Digital Materiality: Preserving Access to Computers as Complete Environments

(2009)

This paper addresses a particular domain within the sphere of activity that is coming to be known as personal digital papers or personal digital archives. We are concerned with contemporary writers of belles-lettres (fiction, poetry, and drama), and the implications of the shift toward word processing and other forms of electronic text production for the future of the cultural record, in particular literary scholarship. The urgency of this topic is evidenced by the recent deaths of several high-profile authors, including David Foster Wallace and John Updike, both of whom are known to have left behind electronic records containing unpublished and incomplete work alongside of their more traditional manuscript materials. We argue that literary and other creatively-oriented originators offer unique challenges for the preservation enterprise, since the complete digital context for individual records is often of paramount importance—what Richard Ovenden, in a helpful phrase (in conversation) has termed “the digital materiality of digital culture.” We will therefore discuss preservation and access scenarios that account for the computer as a complete artifact and digital environment, drawing on examples from the born-digital materials in literary collections at Emory University, the Harry Ransom Center at The University of Texas at Austin, and the University of Maryland.

A Translation Layer to Convey Preservation Metadata

(2009)

The long term preservation is a responsibility to share with other organizations, even adopting different preservation methods and tools. The overcoming of the interoperability issues, by means of the achievement of a flawless exchange of digital assets to preserve, enables the feasibility of applying distributed digital preservation policies. The Archives Ready To AIP Transmission a PREMIS Based Project (ARTAT-PBP) aims to experiment with the adoption of a common preservation metadata standard as interchange language in a network of cooperating organizations that need to exchange digital resources with the mutual objective of preserving them in the long term.

Into the Archive: Potential and Limits of Standardizing the Ingest

(2009)

The ingest and its preparation are crucial steps and of strategical importance for digital preservation. If we want to move digital preservation into the mainstream we have to make them as easy as possible. The aim of the NESTOR guide "Into The Archive" is to help streamlining the planning and execution of ingest projects. The main challenge for such a guide is to provide help for a broad audience with heterogeneous use cases and without detailed background knowledge on the producer side. This paper will introduce the guide, present first experiences and discuss the challenges.

Towards Interoperable Preservation Repositories (TIPR)

(2009)

TIPR, Towards Interoperable Preservation Repositories, is a project funded by the Institute of Museum and Library Services to create and test the Repository eXchange Package (RXP). The package will make it possible to transfer complex digital objects between dissimilar preservation repositories. For reasons of redundancy, succession planning and software migration, such repositories must be able to exchange copies of archival information packages with each other. Every different repository design, however, describes and structures its archival packages differently. Therefore each type produces dissemination packages that are rarely understandable or usable as submission packages by other repositories. The RXP is an answer to that mismatch. Other solutions for transferring packages between repositories focus either on transfers between repositories of the same type, such as DSpace-to-DSpace transfers, or on processes that translate a specific dissemination format into a specific submission package. Rather than build translators between many dissimilar repository types, the TIPR project has defined a standards-based package of metadata files that can act as an intermediary information package, the RXP, a lingua franca all repositories can read and write. In this paper we present the assumptions and principles underlying the TIPR concept of repository-to-repository exchange, and proceed to describe three aspects of the TIPR project: the RXP format itself; the tests we are conducting to prove and improve the use of the RXP; and finally, issues that have arisen in the course of the project so far.

Born Broken: Fonts and Information Loss in Legacy Digital Documents

(2009)

For millions of legacy documents, correct rendering depends upon resources such as fonts that are not generally embedded within the document structure. Yet there is significant risk of information loss due to missing or incorrectly substituted fonts. In this paper we use a collection of 230,000 Word documents to assess the difficulty of matching font requirements with a database of fonts. We describe the identifying information contained in common font formats, font requirements stored in Word documents, the API provided by Windows to support font requests by applications, the documented substitution algorithms used by Windows when requested fonts are not available, and the ways in which support software might be used to control font substitution in a preservation environment.

Mainstreaming Preservation through Slicing and Dicing of Digital Repositories: Investigating Alternative Service and Resource Options for ContextMiner Using Data Grid Technology

(2009)

A digital repository can be seen as a combination of services, resources, and policies. One of the fundamental design questions for digital repositories is how to break down the services and resources: who will have responsibility, where they will reside, and how they will interact. There is no single, optimal answer to this question. The most appropriate arrangement depends on many factors that vary across repository contexts and are very likely to change over time. This paper reports on our investigation and testing of various repository "slicing and dicing" scenarios, their potential benefits, and implications for implementation, administration, and service offerings. Vital considerations for each option (1) efficiencies of resource use, (2) management of dependencies across entities, and (3) the repository business model most appropriate to the participating organizations.

Preserving the Digital Memory of the Government of Canada: Influence and Collaboration with Records Creators

(2009)

Library and Archives Canada has a wide mandate to preserve and provide access to Canadian published heritage, records of national significance, as well as to acquire the records created by the Government of Canada, deemed to be of historical importance. To address this mandate, Library and Archives Canada has undertaken the development of a digital preservation infrastructure covering policy, standards and enterprise applications which will serve requirements for ingest, metadata management, preservation and access. The purpose of this paper is to focus on the efforts underway to engage digital recordkeeping activities in the Government of Canada and to influence and align those processes with LAC digital preservation requirements. The LAC strategy to implement preservation considerations early in the life cycle of the digital record is to establish a mandatory legislative and policy framework for recordkeeping in government. This includes a Directive on Recordkeeping, Core Digital Records Metadata Standard for archival records, Digital File Format Guidance, as well as Web 2.0 and Email Recordkeeping Guidelines. The expected success of these initiatives, and collaborative approach should provide a model for other digital heritage creators in Canada.

Lessons Learned: Moving a Digital Preservation Network from Project Organization to Sustainability

(2009)

nestor, the German network of expertise in digital preservation started as a time-limited project in 2003. Besides the establishment of a network of expertise with an information platform, working groups, and training opportunities, a central goal of the project phase was to prepare a sustainable organization model for the network's services. In July 2009, nestor transformed into a sustainable organization with 6 of the 7 project partners and 2 additional organizations entering into a consortium agreement. The preparation of the sustainable organization was a valuable experience for the project partners because vision and mission of the network were critically discussed and refined for the future organization. Some more aspects were identified that also need further refinement in order to make nestor fit for the future. These aspects shall be discussed in the paper.
