Based on #1498634: [meta] Define revision/translation SQL schema for core entities (no patch) there should be a new schema for both taxonomy. See #1498674: Refactor node properties to multilingual for an ongoing conversion. Postponed on #1818560: Convert taxonomy entities to the new Entity Field API.
Retitle based on #1658712: Refactor test_entity schema to be multilingual. Marking postponed on #1691952: Make EntityFieldQuery work with multilingual properties.
#1691952: Make EntityFieldQuery work with multilingual properties is in.
Actually this is postponed to #1818560: Convert taxonomy entities to the new Entity Field API.
One more D8Mi tag.
Issue from #4 is in, so unpostponing.
Anything left here?
Yeah, everything. You cannot translate a taxonomy label ATM in Drupal 8. At least these are NG entities. Same are menu items. They are not even NG.
@Gabor, please update issue summary with proposed solution. I'll attack this on devDays
This would apply the same property changes like #1498674: Refactor node properties to multilingual.
Update. Vocabularies are not content entities anymore.
