Greenstone doesn't have very good support for multilingual metadata at
the moment.

Here are a couple of suggestions to achieve what you want:

1. have three different metadata elements, one per language. eg
dc.SubjectFrench, dc.SubjectEnglish, dc.SubjectGerman. Assign each
metadata to each document, then build separate classifiers on each one
(classify Hierarchy -metadata dc.SubjectFrench, etc.).

2. Create three hierarchy files, one for each language (see Section 2.2
in developers guide for format).
Each line is like
id position value
Create the three files the same, but with different values. then you
only need to assign the id as dc.Subject metadata (language independent)

e.g. in dc.Subject.en.txt
1 1 Animals
1.1 1.1 Duck
...

and dc.Subject.fr.txt
1 1 Animaux
1.1 1.1 Canard
...

In this case the id is the same as the position, so for doc1, the
dc.Subject metadata will be 1.1. You only need to add one piece of
metadata for each document.
Build Hierarchy classifiers on each file
(classify Hierarchy -metadata dc.Subject -hfile dc.Subject.en.txt, etc.)

Obviously the second method is better if you have a controlled vocab and
you know what it will be at the start.

By default, both these methods will result in three subject buttons. You
will need to modify the navigation bar to link to the different
classifiers based on the interface language.
We can help you do this when you get to that stage.

I hope this helps,
Regards,
Katherine
