I think the best way to start my talk is to recall what kind of spectroscopic, information is available at present. Spectroscopic information can be of various kinds; starting from the simplest it may be:

a- a spectral type (unidimensional)

b- a spectral type plus a luminosity class (bi-dimensional type)

c- a description-more or less detailed

d- a quantitative analysis, which can be more or less sophisticated
