Data schema for localized (translatable) data

What is the optimal database schema for storing multi-language data? There are many examples around the internet, to list just a few:

• Multilanguage Database Design in MySQL
• Schema for a multilanguage database
• What's the best database structure to keep multilingual data?

They are all more or less based on the same idea, and are clear enough: There should be one table storing all language-neutral data of a model, and another table storing in each row a translation with the corresponding language code.

What I am missing here is how do I translate the actual meta-data for a model? For example, if I have a Product model defined with name, description and manufacturer columns, all three previous examples show how to store the translated content. The result would be:

(English) Product Name: Chair Description: A sitting product Manufacturer: Ikea (Spanish) Product Name: Silla Description: Un producto para sentarse Manufacturer: Ikea 

But how would I store translations for the actual model's taxonomy, such as Product, Name, Description, Manufacturer? In the examples above those are either a table name or column names. How do I structure my database to keep translations for those too?

I'm not sure if this is of any importance, but my app is built in PHP (using Laravel framework). And I do know that I could use PHP's gettext(), or store such meta-data in a method and return it as needed, but I would like to avoid that, as I believe storing it in a database provides much better flexibility.
