RDF Schema and Internationalization

I don't know if this is the right place or not.  I have been putting my 
first RDF schema together.  Can someone advise how I should deal with 
multiple language support or point me in the right direction.  I 
realize that you can attach a language attribute such as <rdfs:label 
xml:lang="en"> which I have done so that this is clear in my schema.

  I am not clear about how to deal with internationalize data however.  
Let's use a product as an example.  If it has properties (predicates) 
such as a hasSKU, hasTitle, hasDescription, the title and description 
properties could be in different languages. How does one deal with 
internationalization in the schema.  Do I have to create properties 
like hasTitleEn, hasTitleFr, hasTitleEs  etc. so my schema will handle 
multiple languagesor is there another way. It seems this approach would 
not be a very dynamic and involve much duplication in my schema which 
is already large. I would appreciate pointers on what I should do.  
Many thanks.
