I would think that the particular rights for different languages are going to differ, based on a lot of different factors. Tragically, there are languages that are beyond the point of no return, in a sense, if they're down to a handful of speakers. There may be value in preserving and digitizing those languages, but there's not going to be an ability to save and revitalize those languages in the same way that there is for a language that has the possibility of being a vibrant language of life for communities.
