Archivo General de la Nación (Mexico)
Mexico's Archivo General de la Nación began work with AtoM in 2021 as part of an institutional objective to design and implement a digital repository. Its first-semester 2022 self-evaluation records that technical staff reviewed standards and platform options, continued the AtoM work begun the previous year and produced a first design proposal. Digital-preservation staff were capturing information from selected fonds for loading into the platform, while weekly meetings evaluated the service and resolved questions. The report therefore documents a real but still developing pilot rather than a completed nationwide catalogue migration. It does not name the specific fonds loaded, link the AtoM work to the Archivo Histórico de Hacienda, identify a predecessor database or mention Archivematica.
