Arquivo Público e Histórico do Município de Jacareí
Jacareí launched an online guide to its municipal public and historical archive on 15 December 2021 using AtoM. The project, produced through São Paulo state's ProAC cultural programme, opened remote consultation of a mixed archive containing manuscripts, printed material, photographs, plans, maps, sound recordings and films. The municipality described the guide as its first step toward computerising access to the documentary heritage, rather than as a replacement for a named catalogue or database. The AtoM service made the archive's collection structure discoverable online and connected the municipal archive with wider Brazilian archival practice. Because the source does not describe data extraction, metadata mapping or transfer from an earlier system, this case is classified as an AtoM implementation and access project, not a legacy-system migration.
