What is Archivematica?
● digital preservation/curation system ● designed to maintain standards-based, long-
term access to collections of digital objects● uses a micro-services design pattern● free and open-source (AGPLv3)● supported by Artefactual Systems Inc.
What is Archivematica?
● allows users to process digital objects from ingest to access in conformance with the ISO-OAIS functional model
● creates high-quality, standards-compliant Archival Information Packages (AIP)
● provides – an architecture for implementing preservation strategies
– a framework for evaluating and implementing format policies

Preservation planning
● a two-pronged approach:– Normalization on ingest
– Preservation of the original file to support future strategies such as migration and emulation
● normalization relies on format policies based on an analysis of the significant characteristics of file formats
● A format policy indicates the actions, tools and settings to apply to a file of a particular file format (e.g. normalization to preservation and/or access format)
Archivematica format policies
● criteria for selecting default formats:● Non-proprietary● Freely available specifications● Widely used/endorsed by major repositories● No compression/lossless compression● Tools available to write and render the format
● format policies will change as community standards, practices and tools evolve.
● upcoming Format Policy Registry (FPR) will allow users to add local format policies, download defaults/ updates and monitor statistics
Video in Archivematica● Preservation Format
– FFV1/PCM in Matroska wrapper (MKV) ● FFV1 a completely lossless video codec● Matroska (pronounced maTROSHka) is an open
standard free video container format which can hold a large number of video and audio codecs
● Access Format– MPEG-1/MP2
● Normalization tool– FFmpeg
Motion JPEG 2000 (MJPEG2K)
● emerging as a preferred format for video files● great example of how FPR could be used to add
format policies● encoding JPEG2000-MXF video (added to wiki by
Misty de Meo) – can be added as default workflow to local implementtion
– can be shared via the future FPR
– statistics about normalization results recorded
– possible future default for Archivematica
