-delting classes using the back-end disassociates terms from posts.
-
-translate:
-
-get a jskos file
-scripts/jskos2csv it
-open csv with excel
-copy table to word
-let deepL translate the word file
-copy the table from the translated file to excel
-fix wrong translations
-save as csv
-use scripts/csv2jskos to merge it with an existing jskos file
-
-this must be done for the first import
-
-it's useful to use sed to prefix classes with a letter so that
-excel leaves them alone; just undo it before calling csv2jskos
-
-nb: the scripts are imperfect, expect to fix some stuff manually.
-
-NB: some of these operations take so long that, if you're using fastCGI,
-the webserver may stop waiting for the PHP-FPM; all operations will complete,
-but you won't see the output.
-
-increase the webservers fastcgti timelimit to fix this.

-# FIXME
-
-Nota bene, the JSKOS file that can be downloaded from the GBV tends to
-contain *a lot* of errors, mostly when it comes to capitalisation and
-punctuation. You may want to correct those; if so, comma-separated
-values are probably the most convenient format for doing so.

 # Translating the Basisklassifikation
 
 Needs Polylang; taxonomy must be marked as being translated first!
