[Koha-devel] Authorities localization?

[Joel Cornuz]

Hi there,

My name is Joel Cornuz, I am the IT manager for a small school in
Montreal using (with success!!!) Koha for its library (15k volumes).
Many thanks for this great tool that is giving us access to a world
class library system!!!

I am not sure if this is the right place to ask (feel free to redirect
me if required) but here is the question:
Our books are a mix of French and English volumes and we would like to
translate our authorities (the topical terms). The idea is that we want
our students to have access to topical terms in French or in English,
and access to our complete collection (French and English volumes)
related to this particular topic.

I know that it is possible to duplicate an authority - so one idea was
to duplicate (and translate) authorities... but then I didn't find a
simple way to automatically link items from the source to the duplicated
authority (am I missing something there?)

Or is there a way to localize existing authorities? 

Or is there another (different, better) way?

Thanks for your help and thanks for Koha!

Take care,

Joel
