I'm looking for best practice concerning the keys you use for your resource bundles properties keys. And advantages/drawbacks you know about what you are using. First i used some context prefixed English strings like: Registration_AskLogin = Please enter a login Connection_AskLogin = Your login The main advantage not seen on this example, is that it gives a bit of context for the translator, it helps sometimes. I could use: Please_enter_a_login = Please enter a login Your_login = Your login But in some language and certain scenario, "Your login" could be said in a different manner depending on the context. I could also use: Please\ enter\ a\ login = Please enter a login Your\ login = Your login But that would suck ;) JSF EL wouldn't like it. Thanks if you can help.
