"The Rosetta Project is a global collaboration of language specialists and native speakers working to develop a contemporary version of the historic Rosetta Stone. Run by the Long Now Foundation, the project aims to create a survey and near-permanent archive of 1,500 languages that can enable comparative linguistic research and education and might help recover or revitalize lost languages in the future." --from the Wikipedia description of the Rosetta Project: https://en.wikipedia.org/wiki/Rosetta_Project
