About the Comparative Analysis

The Chronicles in Preservation project, funded by a 3-year grant from the National Endowment for the Humanities (NEH), has provided an evaluation of three leading technical approaches in the U.S. context (iRODS at Chronopolis, LOCKSS at MetaArchive, and Coda at University of North Texas Libraries) for institutions that want to preserve their diverse newspaper holdings in Distributed Digital Preservation (DDP) frameworks. Each of these approaches has unique features and qualities that may be well suited to particular institutions’ needs. This Comparative Analysis is intended to assist other DDP service providers in analyzing features of their own systems for preserving digital newspapers, as well as other types of digital content.

Distributed Digital Preservation is defined for the purposes of this Comparative Analysis as the use of replication, independence, and coordination to address the known threats to digital content to ensure its accessibility through time.

How to Use the Comparative Analysis

We invite other DDP systems and/or providers to consider sharing details about their own methodologies using a version of this tool, which is open for editing by request on Google Docs (see below). Transparently documenting these details will help the broader preservation community to better understand preservation infrastructures and workflows.

The information is read-only to the public. If you are interested in supplying information about your DDP system or service please contact Nick Krabbenhoeft (nick@metaarchive.org), who will add you to the list of approved contributors. Name and contact will be necessary to include with your entry. All information supplied is copyright of the respective author contributors who, by supplying such information, license their work under a Attribution-NonCommercial-NoDerivs 4.0 International License. Any of these conditions can be waived if you get permission from the copyright holder. Your fair use and other rights are in no way affected by the above.

Share Your Details

Comparative Analysis Tool

Once you have access to the tool, adding information is easy. You can edit each cell independently and take as much time as necessary to complete. Consider the value in supplying as complete a record as possible. There is a field at the top of each provider column to record the name & contact for the person completing the entry. We highly recommend that each entry be performed by an authorized representative from the system or service provider. Educopia Institute takes no responsibility for unauthorized or inaccurate entries, representations, or characterizations. If you feel someone from your institution has inaccurately supplied information about your system or service please bring it to our attention. We can work with you to get that information corrected.

Future Plans

This Comparative Analysis for Distributed Digital Preservation Frameworks is synergistic with a larger effort currently underway to document distributed digital preservation best practices. This effort is known as the DDP Frameworks Initiative. The first set of work underway in that Initiative is to create a Framework for Applying the Reference Model for an Open Archival Information System (OAIS) to Distributed Digital Preservation. You can read more about that here: http://www.metaarchive.org/ddp. A pilot version 1.0 of the Framework will be available in Spring/Summer 2014.

This Comparative Analysis instrument will be an additional layer of information and outreach that can help to further that larger set of work and expand the research base.
