The real-world quantities for products as used by the | The real-world quantities for products as used by the user (and printed on the packages) is not ideal. It is often impossible to parse the quantities and understand what is indicated. | ||
However it is possible to find some common approach. This is a first attempt. | |||
Some remarks: | |||
* product central - any quantity that is indicated is about the product and not the packaging; | |||
* equivalents - one or more equivalents might be available, i.e. in grams or liters, 24 cookies / 6 cookies in 4 packages; | |||
* containers - the generic toplevel package is a container; | |||
* subcontainers - a container might comprise multiple subcontainers (or even subsubcontainers) [hierarchy?] | |||
* (sub-)container synonyms - a user might container other words to describe a container, such as bottle, can, bag, etc. | |||
* defaults - in indicating the quantity some parts are assumed to be understood. If it states 33cl it is assumed to be about the container (the bottle) and the product (beer); | |||
