Some experiences have been gathered in building the OFF taxonomy. These can be divided into guiding principles and steps.
   −
* Gathering - the first step is parsing the ingredient lists and ingredient entries - @stephane does this

==== Steps ====

To build the taxonomy from raw data, the follow steps need to be taken
 +
* '''Gathering''' - the first step is gathering the ingredients from the ingredient lists. This results in a list of ''raw ingredients''. This process needs to be described @stephane does this;
 +
* '''Assigning''' - the raw ingredients can be mapped unto the existing taxonomy, in order to find ingredients that are new and not yet part of the taxonomy (the ''new raw ingredients'');
 +
* '''Merging''' - each new raw ingredient must be looked at and if possible merged with an ingredient in the existing taxonomy;
 +
* '''Keying''' - if a new raw ingredient can be mapped to the taxonomy, it will probably be a new synonym of an existing entry. Ideally one should check which of the synonyms occurs the most and set that one as main ingredient name;
