I recently started two discussion threads about German category names over at transifex.com. But since it's awfully quiet there, I'll copy them here as well:
I think that an entire category for "Sozialversicherungsnummer" (Social Security Number) is not very useful for the German version. The German Sozialversicherungsnummer is not nearly as important as an American Social Security Number. Maybe we should rename this category to "Versicherungsnummer". That way it could be used for Sozialversicherungsnummern, KFZ-Versicherungsnummern, and all other kinds of Versicherungsnummern.
Since the Passport category is translated as "Reisepass" (which is technically correct), there is currently no category for storing a German "Personalausweis" (a distinction that doesn't exist in Canada and the US). If we'd rename this category to "Personalpapiere" or something similar, it could be used for storing both Reisepässe and Personalausweise. Any thoughts?
