Question

Is it possible to restrict access for a given Sitecore editor role to a specific language version of an item in Sitecore?

I am considering a site which would be multi-lingual where there is the requirement to allow editors in the appropriate country edit content for that country, but not have write access to the content of other countries. Would the only way to achieve this be to create duplicate content trees and restrict access to those content trees?

Answer 1

Yes. You simply deny the role Language Write Right access to that language.
