Field translation Synchronization
This module allows you to efficiently copy field translations between languages on your multilingual Drupal site. It is particularly useful for managing similar language variations, enabling you to translate content once and then distribute it to multiple related languages, with the option for subsequent customization.
If you have a multilingual site that has multiple languages for different
countries, you soon run into the issue where Columbian Spanish, Argentinian
Spanish and Mexico Spanish are similar enough that it doesn't make sense to have
3 different translations. You want to add the translation on one of those sites,
then copy it over to all the others. You want to copy it over, because you still
add some customization to the translation after copied into the country. This
module lets you bulk copy/paste from any language into any other language on a
field-by-field basis.
This project is heavily influenced by Views Bulk Edit. Many thanks to Graber and others who have faithfully maintained that project.
