          after stack). In general, this list should match
                                          the processing of the "parent" data except that
                                          new steps may be added. 

applied_data                                      set[0 .. N] of (seismic_data_set)

                                          Defines the sets of data which have been applied
                                          directly to this data set. 

ref_naming_system                         U       ref_naming_system

                                          Defines the naming system associated with the
                                          name of this set. This might refer to the naming
                                          system of a corporation or to a personal naming
                                          system. This will prevent name conflicts between
                                          companies, sites and/or persons. That is, a corporation
                                          or an individual may dictate that the name of
                                          this set is "brute stack" and we may instantiate
                                          another instance for the same line which was named
                                          "brute stack" by a different associate (i.e.,
                                          different naming system). 

seismic_line_segment                              seismic_line_segment

                                          The "line" segment represented by the data in
                                          this set. 

seismic_geometry_set                      MU      seismic_geometry_set

                                          The acquisition geometry that this data represents.
                                          For example, a 2D line, a 3D survey or a regional
                                          composite. 

seismic_header                                    seismic_header

                                          Defines the header which provides information
                                          about the grid. If a header is specified, then
                                          the grid used by the data must directly or indirectly
                                          use the same grid as is used by the header. 

binset                                            binset

                                          Defines the binset whose grid is directly or indirectly
                                          used for the grid of the data.

                                          Defines the geometry set which specified the grid
                                          being directly or indirectly used in the data.
                                          This may represent, for example, the field trace
                                          uid grid. 

seismic_display                           V       set[0 .. N] of (seismic_display)

                                          The set of displays which primarily represent
                                          this data set. 

derived_data                              V       set[0 .. N] of (seismic_data_set)

                                          This defines the set of data sets that are created
                                          as a direct result of modifying or analyzing this
                                          data set. This does not include children-of-children
                                          but does include secondary data such as residual
                                          statics or velocities which were derived from
                                          the parent. 

seismic_offline_data                      V       set[0 .. N] of (seismic_offline_data)

                                          Defines the offline data which is represented
                                          by this data set.

                                          Defines the geologic features which have been
                                          interpreted to appear on this data and classifies
                                          their appearance.

                                          may have a property of 

pty_geometry_1d_edge                      V       set[0 .. N] of (pty_geometry_1d_edge)

                                          may have a property of

                                          This defines the data sets that this data has
                                          been applied to. This should not also point to
                                          the children of the data set unless this data
                                          was also directly applied to the child.
