We are facing the same issue as we have one journal that accept articles in 3 different languages. We are desperately looking for this function to allow changes of the AUTHORS names and data appear in correspondence language when switching the language interface.
I would have thought that this logical for multilingual OJS but we found out that
Name, Username, Affiliation are in English language
Name, Username, Affiliation are in Arabic language
Submission in English
Titles, Subtitles, Abstract, Keywords, Disciplines, etc are accepting to be fill in in English and Arabic.
Submission in Arabic
Titles, Subtitles, Abstract, Keywords, Disciplines, etc are accepting to be fill in in Arabic and English.
Moreover, you can edit the Contributors names (Authors), and Edit/fill in the affiliation and Biography in Arabic and English languages.
Only the author name cannot be in two languages, but the affiliation and Biography can be.
This shortcoming is only effect the author's name. Is it because the name is used as unique key? I am not a programer but If so, what if you can develop USER AUTO ID NUMBER to make the user name fields insignificant so the number ID can be tagged in any language and show the correspondence field names for the selected language if any.
