Critique of Architectures for Long-Term Digital Preservation

REA Auditado

Evolving technology and fading human memory threaten the long-term intelligibility of many kinds of documents. Furthermore, some records are susceptible to improper alterations that make them untrustworthy. Trusted Digital Repositories (TDRs) and Trustworthy Digital Objects (TDOs) seem to be the only broadly applicable digital preservation methodologies proposed. We argue that the TDR approach has shortfalls as a method for long-term digital preservation of sensitive information.

The Data Audit Framework: a toolkit to identify research assets and improve data management in research led institutions

REA Auditado

Although vast quantities of data are being created within
higher education, few institutions have formal strategies
in place for curating these research outputs in the longterm. Moreover there appears to be a lack of awareness as to exactly what data are held and whether they are being
managed. In response to these concerns the Joint Information Systems Committee (JISC) issued a call for
proposals to develop and implement a Data Audit Framework suited to the needs of the UK higher education research communities.

The Data Audit Framework: A First Step in the Data Management Challenge

REA Auditado

The Data Audit Framework provides organisations with the means to identify, locate and assess the current management of their research data assets. Armed with this information they are in a position to improve ongoing data management. In this article we share our experiences of implementing the Framework and report back on the kind of data issues researchers commonly face. We also indicate how the Framework will be further developed before being released for widespread adoption.

Building a document genre corpus: a profile of the KRYS I corpus

REA Auditado

This paper describes the KRYS I corpus, consisting of documents classified into 70 genre classes. It has
been constructed as part of an effort to automate document genre classification as distinct from topic
detection. Previously there has been very little work on building corpora of texts which have been classified
using a nontopical
genre palette. The reason for this is partly due to the fact that genre as a concept, is
rooted in philosophy, rhetoric and literature, and highly complex and domain dependent in its interpretation
([11]).

Formulating representative features with respect to document genre classification

REA Auditado

Genre classification (e.g. whether a document
is a scientific article or magazine article) is closely
bound to the physical and conceptual structure of document
as well as the level of depth involved in the text.
Hence, it provides a means of ranking documents retrieved
by search tools according to metrics other than
topical similarity. Moreover, the structural information
derived from genre classification can be used to locate
target information within the text.

Long-Term Preservation of Digital Records, Part II: A Technical Solution

REA Auditado

Part I of this review suggests that the proper entities for archival attention are patterns inherent in transmitted and stored messages. Most digital archival repository technology—what private sector enterprises call Content Management (CM) technology—has been thoroughly understood and widely deployed for more than a decade. This technology is not adequate for long-term digital preservation because it includes no mechanisms for reliably assuring authenticity and intelligibility of digital documents for 50 years or longer.

Long-Term Preservation of Digital Records, Part I: A Theoretical Basis

REA Auditado

The Information Revolution is making preservation of digital records an urgent issue. Archivists have grappled with the question of how to achieve this for about 15 years. We focus on limitations to preservation, identifying precisely what can be preserved and what cannot. Our answer comes from the philosophical theory of knowledge, especially its discussion about the limits of what can be communicated. Philosophers have taught that answers to critical questions have been obscured by "failure to understand the logic of our language".

Durable Digital Objects Rather Than Digital Preservation

REA Auditado

Long-term digital preservation is not the best available objective. Instead, what information producers and consumers almost surely want is a universe of durable digital objects—documents and programs that will be as accessible and useful a century from now as they are today. Given the will, we could implement and deploy a practical and pleasing durability infrastructure within two years. Tools for daily work can embed packaging for durability without much burdening their users.

Economics and Engineering for Preserving Digital Content

REA Auditado

The keynote address of ECDL 2007 suggests that progress towards practical long-term digital
preservation is stalled. The current article responds by sketching how a modest software development
team could implement and deploy a previously described conceptual solution, Trustworthy Digital Object
(TDO) methodology, for the technical component of digital preservation. It emphasizes scholarly and
cultural digital content, but could be extended to discuss bureaucratic records. Curators cannot afford unique technology, but must exploit marketplace offerings.
