Migration and emulation

Archivematica maintains the original format of all ingested files to support migration and emulation preservation strategies.

Normalization

Archivematica's primary preservation strategy is to normalize files to preservation and access formats upon ingest. The choice of access formats is based on the ubiquity of viewers for the file format. Archivematica's preservation formats are all open standards. Additionally, the choice of preservation format is based on community best practices, availability of open-source normalization tools, and an analysis of the significant properties for each media type.
