General

Processing

El texto era antiguo entonces se verificó con hablantes de Norogachi que revisaran si había léxico diferente, etc.

Recommended post-processing

Si se trabaja con personas de otras comunidades tienen que normalizar los datos, es decir adaptarlos a las variaciones dialectales de la otra comunidad. Hubo una hablante de Cusarare, Guachochi que está considerado de la misma lengua y tenía dudas sobre algunas palabras.
