Billa maps directly to the canonical categories. Spar uses a mapping file stores/spar-categories.json. Each store has a generateCategoryMapping() function which is called once in analysis.js:updateData() and analysis.js:replay(). The function is responsible for * Fetching the latest categories * Merging them with already mapped categories * Report new categories that haven't been mapped yet * Report categories that have been mapped but are no longer part of the latest set of categories * Save the merged mappings to disk This schema might not work for all stores, in which case updateData() and replay() will use a knn approach to figure out the category for an item.
