General description

The ability to implement preservation plans is built into Archivematica. Archivematica's primary preservation strategy is to normalize files to preservation and access formats upon ingest. The preservation formats are added to the AIP and the access formats are used to generate a DIP for upload to the access system. Note that the original files are always kept, to allow for different preservation actions in the future, such as normalization to different archival formats or emulation.

The Preservation planning tab

1. The Preservation planning tab lists formats by media type and describes their preservation and access normalization paths (figure 1).
   

   Figure 1 AIPs stored in the default AIPsStore directory in quad-UUIDs.
2. Clicking on a media type (such as Audio) takes the user to the relevant preservation plan on the Archivematica wiki.
3. Clicking on "Show" on the right-hand side opens a tab showing the normalization command. In future versions of Archivematica these will be editable for the Preservation planning tab; in Archivematica 0.8 the commands can be edited in the mysql database. Instructions for this are available at Link.
4. In the demo version of Archivematica the AIP storage directory is /sharedDirectoryStructure/www/AIPsStore/ (figure 1). In other environments it can be a remote network mounted directory.
5. The AIP directories are broken down into UUID quad directories for efficient storage and retrieval.
6. The Archival storage tab in the Archivematica dashboard consists of a table with information about the stored AIPs (figure 2). Use the up and down arrows in the column headers to sort by AIP name, size, UUID or date. Note that at the bottom of the Size column is the total size of the stored AIPs.
7. To open a copy of the AIP, click on the AIP name. You can then open or download the zipped AIP (figure 3).
8. More information on Archivematica's AIP structure and the METS/PREMIS file is available on the Archivematica wiki: see AIP structure and METS.
