Relation pm#spatial_relation_to_entity_with_spatial_feature (*,object)
  exclusion:  relation_to_situation  relation_to_time  relation_to_collection  relation_to_attribute_or_quality_or_measure
  supertype:  relation_from/to_thing_of_common_kind  this type permits to categorize relations according to their signatures and hence offers (i) a concise way to set essential exclusion relations, and (ii) a systematic and easy-to-follow categorization
  subtype:  relation_to_spatial_object (*,spatial_object)  in WebKB, prefer using relations "from" a spatial object
     subtype:  relation_to_another_spatial_object (spatial_object,spatial_object)
        subtype:  location (spatial_object,spatial_object)
           subtype:  address__addres (spatial_object -> spatial_object)
              subtype:  main_address (spatial_object -> spatial_object)
              subtype:  secondary_address__secondaryaddres (spatial_object -> spatial_object)
           subtype:  above (spatial_object -> spatial_object)
              subtype:  on (spatial_object -> spatial_object)
           subtype:  below (spatial_object,spatial_object)
           subtype:  near (spatial_object -> spatial_object)
              subtype:  touching (spatial_object -> spatial_object)
           subtype:  far_from__farfrom (spatial_object,spatial_object)
           subtype:  exterior__in (spatial_object -> spatial_object)
           subtype:  interior (spatial_object,spatial_object)
           subtype:  before_location__before (spatial_object,spatial_object)
        subtype:  spatial_part__spatialpart (spatial_object,spatial_object)
           subtype:  physical_part (physical_entity,physical_entity)
     subtype:  where_fn__wherefn (physical,time_point -> region)  maps an object and a time_point at which the object exists to the region where the object existed at that time_point
  subtype:  partly_located__partly_located_at (physical,object)  the instance of the 1st argument is at least partially located at the 2nd argument, e.g., Istanbul is partly located in Asia and partly located in Europe
     subtype:  contains (self_connected_object,object)  the relation of spatial containment for two separable objects; when the two objects are not separable (e.g., an automobile and one of its seats), the relation of part should be used; (sumo#contains ?OBJ1 ?OBJ2) means that the self_connected_object ?OBJ1 has a space (i.e. a hole) which is at least partially filled by ?OBJ2
     subtype:  located (physical,object)  the 1st argument is partly_located at the object, and there is no part or sub_process of the 1st argument that is not located at the object
        subtype:  exactly_located (physical,object)  the actual, minimal location of an object
