the description of the data (the metadata) has to be homogeneized
preferably by some specialists, experts and users of the field.
That's what the vosphère eats and grows with.
Moreover it seem that depending of the chooseen descriptive parameters
you need to adjust their precision (in your description and/or in your 
data queries)
to be able to  handle simply nearby temperature (12000and 12300 °K) or 
gravity.
Why not using the old fashion spectral type :-[ ;-) :-D
