dpc_200

Significant properties are essential characteristics of a digital object which must be preserved over time for the digital object to remain accessible and meaningful. Proper understanding of the significant properties of digital objects is critical to establish best practices and helps answer the fundamental question related to digital preservation: what to preserve?


The importance of significant properties has been highlighted by a number of notable digital preservation initiatives in recent years. These include a range of projects funded by the Joint Information Systems Committee (JISC) and the European Union, in which work has been undertaken to investigate the factors affecting decisions on significant properties, to establish generic models for determining them, to develop tools and services for describing and extracting them, or simply to understand complex digital object types, using the concept of significant properties as a starting point.

JISC, the British Library and the Digital Preservation Coalition (DPC) are organising a joint workshop on 7th April at the British Library Conference Centre. The intention is to bring together the relevant projects and report on progress to date.

PDF should be used to preserve information for the future

Added on 1 April 2008

Good news the already popular PDF file format adopted by consumers and business alike is one of the most logical formats to preserve today's electronic information for tomorrow.

According to the latest report released today by the Digital Preservation Coalition (DPC), Portable Document Formats (PDF) is one of the best file formats to preserve electronic documents and ensure their survival for the future.  This announcement will allow information officers to follow a standardised approach for preserving electronic documents.

Information management and long-term preservation are major issues facing consumers and businesses in the 21st Century.  This report is one of a series where The Digital Preservation Coalition (DPC) aims to think about and address the challenges facing us.

JPEG 2000 a great step forward for the archival community

Added on 1 February 2008

The Digital Preservation Coalition has examined JPEG 2000 in a report published today.  The report concludes that JPEG 2000 represents a great stride forward for the archival community.  The format now allows for greater compression rates and a recompression rate that is visually lossless.

The findings come as the Digital Preservation Coalition launch its latest 'Technology Watch Report' written by Dr. Robert Buckley, a Research Fellow with Xerox, 'JPEG 2000 - a practical digital preservation standard?'.  The report looks in-depth at the new format and the challenges it has to cope with.  JPEG 2000 is widely used to collect and distribute a variety of images from geospatial, medical imaging, digital cinema, and image repositories to networked images. Interest in JPEG 2000 is now growing in the archival and library sectors, as institutions look for more efficient formats to store the results of major digitisation programmes.

Background

The Digital Preservation Coalition (DPC), now in its sixth year, seeks to be a proactive membership organization fostering joint action to address the urgent challenges of securing the preservation of digital resources in the UK.

At the start of the new chapter in its history, the DPC would like to hear from its members and to provide them with an opportunity to shape its next, hopefully equally successful and productive, phase. So please do attend this event which will go some way to inform DPC activities and priorities.

About the Day

The morning session will comprise of presentations from the five short-listed DP Award projects. This will provide you with an opportunity to learn more about the diverse and fascinating projects that were showcased at the Conservation Awards ceremony in September. We will also hear the Judges' perspective into how they evaluated the projects. You may even pick up some tips for the 2009 DP Awards!

http://www2.digitalpreservationcoalition.co.uk/advocacy/2007-shortlist.html

This session will be chaired by Kevin Ashley, the Chair of the Judging Panel.

After a nutritious lunch and an initial briefing you will break up into groups to focus on your selected topics. We will endeavour to ensure that you are assigned to your preferred group but we cannot always guarantee this and indeed may have to assign you to another group. There will however be an opportunity to contribute views on all issues that will be covered during the day. Full details of your group allocation will be sent to you before the event.

The key recommendations, comments, issues which arise from the discussion will be shared with other participants through a 'speed reporting' session (more about this on the day) followed by the final summing up of all those 'big ideas'.

Breakout Group Themes

The following are the themes which the groups will consider. The bullet points are merely suggestions to kick start the discussions - you may wish to consider other issues within your area - so please do feel free to! Further details will be provided before the event. Please indicate your preferences for the groups, in 1-5 order where (1) is your preferred option.

  1. 'Top 5' for 2008 - Planning for the Near Future:

    1. Consider what are the most (5) important issues in the digital landscape over the coming year

DPC/BL Joint JPEG 2000 Workshop

bl-logo

Introduction

The JPEG2000 image compression technique has been cited by experts as a new archiving format for digital images. It is both a preservation and delivery format, and has been seen as a possible alternative to the TIFF format which most institutions use as a long-term archiving standard. Produced by both imaging experts and the Joint Photographic Experts Group, it is now a recognised ISO standard. The standard JPEG file format which is so widely in use is not yet an ISO standard.

JPEG 2000 allows a wide range of uses and can support a wide range of formats and multiple resolutions. It can also offer both lossy and lossless compression modes. Most importantly it is a flexible file format which allows metadata to be built in to the file, a vital element of the digital preservation process.

However, the standard is not yet widely in use and there is as yet no native support for it in internet browsers. More investigation and practical implementations of the standard are yet to be seen but it could be used as a potential archival standard.

The workshop

This forum will look more into the details of the standard and expert speakers who are familiar with the standard or have implemented it will share their experiences. The forum will also include industry experts to talk about the creation of the file formats. Delegates will learn about the benefits of the standard, especially with regard to digital preservation and whether it is worth implementing it within their own institutions as an image storage format. Guest speakers include Bill Comstock, Harvard College Library, Christoph Becker, Vienna University of Technology, Manfred Thaller, Cologne University and Jim King, Adobe.

Who should attend the workshop?

Digital Repository Developers, Library and Archives professionals, Digital Preservation (technology watchers) future trends, Information Managers (public sector) and anyone with large numbers of images within their institutions or companies.

Cost of the workshop is £60 for DPC members and £100 for non members

Programme

The workshop will be chaired by Professor Roger James, Head of Digital Library Infrastructure, British Library.

Article on Overview of E-journal Archiving and Preservation Workshop, UKSG, Serials 20 (3) November 2007

Overview and Presentations

The DPC, The British Library and JISC held a 1 day workshop looking at the issue of e-journal archiving and preservation. The workshop brought together international stakeholders from the information world, including publishers, librarians and representatives from archiving solution providers. The day was chaired by Hazel Woodward of Cranfield University and provided an opportunity to review what initiatives are currently in place and what more developments are needed.

To open PDFs you will need Adobe Reader

The first morning session saw Anne Kenney (PDF 519KB) of Cornell University provide an overview of the e-journal archiving landscape, drawing on work that was done in 2006 to pull together the opinions of library directors and also provide a detailed review of 12 archiving solutions. This was followed by presentations from 4 different providers of archiving and preservation services. Victoria Reich (PDF 13MB) , Director of the LOCKSS program, gave an overview of LOCKSS and CLOCKSS and emphasised that the more archived copies of an item the safer it is. Eileen Fenton (PDF 593KB), Executive Director of Portico, described the service provided by Portico which archives peer review scholarly journals and to date has more than 5,800 journals from 30 publishers. Erik Oltmans (PDF 377KB), Head of Acquisitions and Cataloguing at the National Library of Netherlands (Koninklijke Bibliotheek) spoke of the e-deport service which from a starting point in 1995 is now ingesting 50,000 items a day. The UK national library perspective was given by Richard Boulderstone (PDF 418KB), Director of e-Strategy at The British Library, who showed that the traditional scholarly communication process is changing and this requires new processes and durable technical architecture to ensure that archiving solutions are able to satisfy requirements now and in the future.

The afternoon session saw presentations from the publisher and university library perspectives. Steven Hall (PDF 156KB), Commerical Director at Wiley-Blackwell, demonstrated that publishers take the issue of archiving seriously but there needs to be more clarification when it comes to access. Preservation is not the same as access and access is not the same as open access. Paul Ayris (PDF 440KB), Director of Library Services at UCL, said that UCL were moving towards the e-only delivery of journals and therefore were reviewing what solutions need to be in place to ensure continued access. Paul also highlighted the potential costs of archiving.

The workshop finished with a question and answer session which enabled delegates to pose questions to the expert panel and Hazel Woodward brought the day to an end by summarising the themes of the day.
