For plants I need three: Russian and English common names and Latin species names. I use Russian keyword tree structure because I am Russian
and in synonyms I put English common names and Latin species name with "lat. " prefix.
Then I can use php script to filter out Russian or English keywords (because Russian and English use different letters) or Latin because of its prefix!
So, In my case before sending images to a client I need to pass files thru my php filtering script.
