  An activity-based costing model for long-term preservation and dissemination of digital research data: the case of DANS :

  « Financial sustainability is an important attribute of a trusted, reliable digital repository. The authors of this paper use the case study approach to develop an activity-based costing (ABC) model. This is used for estimating the costs of preserving digital research data and identifying options for improving and sustaining relevant activities. The model is designed in the environment of the Data Archiving and Networked Services (DANS) institute, a well-known trusted repository. The DANS–ABC model has been tested on empirical cost data from activities performed by 51 employees in frames of over 40 different national and international projects. Costs of resources are being assigned to cost objects through activities and cost drivers. The ‘euros per dataset’ unit of costs measurement is introduced to analyse the outputs of the model. Funders, managers and other decision-making stakeholders are being provided with understandable information connected to the strategic goals of the organisation. The latter is being achieved by linking the DANS–ABC model to another widely used managerial tool—the Balanced Scorecard (BSC). The DANS–ABC model supports costing of services provided by a data archive, while the combination of the DANS–ABC with a BSC identifies areas in the digital preservation process where efficiency improvements are possible. »

  Preservation Status Of E-Resources: A Potential Crisis In Electronic Journal Preservation :
  

  « E-journals have replaced the majority of titles formerly produced in paper format. Academic libraries are increasingly dependent on commercially produced, born-digital content that is purchased or licensed. The purpose of this presentation is to share the findings of a 2CUL study that assesses the role of LOCKSS and PORTICO in preserving each institution’s e-journal collections. The 2CUL initiative is a collaboration between Columbia University Library (CUL) and Cornell University Library (CUL) to join forces in providing content, expertise, and services that are impossible to accomplish acting alone.

  Although LOCKSS is considered a successful digital preservation initiative, neither of the CULs felt that they fully understood the potential of the system for their own settings and collections. In support of this goal, a joint team was established in November 2010 to investigate various questions to assess how LOCKSS is being deployed and the implications of local practices for both CUL’s preservation frameworks. This study was seen as a high-level investigation to characterize the general landscape and identify further research questions. One of the practical outcomes was a comparative analysis of Portico and LOCKSS preservation coverage for Columbia and Cornell’s serial holdings. A key finding was that only 15-20% of the e-journal titles in the libraries’ collections are currently preserved by these two initiatives. Further analysis suggests the remaining titles fall into roughly 10 categories, with a variety of strategies needed to ensure their preservation. »

  Institutional Repositories, Long Term Preservation and the changing nature of Scholarly Publications :

  « The web offers new opportunities for scholars to publish the outcome of their research. One of these new forms is called Enhanced Publications. In an Enhanced Publication different objects and files that has a meaningful and close relation to each other are aggregated on the level of a resource map in witch not only the separate files are described, but also the relation between those files are. An example of an Enhanced Publication is a digital text publication and a dataset on which the publication is based. Preserving these compound entities in the existing infrastructures raises new issues. This article discusses these issues against the background of the Dutch long term preservation infrastructure and organisation. »

  Institutional Repositories and Digital Preservation: Assessing Current Practices at Research Libraries :

  « In spring 2010, authors from the University of Massachusetts Amherst conducted a national survey on digital preservation of Institutional Repository (IR) materials among Association of Research Libraries (ARL) member institutions. Examining the current practices of digital preservation of IR materials, the survey of 72 research libraries reveals the challenges and opportunities of implementing digital preservation for IRs in a complex environment with rapidly evolving technology, practices, and standards. Findings from this survey will inform libraries about the current state of digital preservation for IRs. »

  Preserving repository content: practical tools for repository managers :

  « The stated aim of many repositories is to provide permanent open access to their content. However, relatively few repositories have implemented practical action plans towards permanence. Repository managers often lack time and confidence to tackle the important but scary problem of preservation.
  Written by, and aimed at, repository managers, this paper describes how the JISC-funded KeepIt project has been bringing together existing preservation tools and services with appropriate training and advice to enable repository managers to formulate practical and achievable preservation plans.
  Three elements of the KeepIt project are described:
  1. The initial, exploratory phase in which repository managers and a preservation specialist established the current status of each repository and its preservation objectives;
  2. The repository-specific KeepIt preservation training course which covered the organisational and financial framework of repository preservation; metadata; the new preservation tools; and issues of trust between repository, users and services;
  3. The application of tools and lessons learned from the training course to four exemplar repositories and the impact that this has made.
  The paper concludes by recommending practical steps that all repository managers may take to ensure their repositories are preservation-ready. »

  The Dataverse Network®: An Open-Source Application for Sharing, Discovering and Preserving Data :

  « The Dataverse Network is an open-source application for publishing, referencing, extracting and analyzing research data. The main goal of the Dataverse Network is to solve the problems of data sharing through building technologies that enable institutions to reduce the burden for researchers and data publishers, and incentivize them to share their data. By installing Dataverse Network software, an institution is able to host multiple individual virtual archives, called « dataverses » for scholars, research groups, or journals, providing a data publication framework that supports author recognition, persistent citation, data discovery and preservation. Dataverses require no hardware or software costs, nor maintenance or backups by the data owner, but still enable all web visibility and credit to devolve to the data owner. »

  IISH Guidelines for preserving research data: a framework for preserving collaborative data collections for future research :

  « Our guidelines highlight the iterative process of data collection, data processing, data analysis and publication of (interim) research results. The iterative process is best analyzed and illustrated by following the dynamics of data collection in online collaboratories. The production of data sets in such large scale data collection projects, typically takes a lot of time, whilst in the meantime research may already be performed on data sub-sets. If this leads to a publication a proper citation is required. Publishers and readers need to know exactly in what stage of the data collection process specific conclusions on these data were drawn. During this iterative process, research data need to be maintained, managed and disseminated in different forms and versions during the successive stages of the work carried out, in order to validate the outcomes and research results. These practices drive the requirements for data archiving and show that data archiving is not a once off data transfer transaction or even a linear process. Therefore from the perspective of the research process, we recommend the interconnection and interfacing between data collection and data archiving, in order to ensure the most effective and loss-less preservation of the research data. »

  Designing and Implementing Second Generation Digital Preservation Services: A Scalable Model for the Stanford Digital Repository :

  « This paper describes the Stanford Digital Repository (SDR), a large scale, digital preservation system for scholarly materials. It examines the lessons-learned through over five years of development and operational experience. Building on the knowledge gained, the paper goes on to outline a new repository design and service framework, SDR 2.0, that will address some of the challenges that have emerged. Changes in the environment such as staffing levels and collaborative opportunities are also described. Finally, the paper includes observations on the general state of the preservation and repository communities, and the emergence of a new generation of systems and strategies in this space. »
