== Current status == | |||
=== Data entry === | |||
* There is a field to indicate the "main" language of a product | |||
** Values entered in the product edit form are considered to be in the "main" language of the product | |||
** Values entered in fields for which we have a taxonomy (categories, countries, labels, traces) are mapped according to the "main" language of the product | |||
*** e.g. entering "jus de fruits" in the categories field when the main language is set to French will result in en:fruit-juices to be assigned. | |||
* Values for nutrition facts are global and assigned to a canonical field | |||
** Except when the nutrient's name is unknown (i.e. not in our current nutrient taxonomy) | |||
* Images are selected/cropped for the "main" language of the product (product front, ingredients and nutrition facts) | |||
=== Data display === | |||
* Fields for which we have a taxonomy (categories, countries, labels, traces) are displayed in the target language. (target language is set by the subdomain, e.g. using http://world.openfoodfacts.org , we will see categories in English even for French products, using http://es.openfoodfacts.org will result in Spanish) | |||
** Only if the category exists in the taxonomy | |||
** Only if the target language exists for this category in the taxonomy | |||
*** If the target language doesn't exist, English is used to display the field value | |||
* Nutrition facts are displayed in the target language | |||
* Fields without a taxonomy are displayed in the language they were entered in | |||
** common name, quantity, packaging, brands, origin of ingredients, manufacturing or processing places, city/state/country, stores, link to the product page, best before date | |||
** ingredients | |||
* Images for product front, ingredients and nutrition facts are for the main language of the product (and not the target language) | |||
== Solution == | |||
=== Data entry === | |||
* Taxonomize as many fields as possible | |||
** Taxonomized field need to be completed in only one language | |||
** Packaging, origins of ingredients, purchase places | |||
*** Note: packaging and purchase places do not correspond to text on the label | |||
* Enable users to enter data for more than one language: | |||
** Select different images or different part of the images for product front, ingredients and nutrition facts | |||
** Enter data (text) for more than one language | |||
=== Data display === | |||
* Taxonomized fields will be displayed in the target language | |||
* Display other fields and pictures in the target language if the product has data in that language | |||
* Indicate in which languages the product data is available, and provide a way to see it | |||
=== Technical design === | |||
==== Taxonomize all or most multilingual tag fields ==== | |||
* Packaging, origins of ingredients and purchase places are tag fields (they contain comma separated values) that are not yet taxonomized | |||
* The existing taxonomy system will take care of the mapping between different languages | |||
* The taxonomies need to be created or completed | |||
* To be determined: what to do with brands? | |||
** Typically not translated | |||
*** But exceptions exist | |||
** Could benefit from being taxonomized in order to have a hierarchy | |||
==== Selection/crop of images in more than one language | |||
* For product, ingredients and nutrition facts | |||
==== Entry of fields in more than one language | |||
* Keep all exisiting fields as-is | |||
** e.g. ingredients, generic_name etc. | |||
** "ingredients_text":"Chocolate, milk" | |||
** For compatibility and to enable incremental implementation and deployment | |||
* Create new fields suffixed by _lang, with a hash | |||
** "ingredients_text_lang":{"en":"Chocolate, milk", "fr":"Chocolat, lait"} | |||
* Create new languages field | |||
** Hash that contains languages for which we have values for at least one field | |||
** "languages":{"en":"1", "fr":"1"} | |||
