Entity spatial_object

• Spatial objects are topological elements, such as region, face, edge, and vertex, which can have geometrical representation. Subtypes of business object or technical object may be typed according to their spatial topology.

Subtypes:

simple_spatial_object, composite_spatial_object

   secondary_topological_relationship     IV      set[0 .. N] of (topological_relationship)

                                          Indicates a topological relationship in which
                                          the object is in the role of secondary agent.
                                          For an object intersection type of "inside" this
                                          is the contained role (e.g., if a well is inside
                                          a field then the well would be the secondary agent).
                                          For all other object intersection types the roles
                                          are symmetrical and both relationships must be
                                          searched for a particular object. For example,
                                          if a wellbore and a formation overlap then either
                                          could be chosen as the secondary agent with the
                                          other chosen as the primary agent. 

   primary_topological_relationship       IV      set[0 .. N] of (topological_relationship)

                                          Indicates a topological relationship in which
                                          the topologic object has the role of primary agent.
                                          For an object intersection type of "inside" this
                                          is the containing role (e.g., if a city is inside
                                          a county then the county would be the primary
                                          agent). For all other object intersection types
                                          the roles are symmetrical and both relationships
                                          must be searched for a particular object. For
                                          example, if a wellbore and a formation overlap
                                          then either could be chosen as the primary agent
                                          with the other chosen as the secondary agent.

   intersection_role                      IV      set[0 .. N] of (space_time_operation)

                                          Indicates a space/time operation for which the
                                          object is involved as an intersecting agent. For
                                          projection, this is the screen on which an object
                                          is being projected. For proximity, this is the
                                          magnet object. 

   primary_role                           IV      set[0 .. N] of (space_time_operation)

                                          Indicates a space/time operation for which the
                                          object is involved as a primary agent. For
                                          degeneration, this object is being degenerated.
                                          For projection, this object is being projected
                                          onto another object. For proximity, this is the
                                          container object. 

   source_space_time_operation            IV      bag[0 .. 1] of (space_time_operation)

                                          Indicates the space/time operation from which
                                          a topological object was the result. For addition,
                                          this is the union of two objects. For degeneration,
                                          this is the degenerate object. 


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

                                          Defines the set of composite spatial objects of
                                          which this spatial object is a component. 

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

                                          Indicates various earth models which include this
                                          spatial representation.
