Are there any plans to make MediaData localizable in any future release/patch?
No, nothing planned to my knowledge at least.
Okey, thank you for the information.
Nothing new on this?
It would be nice to be able to add localized properties to MediaData files, and also to be able to filter on language when doing search in Find.
The Making Waves crew has made their own implementation if you're interested: https://gregwiechec.com/2015/07/localizable-media-assets/
Seems like a nice solution, thanks for the tip!
