A large chunk of binary data takes up less space than its encoded representation, so MTOM can reduce transmission time (although it incurs some processing overhead).

The theory of SM believes that the representation of SM concerns at least five dimensions, such as (1) space, (2) time, (3) entity, (4) causality and (5) intention.

By choosing a region at random from the map and making any combination of time and space, user "s demands of data and data" s representation are met.
