[Gnumed-devel] Medication schema - how to represent concentration

[Jim Busser]

Presently, ref.consumable_substance offers only

        amount - numeric
        unit - text

Which will handle ibuprofen:

        600 mg

and tobacco:

        1 pack

but how shall I store entities like

        13.7 g / 100 g (for example medication in creams)

        50 mg / 5 ml (for example cough syrups)

??

Shall I make

        amount = 13.7
        unit = g / 100 g

        amount = 50
        unit = mg / 5 ml
        
??
