Internationalization of ResCarta-Web has been completed. This allows support for new languages to be very easily added with the addition of a single file containing the translations for a given language.
The Russian translation was done by a librarian from the Khabarovsk State Institute of Arts and Culture in Russia.
You can check out the demo at http://demos.rescarta.org/ResCarta-Web-ru.
You will notice that the metadata is in English. This is only because the demo data is English. A Russian user would most likely create their data in Russian.
