=== Generic approach === | |||
The real-world quantities for products as used by the users us a far from ideal. However it is possible to find some common approach. (At least we try here) | |||
* to indicate times, either a "*" or a "x" has been used; | |||
* the generic formula is: multiplier * quantity * size_unit units | |||
** multiplier indicates how often a quantity unit is used, i.e. 6 (25 cl bottles). This is a number. | |||
** quantity the size of the units in size_units, i.e. 25 (size) cl (size_unit) bottles (units). This is a number. | |||
** size_units is the unit for the size parameter, i.e. kg, ml or cl. This is an enumerated? | |||
** unit is the element the numbers and sizes refer to, i.e. pot, bottle, sack, etc. | |||
