Three-dimensional scanning as a means of archiving sculptures

Thesis (M. Tech. Design technology) -- Central University of Technology, Free State, 2011This dissertation outlines a procedural scanning process using the portable ZCorporation ZScanner® 700 and provides an overview of the developments surrounding 3D scanning technologies; specifically their application for archiving Cultural Heritage sites and projects. The procedural scanning process is structured around the identification of 3D data recording variables applicable to the digital archiving of an art museum’s collection of sculptures. The outlining of a procedural 3D scanning environment supports the developing technology of 3D digital archiving in view of artefact preservation and interactive digital accessibility. Presented in this paper are several case studies that record 3D scanning variables such as texture, scale, surface detail, light and data conversion applicable to varied sculptural surfaces and form. Emphasis is placed on the procedural documentation and the anomalies associated with the physical object, equipment used, and the scanning environment. In support of the above, the Cultural Heritage projects that are analyzed prove that 3D portable scanning could provide digital longevity and access to previously inaccessible arenas for a diverse range of digital data archiving infrastructures. The development of 3D data acquisition via scanning, CAD modelling and 2D to 3D data file conversion technologies as well as the aesthetic effect and standards of digital archiving in terms of the artwork – viewer relationship and international practices or criterions of 3D digitizing are analysed. These projects indicate the significant use of optical 3D scanning techniques and their employ on renowned historical artefacts thus emphasizing their importance, safety and effectiveness. The aim with this research is to establish that the innovation and future implications of 3D scanning could be instrumental to future technological advancement in an interdisciplinary capacity to further data capture and processing in various Cultural Heritage diagnostic applications

A Public Record at Risk: The Dire State of News Archiving in the Digital Age

This research report explores archiving practices and policies across newspapers, magazines, wire services, and digital-only news producers, with the aim of identifying the current state of archiving and potential strategies for preserving content in an age of digital distribution. Between March 2018 and January 2019, we conducted interviews with 48 individuals from 30 news organizations and preservation initiatives. What we found was that the majority of news outlets had not given any thought to even basic strategies for preserving their digital content, and not one was properly saving a holistic record of what it produces. Of the 21 news organizations in our study, 19 were not taking any protective steps at all to archive their web output. The remaining two lacked formal strategies to ensure that their current practices have the kind of longevity to outlast changes in technology. Meanwhile, interviewees frequently (and mistakenly) equated digital backup and storage in Google Docs or content management systems as synonymous with archiving. (They are not the same; backup refers to making copies for data recovery in case of damage or loss, while archiving refers to long-term preservation, ensuring that records will still be available even as formatting and distribution technologies change in the future.) Instead, news organizations have handed over their responsibilities as public stewards to third-party organizations such as the Internet Archive, Google, Ancestry, and ProQuest, which store and distribute copies of news content on remote servers. As such, the news cycle now includes reliance on proprietary organizations with increasing control over the public record. The Internet Archive aside, the larger issue is that their incentives are neither journalistic nor archival, and may conflict with both. While there are a number of news archiving initiatives being developed by both individuals and nonprofits, it is worth noting that preserving digital content is not, first and foremost, a technical challenge. Rather, it’s a test of human decision-making and a matter of priority. The first step in tackling an archival process is the intention to save content. News organizations must get there. The findings of this study should be a wakeup call to an industry fond of claiming that democracy cannot be sustained without journalism, one which anchors its legitimacy on being a truth and accountability watchdog. In an era where journalism is already under attack, managing its record and future are as important as ever. Local, independent, and alternative news sources are especially at risk of not being preserved, threatening to leave critical exclusions in a record that will favor dominant versions of public history. As the sudden Gawker shutdown demonstrated in 2016, content can be confiscated and disappear instantly without archiving practices in place

A framework for digital archiving at selected public universities in Kenya.

Doctoral Degree. University of KwaZulu-Natal, Pietemaritzburg.Archival records are knowledge assets that preserve the overall historical scholarship, memory and identity of organisations and institutions of higher learning. The rapid transformations witnessed on the digital landscape today have led to the increased generation of digital records, prompting the growing interest by universities to adopt sustainable digital archiving implementations to ensure the continued access of archives. This research investigated digital archives management practices in selected public universities in Kenya. The objective of the study was to develop a digital archiving framework for the archival repositories at the institutions. To achieve this objective, the study sought to answer five research questions which were: what is the state of digital archiving readiness of public universities in Kenya? How are digital archives identified and administered in Kenyan public universities? Which legal and regulatory frameworks govern digital archives management in Kenyan public universities? Which risk factors are digital archives exposed to in these universities? What possible solutions can be adopted to mitigate the identified risks and support sustainable digital archiving implementations in Kenyan public universities? The study subscribed to the pragmatic school of thought which formed the basis for adopting a mixed methods approach that prompted the use of qualitative and quantitative methodologies, with a qualitative priority. The study was underpinned by the records continuum (RC) model, Open Archival Information System (OAIS) Reference model and the Archives and Records Management Association (ARMA) Records Management Maturity model which were triangulated to coin a conceptual framework for the study. The study adopted a multiple-case (embedded) design using cross-sectional survey. Six universities were purposively selected from 23 fully accredited public universities in Kenya namely: the University of Nairobi, Jomo Kenyatta University of Agriculture and Technology, Moi, Kenyatta, Maseno and Egerton Universities. Purposive sampling was used to select a sample of 205 respondents comprising of deputy vice-chancellors, finance officers, legal officers, ICT directors, archivists, records managers, records officers, ICT staff and administrative staff. Questionnaires were administered to 169 respondents; 36 participants were targeted for interviews, and document review was used to confirm the data. Quantitative data was analysed using Statistical Package for the Social Sciences (SPSS) and presented using inferential and descriptive statistics. Qualitative data was analysed thematically using NVivo and presented using charts, graphs and tables as applicable. The key findings suggested that public universities in Kenya have not attained the desired optimal state of readiness for digital archiving. This was evidenced by the absence of functional archival repositories in five of the universities, insufficient harnessing of the available ICTs for d-archiving, inadequate skilled and competent staff, low prioritization for the education and training of recordkeeping staff and absence of dedicated budgets for records and archives management functions in the institutions. Furthermore, there were no formal processes guiding the lifecycle management of digital records and the generated metadata. The situation was exacerbated by weak and/or non-existent legal and regulatory frameworks for recordkeeping at national and institutional levels. Subsequently, digital records were exposed to risks at various stages of their lifecycle which included records technology risks, legal and regulatory risks, administrative risks and records control risks. The risks further occasioned a cocktail of challenges that called for urgent interventions. The overall conclusion of the study was that even though the institutions have instigated various approaches and strategies to mitigate the identified risks, a lot needed to be done to improve the state of digital archives management in the universities. Taking into consideration the study findings, this research recommends a framework for digital archiving that brings into perspective a collaborative approach, whose core focus is to enhance d-archiving practices in archival repositories of collaborating institutions

Invest to Save: Report and Recommendations of the NSF-DELOS Working Group on Digital Archiving and Preservation

Digital archiving and preservation are important areas for research and development, but there is no agreed upon set of priorities or coherent plan for research in this area. Research projects in this area tend to be small and driven by particular institutional problems or concerns. As a consequence, proposed solutions from experimental projects and prototypes tend not to scale to millions of digital objects, nor do the results from disparate projects readily build on each other. It is also unclear whether it is worthwhile to seek general solutions or whether different strategies are needed for different types of digital objects and collections. The lack of coordination in both research and development means that there are some areas where researchers are reinventing the wheel while other areas are neglected. Digital archiving and preservation is an area that will benefit from an exercise in analysis, priority setting, and planning for future research. The WG aims to survey current research activities, identify gaps, and develop a white paper proposing future research directions in the area of digital preservation. Some of the potential areas for research include repository architectures and inter-operability among digital archives; automated tools for capture, ingest, and normalization of digital objects; and harmonization of preservation formats and metadata. There can also be opportunities for development of commercial products in the areas of mass storage systems, repositories and repository management systems, and data management software and tools.

IPEA: the digital archive use case

Now is the time to migrate tape-based media archives to digital file-based archives for television broadcasters. These archives not only address the issue of tape-deterioration, they also create new possibilities for opening up the archive. However, the switch from tape-based to file-based is something only the very big television broadcasters can manage individually. Outer- broadcasters should work together to accomplish this task. In the Flemish part of Belgium, the two largest broadcasters in Flanders, namely the commercial broadcaster VMMa and the public broadcaster VRT, the television facilities supporting company Videohouse, and different university research groups associated with the Interdisciplinary Institute for Broadband Technology joined forces and started the "Innovative Platform on Electronic Archiving" project. The goal of this project is to develop common standards for the exchange and archiving of audio-visual data. In this paper, we give a detailed overview of this project and its different research topics
