From 1979 to 1992, El Salvador was engulfed in a bloody, political civil war, with over 75,000 civilian casualties. In the early 1990s, several NGOs and a UN Truth Commission began systematically documenting human rights atrocities perpetrated during the war, using personal testimonies, military records, and other documents. Each database was designed differently, utilizing the technologies available at the time. These files changed hands multiple times over the next 25 years, with limited accompanying documentation; information about metadata values has long been lost. Working with the UW Center for Human Rights and the Human Rights Data Analysis Group, our team developed a data management plan and an initial data dictionary for one database. Researchers ultimately hope to examine, standardize, and map fields across databases, providing a fuller picture of the human rights violations committed and supporting the efforts of surviving family members, scholars, and legal teams for truth and accountability.
