Just wanted a place to add other places that do some form of multilinguality or translation:
- Wikidata has a number of places where content is multilingual:
- labels, aliases, descriptions for items and properties
- multilingual text as a value
- Lexemes have senses with multilingual glosses
- Commons has a number of multilingual contents (but I don't know much about Commons)
- Some of it uses templates where each parameter is a language (I've seen that on Meta too)
- the structured data on commons seem to have potentially multilingual values?
It would be great if we could have a more comprehensive list somewhere and see if these could be handled in a more unified manner.
