mesh normals

Hi,
In my application I need to generate a file which describes a surface mesh and, for each triangle, provides the following data:
 The coordinates and the normal vectors associated with the following 7 Points:
the triangle vertices + the centers of the triangle sides + the center of the triangle
I need the exact normals related to the underlying surface (and not an approximation which is derived from the triangulated surface)
I would like to know if it is possible to generate this data using the Salome Platform
or if there is any plan to include this capability in a future release.
Many thanks for your kindly attention
