This project concerns an ongoing language documentation project covering the Mixtepec-Mixtec variety of Mixtec (iso 639-3: mix). Mixtepec-Mixtec is an Otomonguean spoken by roughly 9000-10000 people in the Juxtlahuaca district of Oaxaca, and parts of the Guerrerro and Puebla states of Mexico as well as by communities living in California, Oregon, Washington and Arkansas. Among the primary facets of the work are to: create an open source body of reusable and extensible multimedia language resources encoded in TEI XML; create multi-lingual translations (English and Spanish), annotate the content according to sound theoretical linguistic principles; use the above in order to further the knowledge of all aspects of the language itself within the fields of linguistics and lexicography by producing empirical corpus-based descriptions and analyses of various aspects of the language’s features; demonstrate and evaluate the application of encoding and description standards on a collection of lexical and knowledge resources for an under-resourced non-indo-european language. In addition to providing a lasting and reusable set of resources for the MIX language, this work also aims to make strides towards bridging the gap between lexicography, language documentation, theoretical linguistics, computational linguistics and digital humanities.
