Yes, it would be very helpful to have the codelists translated and available quite soon, as they are needed by the team building our new data visualization platform.
I think it would make sense for this to become part of the normal standard upgrade process - just like e.g. documentation and guidance are revised/updated to reflect any changes in the standard. In fact, we had assumed this was already the case, given there was agreement on the need to have codelists available in multiple languages. This is how the WP-STAT proceeds as well; when changes are made to any part of the standard (like, for instance, the recent purpose codes related to country budgets), they are posted in English and French at the same time. The translation is an integral part of the upgrade process.
