The QDA has published a new dataset entitled ‘Sociolinguistics of the Caquetá-Putumayo River Basins Dataset.’ It is based on genealogical data from seven Indigenous groups across three language families—Witotoan (Murui-Muina, encompassing two varieties: Murui and Mɨnɨka; Ocaina; Nonuya), Boran (Bora; Muinane), and Arawak (Resígaro)—as well as one linguistic isolate, Andoke, in the Caquetá-Putumayo River Basins of Colombia. Data was collected during fieldwork conducted in Leticia, Colombia, in 2024 by linguist Dr. Katarzyna I. Wojtylak under the SONATA 16 funding scheme of the (Polish) National Science Centre (NCN).
The dataset contains individual genealogical information, as well as data on familial relationships, marital ties, and linguistic repertoires. It is part of the cross-disciplinary project ‘Social Limits of Languages: The Dynamics of Contact in Northwest Amazonia,’ which aims to develop a framework for analysing diffusion patterns in language contact scenarios among the Indigenous languages of the Caquetá-Putumayo region.
