This list is horribly outdated and only covers apps that where available when modeltranslation was initially developed. A more complete list can be found at djangopackages.com.
A library providing support for multilingual content in Django models.
It is not possible to reuse existing models without modifying them.
A much simpler version of the above django-multilingual.
It works very similiar to the django-multilingual approach.
Django’s field that stores labels in more than one language in database.
This approach uses a specialized Field class, which means one has to change existing models.
This app utilizes a new approach to multilingual models based on the same concept the new admin interface uses. A translation for an existing model can be added by registering a translation class for that model.
This is more or less what modeltranslation does, unfortunately it is far from being finished.
