If it's not a part of the name, it shouldn't contain the number of portions or a quantity: bad examples are "1 Onglet", "10 Burgers", "1L Sirop cerise"; "100% Cacao", "1848 Lait noisette" (name of a product); it shouldn't contain registered trademark symbols ®, HTML code such as <code>&amp;quot;</code>; it shouldn't be in capital letters except if they are used on the product; it shouldn't contain brands except if it's included in the name ("Kinder Bueno" is good while "Kronembourg 1664", "Stella" or "Vodka Smirnoff" are not); it shouldn't contain price.

'''Question''': what do I enter when the label says something like "contains trace amounts of ..."?
 +

== Photos and data check ==
 +
At the end of the page, there is a specific section called "Photos and data check", documented as follow:
 +
 
 +
"Product pages can be marked as checked by experienced contributors who verify that the most recent photos are selected and cropped, and that all the product data that can be inferred from the product photos has been filled and is correct."
 +
 
 +
When <code>[x] Photos and data checked</code> is checked, Product Opener save the following data into the database:
 +
 
 +
* the value <code>on</code> in the field <code>checked</code>
 +
* the last checked date (Unix timestamp format) into <code>last_checked_t</code>. Eg. <code>last_checked_t: 1704906819</code>.
 +
* the last user who checked the product into <code>last_checker</code>. Eg. <code>last_checker: benbenben</code>.
 +
* the users who have checked the products are stored in the field <code>checkers_tags</code>. Eg. <code>checkers_tags: ["benbenben","stephane"]</code>.
 +
 
 +
When <code>[x] I checked the photos and data again</code> is checked, Product Opener update the following data:
 +
 
 +
* the last checked date (Unix timestamp format) into <code>last_checked_t</code>.
 +
* the last user who checked the product into <code>last_checker</code>.
 +
* the users who have checked the products are stored in the field <code>checkers_tags</code>.
 +
 
 +
 
 +
When a product is checked, this information is given on the product page, in the '''Data sources''' section, eg. "Last check of product page on January 10, 2024, 6:13:39 PM CET by charlesnepote".
 +
 
 +
These data can also be retrived via the API.
 +
 
 +
It's possible to explore the checked products with the dropdown menu "Explore products by...", selecting "Last checked dates", leading to the page: https://world.openfoodfacts.org/last-check-dates
 +
 
 +
It's possible to combine facets, for example, to get last checked dates of the TOP-1000 products in a country, eg. https://world.openfoodfacts.net/popularity/top-1000-fr-scans-2022/last-check-dates
