Functioning of the attributes

Hi everyone,

I work with BeSimpleI18nRoutingBundle, but acualy I don't understand how it works with attributes.
I have my table with properties :

• route
• locale
• attribute
• lacalized_value
• original_value

What can I do or write in these attributes. I searched on the web about a tutorial, example but I found anything. Is there someone who can help me or explain how it works.

I work with Symfony 3.4.
Sorry but I'm lost... Have a nice day.

Is there someone ?
