Ensuring long term access to the vast range of information required for archiving is a huge problem that organisations are slowly waking up to.

SDB Digital Preservation » Challenges

The key challenges are: Media obsolescence. Information is held on unmanaged local stores (e.g laptops, optical media, local file servers) or central stores where its value is not recognised (central file servers, tape back-ups). In each case data can be lost because the media on which it is stored becomes unreadable or is replaced.Distributed and disjointed data.

Another challenge is that information is stored but its location and value are not recorded making discovery and use very difficult. These challenges pose a significant barrier to implementing a successful digital archiving policy and must be confronted before selecting your preferred approach.

Using OAI-ORE to Transform Digital Repositories into Interoperable Storage and Services Applications. By David Tarrant, Ben O’Steen, Tim Brody, Steve Hitchcock, Neil Jefferies and Leslie Carr Introduction One of the main decisions to be made when starting a digital repository is which software to use. Currently there are a wide range of choices, including open source and proprietary systems.

Most of these choices are in active development and some have been available for nearly a decade, which represents a high degree of stability in the relatively young history of digital repositories. Not every institution creating a repository will make the right initial choice of software, however, and over time the needs of a repository may evolve.

The starting point for our work was an investigation into institutional repository (IR) preservation services by the JISC-funded Preserv 2 project [25], which wanted to find a way of effectively replicating a whole IR across any repository platform.

Library Linked Data Incubator Group: Datasets, Value Vocabularies, and Metadata Element Sets

Copyright © 2011 W3C® (MIT, ERCIM, Keio), All Rights Reserved. Abstract The mission of the W3C Library Linked Data Incubator Group, chartered from May 2010 through August 2011, has been "to help increase global interoperability of library data on the Web, by bringing together people involved in Semantic Web activities — focusing on Linked Data — in the library community and beyond, building on existing initiatives, and identifying collaboration tracks for the future. " This report on datasets, value vocabularies and metadata elements sets is a complement to the main report of the group.

Lifeshareproject Blog. Preserv-final-report1.0. Digital Preservation Service Provider Models for Institutional Repositories: Towards Distributed Services. Abstract Digital preservation can encompass a range of activities, from simple replication and storage to more complex transformation, depending on the assessed value and risk to the target content.

Digital Preservation Service Provider Models for Institutional Repositories: Towards Distributed Services

These activities require planning and, in most cases, begin with a need to know the technical format of the target content. In this case, the target is the content deposited in institutional repositories (IRs). The Preserv project [1] set out to investigate the use of The National Archives' (TNA) PRONOM-DROID service (PRONOM is the online registry of technical information; DROID is the downloadable file format identification tool) for file format identification on two pilot IRs using EPrints software, and instead produced format profiles (Preserv profiles) of over 200 repositories presented via the Registry of Open Access Repositories (ROAR).

Technological Profile. HathiTrust is intended to provide persistent and high-availability storage for deposited files. In order to facilitate this, the partnership uses a storage architecture with a rich set of features designed for fault tolerance and long-term data retention. Central to the storage architecture is the use of two synchronized instances of storage with wide geographic separation (located in data centers in Ann Arbor, MI and Indianapolis, IN) and an encrypted tape backup with 6 months of previous-version retention (located in a third data center several miles from the Ann Arbor storage instance). All data centers meet the requirements for Uptime Institute Tier II classification. All storage is physically secure, locked in racks that are accessible only to authorized IT personnel.

News: Cutting the Cord. The National Science Digital Library had ambitious goals when it started in 2000: create a massive open repository of STEM learning materials culled from projects funded by its benefactor, the National Science Foundation; then organize these materials so that they could be easily cherry-picked and used by science and math instructors, from higher ed all the way down.

News: Cutting the Cord

The NSF poured well over $100 million into the project. Just over a decade later, the science digital library is on death row. It is set to be stripped of all funds in 2012, “based in part on recent evaluation findings that point to the challenges of sustaining such a program in the face of changing technology and the ways educators now find and use classroom materials,” according to a foundation directorate issued in February. That is the meta-concern at the center of “Funding for Sustainability,” a new study by the nonprofit research group Ithaka S+R.
