==== Mid-long-term solution ====
===== Example =====
<blockquote>de_de:lidl
 
de_au:lidl
 
fr_fr:lidl
 
fr_be:lidl
 
hr_hr:lidl
 
xx_xx:lidl
 
wikipedia:en:<nowiki>https://en.wikipedia.org/wiki/Lidl</nowiki>
 
wikidata:Q151954
 
 
<de_de:lidl
 
de_de:snack day
 
xx_xx:lidl</blockquote>
 
 
In this example, we put de_de as first language because Lidl is a German company. Nevertheless, it should work the same starting with different language, at the condition that children refers to the parent accordingly.
 
==== Mid-long-term solution (to be defined/work in progress) ====
Same as before, adding:

***<u>'''Solution'''</u>: '''make the taxonomy country specific instead of language specific?'''
***<u>'''Solution'''</u>: es_es:frigo and es_cl:bresler / es_bo:bresler will be on the same block
*** For example, The Coca-Cola Company sells <code>Fanta</code> in Thailand under <code>Fanta</code> and <code>แฟนต้า</code> names.

***<u>'''Solution 1 (preferred)'''</u>: Synonyms  th: แฟนต้า, fanta  (+) they are at the same level of hierarchy  (-) only first synonym will be visible for users, have to opt for the most appropriate one (local language maybe?), or use both (eg: th: แฟนต้า / fanta, แฟนต้า, fanta)
***'''<u>Solution:</u>''' th_th:แฟนต้า/fanta, แฟนต้า, fanta in the same block as en_us:fanta
***<u>'''Solution 2:'''</u> different children for the same parent. Let's say we have parent "Coca Cola company", then we would have something like  xx: coca-cola company  <br /><xx: coca-cola company  xx: fanta th: fanta  <br /><xx: coca-cola company  xx: แฟนต้า  th: แฟนต้า  (+) Both should be visible for users  (-) we have two different entries for the "same" brand  (also by changing the website URL th.openfoodfacts -> world.openfoodfacts, we could see different names... Maybe  )
** Also synonyms. Product brand has changed over time.

** For [https://world.openfoodfacts.org/brand/walkers example], <code>Walkers</code> represents 3 different brands ([https://world.openfoodfacts.org/product/5000328123509/choux-de-bruxelle-walkers 1], [https://world.openfoodfacts.org/product/0039047003569/luxury-rich-fruit-cake-walkers 2] and [https://world.openfoodfacts.org/product/5011555031222/chocolate-gingers-walkers 3])

**<u>'''Solution'''</u>: having country specific brands would help as well as differencing Cervezas San Miguel and San Miguel. In long term we could have some set of rules like if it is San Miguel and category is Beers, then rename Cerezas San Miguel. Same for food vs cosmetic.

** <u>'''Decision:'''</u>
** <u>'''Decision:'''</u>
* EAN manufacturer codes - is there an open database which we could use?
* EAN manufacturer codes - is there an open database which we could use?
* country code vs language code.
** '''<u>comment @benbenben:</u>''' To tackle country specific brands (<nowiki>https://github.com/openfoodfacts/openfoodfacts-server/issues/2954</nowiki>), I would suggest to replace <language:> by <country:>. Because some names can differ per country instead of per languages (we can take the example of Miko/wall's ice creams (<nowiki>https://en.wikipedia.org/wiki/Wall%27s_(ice_cream))</nowiki> that are called Frigo in Spain but Bresler in Chile and Bolivia).  (+) that would make easier to detect if a product is in a wrong country based on the brand taxonomy  (-) not totally sure that we can do that technically, can we?  (-) it adds complexity because all other taxonomies have language code and only the brand taxonomy would have the country code  (+-) there may be some brands that divide a country in two (like Aldi), but not sure that it is an problem.
