Merritt Digital Preservation Repository – September 2022

September 26, 2022 Author: Eric LopatinCategories:

Merritt is a digital preservation repository from the University of California Curation Center (UC3) that enables the UC community to manage, archive, and share its valuable digital content.

Welcome to the Merritt service update for September 2022

New Content and Collections

During the month of September, we established ten new collections for UC Berkeley. These cover a wide range of subject matter, from Bancroft’s Mark Twain Notebooks and its collection regarding Land Claims in California, to the C. Hart Merriam Papers collection that focuses on Merriam’s work with Californian and other Indian tribes that took place in the early 1900s.

Digital Preservation Community

iPres took place in Glasgow, Scotland during the week of September 12th with over 600 delegates attending the conference (a majority of them in-person). Hosted by the Digital Preservation Coalition, there were dozens of talks and workshops that took place. Have a look at the program here. Strong impressions were left by presentations and a final keynote that focused on the environmental impact of digital preservation practices, the leveraging on consistent standards to promote trustworthy repositories and application of maturity models, such as the DPC Rapid Assessment Model, to organizations that have dedicated resources to digital preservation efforts.

What We’re Working On

Merritt’s Ingest and Storage services are now using Amazon FSx for OpenZFS as an intermediate storage space during the ingestion process rather than AWS EFS. Though the team is still gauging overall throughput benefits of ZFS, we’re encouraged by the initial results we’ve observed in terms of network bandwidth and speed.
