Audiovisual preservation strategies, data models and value-chains

This is a report on preservation strategies, models and value-chains for digital file-based audiovisual content. The report includes: (a)current and emerging value-chains and business-models for audiovisual preservation;(b) a comparison of preservation strategies for audiovisual content including their strengths and weaknesses, and(c) a review of current preservation metadata models, and requirements for extension to support audiovisual files

BlogForever: D3.1 Preservation Strategy Report

This report describes preservation planning approaches and strategies recommended by the BlogForever project as a core component of a weblog repository design. More specifically, we start by discussing why we would want to preserve weblogs in the first place and what it is exactly that we are trying to preserve. We further present a review of past and present work and highlight why current practices in web archiving do not address the needs of weblog preservation adequately. We make three distinctive contributions in this volume: a) we propose transferable practical workflows for applying a combination of established metadata and repository standards in developing a weblog repository, b) we provide an automated approach to identifying significant properties of weblog content that uses the notion of communities and how this affects previous strategies, c) we propose a sustainability plan that draws upon community knowledge through innovative repository design

DRIVER Technology Watch Report

This report is part of the Discovery Workpackage (WP4) and is the third report out of four deliverables. The objective of this report is to give an overview of the latest technical developments in the world of digital repositories, digital libraries and beyond, in order to serve as theoretical and practical input for the technical DRIVER developments, especially those focused on enhanced publications. This report consists of two main parts, one part focuses on interoperability standards for enhanced publications, the other part consists of three subchapters, which give a landscape picture of current and surfacing technologies and communities crucial to DRIVER. These three subchapters contain the GRID, CRIS and LTP communities and technologies. Every chapter contains a theoretical explanation, followed by case studies and the outcomes and opportunities for DRIVER in this field

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

Access Interfaces for Open Archival Information Systems based on the OAI-PMH and the OpenURL Framework for Context-Sensitive Services

In recent years, a variety of digital repository and archival systems have been developed and adopted. All of these systems aim at hosting a variety of compound digital assets and at providing tools for storing, managing and accessing those assets. This paper will focus on the definition of common and standardized access interfaces that could be deployed across such diverse digital respository and archival systems. The proposed interfaces are based on the two formal specifications that have recently emerged from the Digital Library community: The Open Archive Initiative Protocol for Metadata Harvesting (OAI-PMH) and the NISO OpenURL Framework for Context-Sensitive Services (OpenURL Standard). As will be described, the former allows for the retrieval of batches of XML-based representations of digital assets, while the latter facilitates the retrieval of disseminations of a specific digital asset or of one or more of its constituents. The core properties of the proposed interfaces are explained in terms of the Reference Model for an Open Archival Information System (OAIS).Comment: Accepted paper for PV 2005 "Ensuring Long-term Preservation and Adding Value to Scientific and Technical data" (http://www.ukoln.ac.uk/events/pv-2005/

The Transformation Of Archival Philosophy And Practice Through Digital Art

In many ways, digital practices have precipitated remarkable changes in the global accessibility of art. However, the digital revolution has also radically influenced the conservation processes surrounding art, including archiving, preserving, and remembering. This paper explores the conservation of digital (or “variable media”) artworks for the future benefit of culture, with particular peference to creators and viewers of art, as well as participants in interactive artworks. More specifically, this paper focuses on the philosophical and technical approaches adopted by creators, conservators, and philosophers involved in the preservation of variable media artworks. Issues of programming, interoperability between archival systems, and enhanced public access increasingly inform the design of digital archives. Indeed, the continuously shifting technological landscape—marked by the centrality of digital technologies to everyday life—problematizes the preservation of digital art through mainstream museological paradigms. Part of this analysis of digital art conservation will be drawn from the archival philosophies of Boris Groys and Rick Prelinger
