This article has a translation, the translation link will take you to it.
Notice that the translation can have a different tag, so even tags can be translated.
As described in the Pelican translations documentation, an article is considered a translation of a different article if
- it has the same slug metadata
- has a different lang metadata
If you want the translation to have a different filename and url than the slug in the original language, use the save_as and url metadata as this translation link shows.
