Some products have a different value for lang and lc

[stephanegigandet]

What

• All products should have lang = lc, and the value corresponds to the main language of the product field.
• Example: https://fr.openfoodfacts.org/api/v0/product/0886002700151.json?fields=lang?rev=23
• Example fixed: https://fr.openfoodfacts.org/api/v0/product/0886002700151.json?fields=lang

Here's another one: https://us.openfoodfacts.org/api/v0/product/4970077115289.json?rev=32 Saving it, but not deliberately changing anything language related, made them the same again: https://us.openfoodfacts.org/api/v0/product/4970077115289.json?rev=33

To copy some ideas from Slack. The query and json should be able to encode the following situation.

I would like to show my greek friend on my english device, the dutch products sold in Belgium. Any relevant information will be translated to greek.

[stephanegigandet]

I think the issue of the products with lc != lang comes from the import of the USDA or producers data. It can change the lc field value without changing the lang value.

In a query this would imply:

• domain gives the product from Belgium
• lang=nl, gives the dutch products
• lc=el, any translatable fields (allergens, ingredients, attributes) will be in greek.

[svensven]

can't you already do that sort of thing with https://be-el.openfoodfacts.org/cgi/search.pl?action=process&tagtype_0=languages&tag_contains_0=contains&tag_0=en:dutch ?

Ah. it translates on the site, but not in the json.

I clarified @stephanegigandet 's original example (that got fixed) by adding the field parameter.
