Merritt Digital Preservation Repository – November 2023
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 November 2023
New Content and Collections
Upcoming UCSF Library Collections
Last year, UCSF Archives & Special Collections announced that “it was awarded a grant by the National Historical Publications and Records Commission (NHPRC) in support of the project titled, Pioneering Child Studies: Digitizing and Providing Access to Collection of Women Physicians who Spearheaded Behavioral and Developmental Pediatrics.” In the coming weeks, five new collections will be created in Merritt to preserve the archival content associated with this project. Access to these collections is provided through Calisphere.
As during October, this month we’ve continued to establish new Nuxeo-to-Merritt direct deposits for UC Riverside Library. The contents of over a dozen new collections have ingested. These include many Library Special Collections and University Archives holdings, as well several from the Water Resources Collections & Archives.
Digital Preservation Community
A new Climate Watch Working Group is being launched by the NDSA! The group will “will scan and report on the most recent literature, news, and reports related to climate change and its impact on digital preservation.” Per its page on the NDSA website, the group’s goals include:
- Producing regular annotated bibliographies on recent literature, news, and reports related to climate change and its impact on digital preservation
- Creating and adding to an ongoing list of potential risks climate change poses to digital preservation work
- Creating and adding to lists of core climate change information resources to get a solid grounding in the issue, help with future projections, and lobby for preservation resources
What We’re Working On
The Merritt team is continuing its work on a prototype that allows for the introspection of the contents of individual collections in terms of file types, objects and object metadata. A limited number of objects from each of Merritt’s collections has now been loaded into the prototype and can be reviewed based on a number of factors, including but not limited to:
- Classifying different types of metadata
- Highlighting the presence and absence of object-level metadata
- Identifying and categorizing the composition of certain objects
- Identifying file extension to MIME type mismatches, where the application of characterization tools such as DROID and JHOVE is beneficial for further investigation.
We’re excited to share this work with campus partners in the upcoming weeks.
