Technology Responsiveness for Digital Preservation: a Model Technology Responsiveness for Digital Preservation: A Model by Nancy Yvonne McGovern Thesis submitted for the Degree of Doctor of Philosophy at University College London University College London 2009 Abstract Digital preservation may be defined as the cumulative actions undertaken by an organisation or individual to ensure that digital content is usable across generations of information technology. As technological change occurs, the digital preservation community must detect relevant technology developments, determine their implications for preserving digital content, and develop timely and appropriate responses to take full advantage of progress and minimize obsolescence. This thesis discusses the results of an investigation of technology responsiveness for digital preservation. The research produced a technology response model that defines the roles, functions, and content component for technology responsiveness. The model built on the results of an exploration of the nature and meaning of technological change and an evaluation of existing technology responses that might be adapted for digital preservation. The development of the model followed the six- step process defined by constructive research methodology, an approach that is most commonly used in information technology research and that is extensible to digital preservation research. This thesis defines the term technology responsiveness as the ability to develop continually effective responses to ongoing technological change through iterative monitoring, assessment, and response using the technology response model for digital preservation. 2 Table of contents Page Abstract 2 Table of contents 3 Acknowledgements 6 Declaration 6 List of figures 7 List of abbreviations 8 Chapter 1 Introduction 15 Section 1.1 Research Problem 15 Section 1.2 Research Questions 17 Section 1.3 Digital Preservation Terminology and Concepts 19 Section 1.4 Emergence of the Digital Preservation Community 29 Section 1.5 Extent of the Existing Technology Response 36 Section 1.6 Literature Review 45 Section 1.7 Background for the Technology Response Model 52 Section 1.8 Research Methodology 59 Section 1.9 Limitations of the Research 68 Section 1.10 Organisation of the Thesis 71 Chapter 2 A Digital Preservation Perspective on Technological Change 74 Section 2.1 Introduction 74 Section 2.2 Concepts and Characteristics of Technological Change 75 Section 2.3 Innovation and Technology Developments 81 Section 2.4 Examples for Adjusting the Scope of Interest 85 Section 2.5 Expanding the Scope of Interest 87 Section 2.6 Refining the Scope of Interest 93 Section 2.7 Prioritising Technology Developments 98 Section 2.8 Information Sources for Technology Developments 107 Section 2.9 Conclusion 114 3 Chapter 3 Adapting Technology Responses for Digital Preservation 116 Section 3.1 Introduction 116 Section 3.2 Technology Forecasting 116 Section 3.3 Technology Assessment 125 Section 3.4 Technology Transfer 129 Section 3.5 Technology Monitoring 134 Section 3.6 The Human Factor in Technological Change 146 Section 3.7 Combining Technology Responses for Digital Preservation 149 Section 3.8 Conclusion 153 Chapter 4 Technology Response Model for Digital Preservation 156 Section 4.1 Introduction 156 Section 4.2 Combining the Technology and Response Results 156 Section 4.3 Characterising Technology Responsiveness 160 Section 4.4 Components of the Technology Response Model 162 Section 4.5 Identify Stage 164 Section 4.6 Monitor Stage 167 Section 4.7 Notify Stage 171 Section 4.8 Select Stage 172 Section 4.9 Assess Stage 174 Section 4.10 Respond Stage 179 Section 4.11 Combining the Stages 182 Section 4.12 Content of the Technology Response Model 184 Section 4.13 Conclusion 186 Chapter 5 Demonstrating the Technology Response Model 188 Section 5.1 Introduction 188 Section 5.2 Identify Stage 190 Section 5.3 Monitor Stage 192 Section 5.4 Notify Stage 195 Section 5.5 Select Stage 197 Section 5.6 Assess Stage 199 Section 5.7 Respond Stage 207 Section 5.8 Consolidating Technology Response Results 209 Section 5.9 Conclusion 210 4 Chapter 6 Conclusion 212 Section 6.1 Introduction 212 Section 6.2 Revisiting the Research Questions 212 Section 6.3 Evaluating the Technology Response Model 217 Section 6.4 Implementation Considerations for the Model 220 Section 6.5 Further Research on Technology Responsiveness 228 Section 6.6 Recommendations 230 Section 6.7 Conclusion 231 Annex 1 Detailed Results from the Scope of Interest Investigation 233 Annex 2 Profiles for Technology Watch Survey 245 Bibliography 260 5 Acknowledgements My research benefitted from interactions with colleagues throughout the process.

  • Preserving Geospatial Data
    Technology Watch Report Preserving Geospatial Data Guy McGarva EDINA, University of Edinburgh Steve Morris North Carolina State University (NCSU) Greg Janée University of California, Santa Barbara (UCSB) DPC Technology Watch Series Report 09-01 May 2009 © 2009 1 Executive Summary: Geospatial data are becoming an increasingly important component in decision making processes and planning efforts across a broad range of industries and information sectors. The amount and variety of data is rapidly increasing and, while much of this data is at risk of being lost or becoming unusable, there is a growing recognition of the importance of being able to access historical geospatial data, now and in the future, in order to be able to examine social, environmental and economic processes and changes that occur over time. The geospatial domain is characterized by a broad range of information types, including geographic information systems data, remote sensing imagery, three- dimensional representations and other location-based information. The scope of this report is limited to two-dimensional geospatial data and data that would typically be considered comparable to paper maps or charts including vector data, raster data and spatial databases. There are a number of significant preservation issues that relate specifically to geospatial data, including: the complexity and variety of data formats and structures; the abundance of content that exists in proprietary formats; the need to maintain the technical and social contexts in which the data exists; and the growing importance of web services and dynamic (and ephemeral) data. Standards for geospatial metadata have been defined at both the national and international levels, yet metadata often becomes dissociated from the data, or is incorrect, non-standard in nature, or not created in the first place.

Roughly one year later, the question of how best to maintain long-term access to information held in databases remains an important one for the National Archives of the Netherlands. As a first step towards further work in this area, we carried out a review of the PLANETS case study, triggered in part by participation in the Preservation of Complex Objects Symposium 1 in London in June 2011. This document is a copy of the original PLANETS case study with added commentary to document new developments in thinking, tools and technology. At the end of this document, we have added two new sections, on the use of emulation for database preservation and the possible applications of data warehousing techniques in digital preservation. We have also added a new conclusion, briefly describing what we plan to do next in this area. 1 http://www.openplanetsfoundation.org/events/2011-06-16-pocos-london-symposium Page 1 of 15 Project: IST-2006-033789 Planets Deliverable: PA/6-D13 Project Number IST-2006-033789 Project Title Planets Title of Deliverable Case Study: Database Preservation at the National Archives of the

  • Developing Cultural Heritage Preservation Databases Based on Dublin Core Data Elements
    Developing cultural heritage preservation databases based on Dublin Core data elements Fenella G. France Art Preservation Services Tel: +1 212 722 6300 x4 [email protected] Michael B. Toth R.B. Toth Associates Tel: +1 703 938 4499 [email protected] Abstract: Preserving our cultural heritage – from fragile historic textiles such as national flags to heavy and seemingly solid artifacts recovered from 9/11 – requires careful monitoring of the state of the artifact and environmental conditions. The standard for a web-accessible textile fiber database is established with Dublin Core elements to address the needs of textile conservation. Dynamic metadata and classification standards are also incorporated to allow flexibility in recording changing conditions and deterioration over the life of an object. Dublin core serves as the basis for data sets of information about the changing state of artifacts and environmental conditions. With common metadata standards, such as Dublin Core, this critical preservation knowledge can be utilized by a range of scientists and conservators to determine optimum conditions for slowing the rate of deterioration, as well as comparative use in the preservation of other artifacts. Keywords: Preservation, cultural heritage, Dublin Core, conservation, deterioration, environmental parameters, preservation vocabularies, textiles, fiber, metadata standards, digital library. 1. Introduction Preserving our cultural heritage for future generations is a critical aspect of the stewardship of historical objects. This requires careful monitoring of the state of the artifact and environmental conditions, and standardized storage of this information to support a range of professionals who play a role in the preservation, storage and display of the artifact – including conservators, scientists, curators, and other cultural heritage professionals.

  • Significant Properties in the Preservation of Relational Databases
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Universidade do Minho: RepositoriUM Significant Properties in the Preservation of Relational Databases Ricardo Andr´ePereira Freitas Advisor: Jos´eCarlos Ramalho Department of Informatics University of Minho, Braga { Portugal [email protected], [email protected] Abstract. Relational Databases are the most frequent type of databases used by organizations worldwide and are the base of several information systems. As in all digital objects, and concerning the digital preservation of them, the significant properties (significant characteristics) must be defined so that adopted strategies are appropriate. In previous work a neutral format (hardware and software independent) | DBML | was adopted to achieve a standard format used in the digital preservation of the relational databases data and structure. In this paper we walk further in the definition of the significant properties by considering the database semantics as an important characteristic that should be also preserved. For the representation of this higher level of abstraction we are going to use an ontology based approach. We will extract the entity- relationship model from the DBML representation and we will represent it as an ontology. Key words: Digital Preservation, Significant Properties, Significant Char- acteristics, Relational Databases, Ontology, OAIS, XML, Digital Objects 1 Introduction In the current paradigm of information society more then one hundred exabytes of data are already used to support our information systems [15]. The evolution of the hardware and software industry causes that progressively more of the intellectual and business information are stored in computer platforms. The main issue lies exactly within these platforms.
