The Digital Divide: Assessing Organizations' Preparations for Digital Preservation

Posted in Digital Curation & Digital Preservation on May 13th, 2010

Plants has released The Digital Divide: Assessing Organizations' Preparations for Digital Preservation.

Here's an excerpt:

  • The volume of digital content that organizations expect to archive will increase 25-fold over the next ten years.
  • While seventy per cent of organizations hold less than 20 terabytes (TB) of data now, by 2019 seventy per cent of organizations expect to hold over 100TB.
  • Digital information comes in a range of types, and while over 80% of organizations already need to preserve documents and images, by 2019 over 70% will need to preserve databases, websites, audio and video files as well.
  • Only 27% of organizations think that they have complete control over the file formats that they will accept and store in their digital archives. Since the choice of format affects how easy it is to preserve digital content, producers need to be more involved in digital preservation.
  • The digital preservation message has spread far and wide: 93% of respondents indicated that their organisation is aware of the challenges of managing digital information for the long-term.
  • Organizations are taking account of digital preservation: 76% include it in their operational planning, 71% in their business continuity planning and 62% in their financial planning.
  • By setting out a digital preservation policy, 48% of organizations are actively planning how to tackle digital preservation.
  • Organizations are only starting to commit to funding digital preservation, as just 47% have allocated a budget to it.

    Digital Curation and Preservation Policies in Scottish HEIs: Survey Results

    Posted in Digital Curation & Digital Preservation, Digital Repositories, Institutional Repositories on May 10th, 2010

    The Digital Curation Centre has released Digital Curation and Preservation Policies in Scottish HEIs: Survey Results.

    Here's an excerpt:

    The survey showed that repositories are still relatively young, and that preservation is not yet the highest priority for them. The situation with preservation policies also reflects the early stage of repository development, where the need to apply explicit curation policies is only beginning to be acknowledged.

    The survey did not identify any institution level preservation policies, but given the heterogeneity of digital information across any higher education institution, it is not surprising that institution-wide preservation policies have yet to be formulated. Repository level policies were found to be in place at four institutions that also reported to be offering preservation services.

    The survey reported a very low level of awareness of both existing preservation policies and digital preservation issues in general, especially amongst administrative and research staff. Enforcing preservation policies and making them effective are challenges that all HEIs face; at the same time, this formative period could be considered an opportunity for the ERIS project to develop supporting tools and guidance, especially since the prospect of additional guidance and the possibility of centralised services for preservation were welcomed by the respondents.

        Posted in Data Curation, Open Data, and Research Data Management, Digital Curation & Digital Preservation on May 6th, 2010

        Alex Ball has deposited Review of the State of the Art of the Digital Curation of Research Data in Opus.

        Here's an excerpt :

        The aim of this report is to present the state of the art of the digital curation of research data, in terms of both theoretical understanding and practical application, and note points of particular interest to the ERIM Project. The report begins by reviewing the concepts of data curation and digital curation, and then exploring the terminologies currently in use for describing digital repositories and data lifecycles. Some parallels are also drawn between digital curation practice and design and engineering practice. Existing guidance on data curation from research funders, established data centres and the Digital Curation Centre is summarized in section 3. A review of some important standards and tools that have been developed to assist in research data management and digital repository management is presented in section 4. Finally, a short case study of implementing a new data management plan is presented in section 5, followed by some conclusions and recommendations in section 6.

            Library of Congress to Archive All Public Tweets Since March 2006

            Posted in Digital Curation & Digital Preservation, Research Libraries, Social Media/Web 2.0 on April 14th, 2010

            The Library of Congress has tweeted that it will to archive all public tweets made since March 2006.

            Here's an excerpt from the blog announcement:

            Have you ever sent out a "tweet" on the popular Twitter social media service? Congratulations: Your 140 characters or less will now be housed in the Library of Congress.

            That’s right. Every public tweet, ever, since Twitter’s inception in March 2006, will be archived digitally at the Library of Congress. That’s a LOT of tweets, by the way: Twitter processes more than 50 million tweets every day, with the total numbering in the billions.

            We thought it fitting to give the initial heads-up to the Twitter community itself via our own feed @librarycongress. (By the way, out of sheer coincidence, the announcement comes on the same day our own number of feed—followers has surpassed 50,000. I love serendipity!)

            We will also be putting out a press release later with even more details and quotes. Expect to see an emphasis on the scholarly and research implications of the acquisition. I'm no Ph.D., but it boggles my mind to think what we might be able to learn about ourselves and the world around us from this wealth of data. And I'm certain we'll learn things that none of us now can even possibly conceive.

              "Data Curation and Libraries: Short-Term Developments, Long-Term Prospects"

              Posted in Digital Curation & Digital Preservation on April 12th, 2010

              Anna Gold has self-archived "Data Curation and Libraries: Short-Term Developments, Long-Term Prospects" in DigitalCommons@CalPoly.

              Here's an excerpt:

              This paper was prepared as background for a talk given at AGU 2009 on "Data & Libraries." It summarizes the developments and events from late 2006 through early 2010 that are shaping library roles in scientific data curation while underscoring the range, complexity, and varying granularity of systems, actions, and efforts involved. The main conclusions are: (1) leaders of major research libraries have committed their institutions to support data curation. (2) The library profession has demonstrated significant conceptual progress in characterizing and understanding data curation both in theory and in practice. (3) There has been progress since 2006 in legitimizing library roles in data curation through formal education and certification programs as well as by integrating data curation into established library services and systems. Certain questions remain unresolved: how will data taxonomies or ontology, schemas or data models and their databases fit into data curation practices? Librarians, however, can draw on a growing body of experience and the support of a community of practice as they contribute to data curation, while researchers and those who fund research can turn with growing confidence to libraries and librarians for data curation support.

                    Ensuring Perpetual Access: Establishing a Federated Strategy on Perpetual Access and Hosting of Electronic Resources for Germany

                    Posted in Digital Curation & Digital Preservation on March 30th, 2010

                    Charles Beagrie Ltd has released Ensuring Perpetual Access: Establishing a Federated Strategy on Perpetual Access and Hosting of Electronic Resources for Germany.

                    Here's an excerpt:

                    This study was conducted as basis for all further steps towards a national hosting strategy. It was financed jointly by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation), the Fraunhofer-Gesellschaft, the Helmholtz Association, the Leibniz Association and the Max Planck Society. The study is intended to be the starting point from which to arrive at concrete ideas and activities related to a coordinated national hosting strategy. The intensive, often controversial but always constructive and continuing discussion now expands out of the working group into the public area to be continued there in the same manner. Invited for further discussion are all stakeholders with responsibility in the German science system to establish and finance sustainable structures for perpetual access as well as long-term preservation for electronic resources.

                        Here's an excerpt from the announcement:

                        The DCC has produced a report that provides a snapshot of the state of the art of Web archiving in early 2010, noting areas of contemporaneous research and development. It should be of interest to individuals and organisations concerned about the longevity of the Web resources to which they contribute or refer, and who wish to consider the issues and options in a broad context. The report begins by reviewing in more detail the motivations that lie behind Web archiving, both from an organisational and a research perspective. The most common challenges faced by Web archivists are discussed in section 3. The following two sections examine Web archiving at extremes of scale, with section 4 dealing with full-domain harvesting and the building of large-scale collections, and section 5 dealing with the ad hoc archiving of individual resources and small-scale collections. The challenges associated with particular types of difficult content are summarised in section 6, while methods for integrating archived material with the live Web are reviewed in section 7. Finally, some conclusions are drawn in section 8.
