Compartilhamento de dados linguísticos: da prática à infraestrutura

This dossier brings together works originated from Abralin em Cena 17 — Linguistic Data (2023), an online event organized by ABRALIN, the Sociolinguistics Working Group of ANPOLL, and the Brazilian Linguistic Diversity Platform Project. The texts address sharing, preservation, and reuse of linguistic corpora; metadata methodology and comparability across databases; and natural language processing. The papers both integrate and exemplify the Open Science culture that motivated the event, converging to demonstrate the need for a national linguistic data infrastructure for Brazil's digital sovereignty.
