Many languages are being lost as smaller populations disappear in the face of the encroaching mega-cultures of our time, and numerous documentation projects have recently been initiated in an attempt to preserve as much linguistic and cultural information as possible. This response to the threat of language attrition can only be applauded, but it has also drawn attention to the need for more information about optimal formats for digital documentation. Irreplaceable language documentation is often being stored in digital formats vulnerable to hardware and software obsolescence. Moreover, the heterogeneity of formats currently in use limits the accessibility and repurposing of the data.
