PREMIS in METS in Archivematica
Sarah Romkey, Artefactual SystemsPREMIS Implementation FairiPRES 2016
Archivematica in brief● Archivematica is a digital preservation system which
bundles together many open-source tools, and handshakes with others
● Archivematica is not a repository or a place to store digital objects
● But it is a place to process and package digital objects and collect technical/rights metadata (in PREMIS, of course!)
● Archivematica creates AIPs and DIPs and stores metadata in a PREMIS in METS file in the AIP and DIP.
● Archivematica is free and open-source.
“The METS file is the AIP.”- Marco Klindt, Zuse Institute Berlin, speaking at the recent Archivematica Camp
PREMIS events in Archivematica
● Ingestion● Message digest calculation● Fixity check● Name cleanup● Unpacking● Virus scan● Format identification● Validation● Normalization● Compression
PREMIS agents in Archivematica
● Institution
● Logged-in user
● Digital preservation system
● Soon: external agents (more later)

Development in Archivematica
● Institutions propose development projects (usually to Artefactual Systems)
● New features are rolled into the software when released.● Most new features include at least a consideration of
how it will impact the PREMIS and/or METS
Example 1: AIP re-ingest
● To be released in Archivematica 1.6 (some implementation in 1.5)
● Ability to take an AIP in archival storage and send it back to Archivematica to re-do preservation tasks
● PREMIS and METS is versioned to reflect the re-ingestion event as well as any updated tool output.
Example 2: New tool integration
● In an upcoming version of Archivematica, we’ll be integrating MediaConch as a validation tool.
● New tools mean new tool output, which means new PREMIS!
● MediaConch will facilitate two kinds of validation events:○ Validation of the files against the file specification
○ Validation against a local policy
Example 3: Dataverse as an agent
● We developed a proof of concept integration with the research data tool Dataverse
● Dataverse creates derivative files out of certain file types for purposes of analysis and display. The study can then be exported as a zipped package, which can be ingested into Archivematica
● We wanted to reflect the fact that some of the files were created by Dataverse as a software agent.
Example 4: Improving A/V handling
● Currently, Archivematica models objects down to the level of the file.
● With the introduction of MediaConch, we’re interested in modeling down to bitstreams to show the different tracks/stream within an a/v file.
