Artefactual Systems is the lead developer of the open source applications AtoM and Archivematica. AtoM allows for standards-based archival description and access in a multilingual, multi-repository environment. Archivematica supports digital preservation workflows based on the OAIS reference model. Both applications are web-based and follow best practices like using standards and being language-agnostic. Artefactual takes a community-based approach to development and offers additional paid services while their core applications remain free and open source.
