Digital Preservation Community

Collaborative Good Practices for Digital Preservation in the Cloud

At iPRES 2025 the Merritt team collaborated with APTrust on a workshop regarding digital preservation practices in the cloud. The workshop involved three, rotating breakout sessions focused on preservation activities, DevOps and FinOps. Participants cycled through each breakout to discuss both specific prompts as well as their experiences with the topic at hand. During the these discussions, participants were also asked to record points of interest in a collaborative, shared “good practices” document. Post-conference, we continued to collaborate around this document which was published via UVA’s LibraOpen platform for public access. It will also be included in forthcoming iPRES proceedings. It is currently available here!

What We’re Working On

As noted in our prior update, the Merritt team is running full steam ahead on its effort to containerize the repository as a whole. We are preparing to move Merritt’s user interface web application into containers and will then proceed with moving its fixity checking (Audit) and Replication services. Please have a look at our UC3 New Year series blog post on digital preservation that reviews a sampling of the team’s upcoming efforts for 2026, including this one!
