modelling questions in a domain of language

Dear all;

How are you?
I have a quick question about modelling an ontology.
I am doing a modelling about language and language code such as ISO639-1 and
ISO639-2.
First, I created a class called "language". 
I have two question on that.
1) Do I create another class called "language code" and create object
property called "has Code"  between both classes? or Do I create  two data
type property called "hasISO639-1code" and "hasISO639-1code"?
Could you tell me your opinion?

2) I would like to put multilingual names in each language(i.e. English in
English, Inglésin Spanish, Anglais in French. and so on). Then, how do I
model this kind of multilingual information? I have two options: One is using
datatype property called "hasEnglishName" and the other is <rdfs:label
xml:lang ="en">English</rdfs:label>. Is there anyone who has the same
experience then could tell me which one is better? 

Thanks for your answers or comments in advance.

Best Regards,
Soonho Kim
