UC Libraries Digital Preservation Repository
Mass Transit Project
CDL is collaborating with the San Diego Supercomputer Center to explore large scale transfer and storage of data within the UC system in the context of digital preservation.
The 14-month project will investigate tools and methods for large scale data transfer across the network as well as storage and data replication strategies. Some UC campuses and data centers will also participate in this effort to learn how best to move many terabytes of content into the DPR.
DPR Stats
The DPR currently holds about 925 GB -- almost 150,000 objects.
The foundation of the University of California libraries digital preservation program, the Digital Preservation Repository (DPR) serves the stewardship mission of the UC libraries by providing a single shared solution for the preservation, management, and controlled dissemination of digital collections that support research, teaching, and learning. The repository provides a set of self-service interfaces that the libraries use to deposit and manage digital objects, relieving individual libraries of the burden of creating and maintaining custom digital repositories. The services and storage are based at the California Digital Library (CDL).

Get Started
The Digital Preservation Repository is currently only available to University of California libraries. When you request a DPR account, a CDL staff member will contact you to discuss the materials you want to preserve and to help you get started.Preparing Materials for the DPR

Use the DPR
There are two ways to access the DPR. See the chart below to choose the right method.
| Web Interface | Java Toolkit | |
| The web interface is the simplest option and is ideal for users with limited programming support. |
The Java Toolkit option is ideal for libraries that want to plug the DPR into their own Java programs and tailor it to meet their needs. The CDL will supply you with the Java Toolkit when you establish your DPR account.
