the non-technical part

John and everybody:

       i noticed that in the title it marks the "non-technical" ,  just as we understand it may cause the potential obstruction for its likely "unprofessional" background.at last  the saddest result might be we construct an useless description. In this point,  i agree with the idea   of peter.

       in my opinion, at least, for the reason of supervision by some government's department or the information should be revealed defined in some laws, this type API that supports information aggregation should be defined and encouraged to realize for the  public service.
