Digital Preservation Matters - 30 November 2007

Council Conclusions on scientific information in the digital age: access, dissemination and preservation. The Council Of The European Union. November 2007.

The Council of the European Union presents some conclusions regarding digital preservation and recommendations during the next few years:

• access to and dissemination of scientific information is crucial and can help accelerate innovation;
• effective digital preservation of scientific information is fundamental for current and future development of research
• it is important to ensure the long term preservation of scientific information, publications and data, and include scientific information in preservation strategies;
• monitor good practices for open access to scientific information and development new models
• experiment with open access to scientific data and publications to understand contractual needs
• encourage research and experiments into digital preservation on deploying scientific data as widely as possible for open access to and preservation of scientific information.

Shifting Gears: Gearing Up to Get Into the Flow. Ricky Erwayr. OCLC. October 2007.

Efforts to digital special collections mean we need to re-look at what we are doing. Do we digitize for access or preservation, or both. How do our selection criteria affect the digitizing efforts. Access is important. We should preserve the unique items to the best of our ability, but it doesn’t mean we only have once chance to do it right. We may want to re-digitize when the technology improves. Scan items as part of the initial accessioning process; create a single unified process. Metadata can be improved as needed; it can be an iterative approach. Move to a program approach, not just special projects. It should be part of the regular budget. To do a better job we need to “integrate digitization into all workflows and user services”.

Digital library surpasses initial goal of 1 million books. International Herald Tribune. November 27, 2007.

The Universal Library project has surpassed its latest target, having scanned more than 1.5 million books. At least half the books are out of copyright or scanned with the permission of copyright holders. The library's mission is to make information freely available and to preserve rare and decaying texts. It is the largest university-based digital library of free books and its purpose is noncommercial. The library has books published in 20 languages, including 970,000 in Chinese, 360,000 in English, 50,000 in the southern Indian language of Telugu and 40,000 in Arabic.

Presentations from iPRES - 2007 International Conference on Preservation of Digital Objects. National Science Library . November 2007.

Towards the Australian Data Commons: A proposal for an Australian National Data Service. The ANDS Technical Working Group. October 2007.

This paper, among other topics, discusses the reasons to focus on data management, the issues, and the programs to deliver the data. While the paper looks specifically at a national data service, there are aspects that are useful for local digital preservation. Here are some interesting notes from it.

• Important activities include identifying and deploying policies and technologies to allow users to gain seamless access to data collected within multiple institutionally operated repositories.
• The intent is to provide common services to support research to make it easier to discover, access, use, analyze, and combine digital resources as part of their activities. They should also support and advise researchers and research data managers about appropriate digital preservation strategies.
• We are in a data deluge. It can only continue and grow in intensity as the number, frequency and resolution of data sources rises and as information becomes universally ‘born digital’.
• Data is an increasingly important and expensive ingredient of research activities and needs increasing attention to be managed efficiently and effectively.
• The sponsors of data capture and care should help determine the accessibility of the data
• Not everyone can use the same solution, so there may need to be multiple responses.
• There should be a registry of repositories with services offered
• Provide assistance to others on adopting the plans and getting the service they need.
• Collecting and managing the metadata is critical. Best to collect early and automatically.

The data service believes it can contribute most effectively by developing services and activities that enable stewardship within multiple federations of data management and data user communities.

In ten years time, it will be successful if:

• A data commons exists in a network of research repositories and the data is discoverable;
• Researchers and data managers perform well with well formed data management policies;
• More research data is routinely deposited into stable, accessible and sustainable environments;
• More people have relevant expertise in data management

Stewardship of digital resources involves both preservation and curation. Preservation entails standards-based, active management practices that guide data throughout the research life cycle, as well as ensure the long-term usability of these digital resources. Curation involves ways of organizing, displaying, and repurposing preserved data.

Digital Preservation Matters - 16 November 2007

Electronic Records Management and Digital Preservation: Protecting the Knowledge Assets of the State Government Enterprise. Eric Sweden. NASCIO. October 2007. [pdf]

Electronic records management and digital preservation must be a shared responsibility, including understanding and support, from the CIO. Everyone needs to be part of managing digital assets. These initiatives must be managed on the organizational level. The team needs enterprise architects, project managers, electronic records managers, librarians and archivists to ensure the knowledge assets are managed properly. Technology create both opportunities and challenges. The goal of Digital Preservation systems is to make sure the information they contain remains accessible to users over a long period of time. A challenge is to keep bit streams intact and usable long term. You need to know what to preserve and how to preserve the records. The strategy must address preservation for the life of the record. There is not a single best way to preserve digital materials. Digital materials do not allow preservation procrastination. If a record needs to be maintained for over 10 years, the original technology will probably be obsolete. Digital Preservation must be a routine operation, not a special event.

RSA 2007: long-term data storage presents legal risks. Ian Grant. Computer Weekly. 23 Oct 2007.

Art Coviello, executive vice-president of EMC, stated at a conference that storing every piece of data long term may place organizations at risk of legal liability. The organization needs to know what data they have, who is looking at it and what they are doing with it. They should classify data and users before they store data. This is needed to protect the data and to reduce information clutter.

Keep 'Smoking Gun' E-Mails From Backfiring. H. Christopher Boehning, Daniel J. Toal. New York Law Journal. October 25, 2007

While this is written from a legal and not archival perspective, the article discusses the importance of validating / authenticating electronic documents. It lists the legal rules for authenticating emails and other electronic documents, including:

• testimony by a witness with knowledge of the object;
• circumstantial means ("appearance, contents, substance, internal patterns or other distinctive characteristics, taken in conjunction with circumstances," such as the email address;
• hash values that serve as a digital fingerprint; comparison to existing documents;
• self authentication of items with labels, tags, or ownership marks.

The Aftermath: Examining the E-Discovery Landscape After the 2006 Rule Changes. Eric Sinrod. FindLaw. October 16, 2007.

Another article emphasizing the importance of records management plans for electronic data. It mentions that “Data can be located live on networks, servers, hard drives, laptops, PDAs and on backup tapes.” Purging according to retention policies is important. Data may be required in ‘native’ format with all metadata intact.

‘Digital curators’ lead cultural IT projects. Shane Schick. ComputerWorld Canada. 8 Nov 2007.

As cultural organizations try to reach new audiences online and integrate their collections into multimedia-friendly exhibits, they are starting to face the same challenges as others who have been moving away from paper-based processes. These challenges include not only figuring how to digitize content but what gets preserved first, what can wait and what doesn’t need to be digitized at all. Institutions face the difficulty of trying to preserve something indefinitely, without knowing how formats might change over time. They must collecting the right hardware and software along with the content itself. “Archives are now building in budgets for migration strategies for data.”

HD Photo to become JPEG XR. Stephen Shankland. CNet News. November 2, 2007.

The Joint Photographic Experts Group has approved Microsoft's HD Photo format as a standard called JPEG XR. This is an important step to make the format neutral. It is designed for the next generation of digital cameras and was based on Microsoft’s Windows Media Format. Microsoft is committed to make the patents available without charge. The standardization process typically takes about a year. (See also http://www.jpeg.org/newsrel19.html).

PRONOM and DROID - new versions released. Neil Beagrie. National Archives UK. November 2, 2007.

The National Archives in the UK has released new versions of PRONOM and DROID. PRONOM is an online registry of file formats, software, and other technical information used for digital preservation purposes, available at http://www.nationalarchives.gov.uk/pronom. DROID (Digital Record Object Identification) is open source software at http://droid.sourceforge.net/ that is used to identify file formats in batch mode. They are freely available.

LOCKSS: Does a Library Good? An Investigation into the Implementation of LOCKSS. Caitlin Hoffman. Blog. November 8, 2007.

An overview of LOCKSS, how it works, and issues related to it. (LOCKSS, developed at Stanford University, stands for Lots of Copies Keeps Stuff Safe.) One of the main issues surrounding it is the issue of trust. “Trusting a single provider, a single institution, and a single archive represents the real risk”. LOCKSS is built on the principle of building confidence in the archive. LOCKSS was built to archive electronic journals but has been enhanced to also archive blogs on Google’s Blogger.

Looking Ahead. Lee J. Nelson. Advanced Imaging Magazine. November 9, 2007.

The article looks at some of the industry trends. Included is an announcement on an HD Photo Plug-in for Adobe Photoshop. “HD Photo is geared for end-to-end digital photography, offering better image quality, greater preservation of data and advanced features. Its still image codec for continuous-tone images is underpinned by lossy and lossless compression, multiple colorspaces, wide dynamic range and extensive metadata.”

Government Pledges £25m To Preserve Uk's Film Archives. 24 Hour Museum. October 17, 2007.

The British government has taken steps to preserve the country’s film archives. They have given money to the UK Film Council to secure the films in the archives. “It’s absolutely right that they should be safe and accessible for future generations.” The £25million plus £3million are to be used to preserve, restore and increase access to the collections, some of which are deteriorating and in danger of being lost.

Library of Congress Collaborates with Xerox To Test Format for Digitally Preserving, Accessing Treasured Images. News Release. Library of Congress. October 25, 2007.

The Library and Xerox are studying the potential of using the JPEG 2000 format in large repositories of digital materials. The project is designed to help develop guidelines and best practices for digital content. The trial will include up to 1 million tiff images to be converted to JPEG 2000. Xerox will build and test the system, and they look specifically to create profiles for the objects. Xerox already created a profile for using the JPEG 2000 format for newspapers.

Digital Imaging - How Far Have We Come and What Still Needs to be Done? Steven Puglia, Erin Rhodes. RLG DigiNews. April 15, 2007.

This is an overview of digital imaging over the past 10 years. It has moved beyond the experimental stage, though in many institutions is still isn’t a mainstream program. There is a growing understanding of the significant investment required for digital initiatives, particularly in the infrastructure, standards, metadata, and managing them long term. The more we learn, the more there is to learn. Some feel we are carrying the flawed earlier ‘preservation reformatting’ such as microfilm into the digital areas. Technology is never “THE answer” to our problems. The goal is to use the tools wisely, not just to have the technology. Often digital preservation was an extension of microfilming brittle books. But users are asking more than what microfilm could provide. We are still asking many of the same questions we were asking 10 years ago. We have accepted digitization, but it is not “completely synonymous with preservation”, though we are moving forward. Every project may have different digitization and preservation needs.

A Digital Decade: Where Have We Been and Where Are We Going in Digital Preservation? Nancy McGovern. RLG DigiNews. April 15, 2007. [new link]

There has been progress in digital preservation since the first recommendations were published in 1996. Some elements include: OAIS; Trusted Digital Repositories; a preservation metadata data dictionary; or the options of digital repositories. There is a conference devoted just for digital preservation (iPres) and more literature on the topic. There is an increase in the number of standards now. The three components of a digital preservation approach presented at the Cornell workshop are organizational, technological, and resources. The organizational is the “what”, the technological is the “how” and the resources is the “how much” is needed to produce the outcomes. A challenge is to balance time and resources of developing a repository internally against the external environment. ‘There is currently no “one stop shopping” for keeping up with digital preservation research and development. Keeping up takes effort, but it is worthwhile.’

Copyright Keeps Open Archives and Digital Preservation Separate. Peter B. Hirtle. RLG DigiNews. April 15, 2007.

Open access and self-archiving repositories enhance access to current research but do not necessarily provide long term preservation of the contents. Libraries cannot rely on those repositories for at least two reasons.

• The repositories lack the technical, organization and financial support needed to preserve materials.
• The deposit agreements do not necessarily convey the preservation rights needed. 

“Digital preservation, by its very nature, must impinge upon the rights of the copyright owner” since they need to be copied and recopied. Copyright law does not does not give a general exemption for preservation. Typical deposit agreements do not include the preservation rights. Deposits without the right to preserve may put the repository at risk, though it is difficult to say how much. Only the “journals that are part of formal third party journal archiving programs can be said to be effectively preserved. In sum, libraries cannot yet rely upon open archives for long-term access to the journal literature.”

Road Report: Second Annual Open Repositories Conference (OR07) in San Antonio. Carol Minton Morris. D-Lib Magazine. March 2007.

The conference presented sessions on DSpace, Fedora, and Eprints, including user groups for each software. Open source software may be free, but does not mean “no cost”, it brings maintenance costs. Choose the right partners to create a competitive advantage instead of competing with your associates. Fedora allows for complex digital objects. The new Fedora Commons will provide a non-profit organization to support the growing community. The next conference will be held April 1-4, 2008.

Conference addresses archiving and preservation of e-journals. Phillip Pothen. JISC. 28 March 2007.

The uncertainty of long-term access to scholarly journals is a major issue for libraries and others. A recent conference discussed the topic and said that major concerns still remain even though progress has been made. A great deal of content is still at risk. Librarians should press the archiving programs to make sure they meet their archiving needs. Librarians are the custodians of the content. The group of libraries saving the data can do more than individuals alone. LOCKSS and Portico are some methods in use. The e-Depot in The Netherlands is also archiving journals from some publishers. “Old business models are breaking down while long-term archives require highly resilient architectures, long-term funding and a commitment to quality.” Blackwell suggests that 50% of all serials publications will be online by 2016, while 39% of science journals will be online by the end of this year. This means that there are considerable preservation challenges. Preservation, access, and open access are not the same thing. “Digital curation needs to be embedded in institutional strategies.” Responsibilities and requirements must be clear and agreed upon.

History 1980-2000 has disappeared into the ether. Sorry. Ben Macintyre. The Times. March 23, 2007.

This commentary warns of the short life of digital objects, which are “dangerously disposable.” Many do not bother to archive their digital data. Historians may look back at this period as a black hole. The most important real-time histories are written in online forums, which are fleeting. Many items have already been lost. The article ends with a plea for paper, which he feels is the best way to save things.

Tools and Methods for the Digital Historian. AHRC. March 23, 2007.

The Arts & Humanities Research Council (AHRC) has created an online forum, ‘Tools and Methods for the Digital Historian’ in order to encourage the exchange of ideas. The Methods Network is a UK initiative which provides a place for discussing digital history and research, but it open to all who want to register and discuss the issues. It also refers to a set of Working Papers.

FastStone Image Viewer 3.1. FastStone Website. April 16, 2007.

JPEG 2000 - Do you use it? John Nack. Adobe blog. April 02, 2007.

Photoshop has contained a plug-in for reading and writing jpeg2000 files. However, Adobe has not seen the widespread adoption of the format. With Photoshop CS2, they decided to stop installing the plug-in by default, though it is still currently available. If features no longer make sense, they will retire them in order to focus on what is most important. Adobe is trying to gauge the value of standalone jpeg2000 reading and writing. [Lots of comments on the blog.]

Questioning the Future of JPEG2000 Support in Photoshop. Peter Murray. TLDJ. April 5, 2007.

There is still some uncertainty about the format and whether it will be used much. The response to the Abode survey has been disappointing that not many use jpeg2000. It would be a shame if support were dropped since the format seems to be gaining ground. Google lists projects where some are working on wider adoption of the format.

Metadata mangling in Windows Vista. Stephen Shankland. CNet News. February 8, 2007.

Windows Vista and the Photo Info tool can cause problems with some images or the metadata. Some cameras use an EXIF Maker Note Tag in the image, and when updated, the digital camera software “may no longer recognize the metadata that is automatically added to the photo." There have also been reports of some compatibility issues and the files becoming “unreadable in other applications, such as Adobe Photoshop." Camera manufacturers may provide software for Vista users who want to open or print raw files.

Intel Gets More Time to Explain Lost E-Mails in Antitrust Case. Chris Preimesberger. eWeek. April 6, 2007

Intel has been granted more time by the court to explain how they will locate missing emails. Guidelines enacted in December require enterprises to be able to quickly find data files required by the court. Some of the items may have to be recovered from backup tapes or user backups, neither of these are indexed. The court said they had an “ill-conceived plan of document retention and lackluster oversight”. People at the highest level “failed to receive or to heed instructions essential for the preservation of their records”.

Testimony to Congress. James H. Billington. Library of Congress. March 20, 2007.

Statement given by the Librarian of Congress concerning the Library of the 21st Century. It now takes 15 minutes to produce the same amount of information that it took LC over 200 years to acquire. Most exists only in digital form. “There is a widely-held but false assumption that digital materials accessible today … will necessarily be available in the future.” Also, “information not actively preserved today could literally be gone tomorrow.” Recent important digital materials, such as those on the internet, have not been preserved and have vanished. These are the primary sources of our time. A key challenge is to “capture, collect, preserve, and provide access to important ‘born-digital’ material and Web-based information.” LC manages about 295 TB of digital information. “The Library's basic mission of acquiring, preserving and making accessible the world's knowledge and the nation's creativity is not changing.” We can’t save everything, so we need to identify and select what is critical to the collection. “We are not just creating endless digital data files; we are giving our collections context and making them increasingly accessible to the world.” As we add to our collections we need an infrastructure that will make the content available in the future. A new asset is LC’s National Audiovisual Conservation Center which will preserve and make accessible the audio – visual collections.

Killing risk, unifying data protection. Jim Damoulakis. Computerworld. February 27, 2007.

It is important to look at what we are doing with data protection. Some of the techniques include nightly backup, snapshot, mirroring, database dumps, host-based replication, and storage array-based replication. One way to create a unified strategy is to look at the risks that exist. They include physical device failure, data loss through deletion or corruption, and disasters. Data loss can occur undetected, and there needs to be a way to protect against this.

Perspectives on Trustworthy Information. H.M. Gladney. Digital Document Quarterly. March 2007.

Digital preservation activities are shifting from solving basic problems to implementing solutions and repository procedures. Selection is a challenge of building a long-term digital collection, but it need to be balanced by practicalities. Archival objects need to include honest and adequate provenance information that is bound to the object. “Preserving an information collection is a different challenge than managing archives.” The need to preserve digital information, which is the base of most scientific research, is self-evident. Snapshots and logs may be sufficient for preserving databases.

JHU/UVA Medieval Manuscript Digitization Workshop. Timothy Stinson. Blog. March 28th, 2007.

This quote is from the blog report of the digitization workshop: “Staples has a great way of thinking about preservation - he pointed out that preservation isn’t simply a technological solution, an archive, e.g., where we can stick things and have them safe forever. Rather preservation is the result of usage, maintenance, and institutional commitment. Those things that are used the most, he argued, are the same ones that are migrated the most frequently, and are the least likely to become invisible and forgotten or to cease to be a priority to individuals and institutions. We need not only technical solutions, but also wide access and modeling of data in such a way that it is frequently used, migrated, and repurposed.”

Calif. CIO Steers Clear of Ideology on File Formats. Carol Sliwa. Computerworld. March 19, 2007.

The question of open formats is not an ideological struggle between competing visions of the future. It is a straight business decision, looking at the costs of one approach over another and deciding if it meets the business needs. They don’t have a preference between ODF and Office Open XML file format, but they are moving to interoperability and things that are more open and stop being locked in to proprietary systems. Open, XML-based formats provide flexibility.

Trustworthy Repositories Audit & Certification (TRAC): Criteria and Checklist. Robin Dale, et al. CRL. March 9, 2007.

TRAC is the revised and expanded version of the Audit Checklist originally developed by RLG-NARA. The 94 page report provides a very complete method for checking and certifying long-term repositories. It can also be used for planning and guiding the development of repositories. The document looks at Organizational Infrastructure, Digital Object Management, and Technologies, Technical Infrastructure, & Security, and provides a checklist of criteria for measuring the trustworthiness of repositories. Another link to the site.

e-Journals: Archiving and Preservation. Briefing Paper. JISC. March 2007.

The traditional model of publishers supplying content and libraries preserving content does not work well with digital materials. Licensing agreements do not guarantee permanent access to materials. But the e-journal trend is increasing at a rapid rate. Many are searching for the solution. The terms ‘perpetual access’, ‘archiving’, and ‘long-term preservation’ are often used interchangeably. Perpetual access is usually used with e-journal licenses clauses to assure that access will be continued regardless of events. Archiving describes the management processes of e-journals. Long-term preservation refers to the processes to ensure the content remains accessible in the future, regardless of any technical or organizational changes. There needs to be multiple options and strategies for preserving e-journals, including coordinated overlap. There are promising developments evolving, but the solutions must include libraries, publishers, and archiving services.

Iron Mountain launches active archiving for email. Computer Technology Review. March 20, 2007.

Iron Mountain has introduced an Active Archiving Service for email. This is a single solution which includes management, archiving, legal discovery, continuity and disaster recovery. Most legal discovery processes now include email. The new federal rules make an email archive critical. It is integrated with Outlook and allows users full access to emails and the ability to restore individual messages. The cost starts at $6 per user per month.

Metadata for All: Descriptive Standards and Metadata Sharing across Libraries, Archives and Museums. Mary W. Elings, Günter Waibel. First Monday. 5 March 2007.

The cultural heritage community has a large pool of digital resources for teaching, research and learning. A big challenge is integrating digital content from libraries, archives and museums which use different strategies for caring for their materials. Applying data content standards by material type rather than the organization could make the data more usable within the entire community. Two schema used are Visual Resources Association (VRA) Core and the Categories for the Descriptions of Works of Art (CDWA). The article lists the elements of metadata standards, and the relationship between them and museums, libraries and archives. There is a call among archives to process collections more efficiently so they achieve control over all their holdings. The successful use of digital materials in libraries, museums, and archives revolves around the ability to describe similar materials in different institutions.

Microsoft Announces HD Photo, a New Imaging File Format With Advanced Features for Today’s Digital Photographers. Press release. March 8, 2007.

Microsoft announced a new file format for that offers higher image quality, greater preservation of data, and advanced features. HD offers both lossless and lossy image compression. When compressed it has twice the efficiency of JPEG, with fewer artifacts. It preserves the entire original image. They also released a plug-in for Photoshop. [See Photoshop gets HD Photo support.]

A Digital Life. Gordon Bell, Jim Gemmell. Scientific American. February 18, 2007.

New systems may allow people to record everything they see and hear--and even things they cannot sense--and to store all these data in a personal digital archive. The MyLifeBits project has provided the tools to create a person’s lifelong digital archive. Technological advances may make this easier but there are challenges, particularly with privacy rights and restrictions. They believe digital memories will yield benefits in many areas.

History, Digitized (and Abridged). Katie Hafner. New York Times. March 10, 2007

Archives and museums hold many important items that will probably not be digitized in the near future. This increases the possibility that they will be ignored as people expect more that all information is on the internet. A major problem is the cost of digitizing materials. Many items will still exist only in paper, LPs, magnetic tape and film. Libraries tend to digitize the items that are unique to their collection. But by putting the items on the internet, the number who use them increase dramatically. The LDS Church has initiated large scanning projects and hopes to have hundreds of millions of images online in the next five years. Others are digitizing collections which allow much broader access to the materials, but copyright is an issue. There is very little room in copyright law for preservation. The amount of material available can be overwhelming.

Director's Message. Anne-Imelda M. Radice. News & Events. March 2007.

The Webwise Conference: Stewardship in the Digital Age: Managing Museum and Library Collections for Preservation and Use highlighted the huge shift underway in museums and libraries. In a short time they have gone from knowing almost nothing about preserving digital objects to now understanding that digitization is an important part of conservation and use. Besides preserving the physical objects, institutions realize they need digital repositories for collections that are:

- physically vulnerable

- on fragile or unstable media

- born digital

Digitization protects historically important collections and addresses future collections. There is a great need to develop a new set of digital preservation skills in order to address digital objects. These collections can increase public awareness and interest in existing collections that may currently be unknown. Digital stewardship is an important part of the overall mission of libraries and museums as they care for their collections.

Quad-layer DVD Technology Becomes the Third HD Format. Marcus Yam. DailyTech. March 11, 2007.

New Medium Enterprises (NME) has developed the Versatile Multilayer Disc (VMD), a new optical-based format capable of storing 20GB of data. VMD is a red-laser technology that achieves its storage capacity by using a greater number of layers. VMD is the same size and thickness as DVD. However, while DVD technology uses two layers of a disc, VMD technology has multi-layering where up to 5GB can be stored on each layer.

Intel Faces Up to E-Mail Retention Problems in AMD Lawsuit. Chris Preimesberger. eWeek. March 7, 2007.

A U.S. federal judge on March 7 gave Intel 30 days to try to recover about 1,000 lost e-mails that it was required to keep for an antitrust lawsuit. The suit was filed AMD (a competitor) in 2005. Intel could have been easily avoided the digital storage problems with careful planning. The new U.S. federal court rules enacted last December require companies to be able to quickly find data required by the federal court.

Principles for Digitized Content. ALA. Website. March 2, 2007.

An ALA task force introduced the draft Principles for Digitized Content. These have been put on the ALA blog and they are interested in comments. The principles in brief are:

1. Digital libraries ARE libraries and ALA policies and values apply fully.

Digital Repository Audit Method Based on Risk Assessment. Website. March 1, 2007.

The Digital Curation Centre and DigitalPreservationEurope have released the Digital Repository Audit Method Based on Risk Assessment (DRAMBORA) toolkit. This is to provide repository administrators with a way to audit and assess the capabilities, weaknesses, and strengths of their repository. This model is designed to respond to developments; it follows the DCC audit process for various types of archives. This 221 page document is very comprehensive and expects that the organizations, processes, and documents are already in place. Registration is required to download the document and worksheets.

Review and analysis of the CLIR e-Journal Archiving survey. Maggie Jones. JISC. 7 March 2007.

A review of e-journal archiving is now available. This site has a link to the report “E-Journal Archiving: Review and Analysis of the CLIR Report E-Journal Archiving Metes and Bounds: A Survey of the Landscape, by Maggie Jones”, as well as an executive summary. The trend to e-journals is increasing. LOCKSS and Portico have provided a momentum in this area. The report lists the basic principles for this effort, mostly for the services and nationally. Of special interest are:

• There must be an explicit commitment to digitally archive scholarly peer-reviewed journals.
• Form a network to exchange information with others on what you are doing.
• Participate in at least one long term initiative.
• Act collectively to address long-term accessibility
• Participate in a registry of archived scholarly publications
• Have a preservation mandate
• Initiate either formal or informal certification and articulate practices and procedures
• Create publicly accessible policies and procedural documents.
• Clearly state access conditions
• View the preservation of electronic journals as a necessary investment.
• Support a range of options and solutions and collaborate

Manage risks appropriately. Having the publisher responsible for archiving is a high risk strategy. A single definitive approach to e-journal archiving is unlikely ever to emerge. The article provides an in-depth look at LOCKSS, CLOCKSS, Portico, PubMed Central, and others.

Electronic Resources Management and Long Term Preservation: (Is the library a growing organism?) Tommaso Giordano. E-LIS. 02 March 2007.

Digital preservation is a complex issue that involves many areas of expertise. This paper looks at how academic libraries see preserving e-journals and the organizational practices. License controls may control access to the current year, back issues, and an archival copy. Perpetual access and archiving right are different. Getting an archive copy is only the first step, there is more to implementing long-term access. Digital preservation may not be possible for every library. Digital preservation is a costly operation which considerable and long-term commitments, beyond current budgets. This is a high-level strategic issue. There is a shift from the traditional model to one based on renting resources with no guarantees for the future. Sustainability is a question.

The End of Online Storage: Coming Soon. Brian Bergstein. MCPmag. March 5, 2007.

A new study estimates that the amount of digital information the world is generating has increased dramatically. The study tries to account for photos, videos, e-mails, web pages, instant messages, phone calls and other digital content. They estimate that 40 exabytes of original data was created last year, and that it would be 161 exabtyes if you count the times it is duplicated. They wonder if enough is being done to save the digital data for posterity. "Someone has to make a decision about what to store and what not. How do we preserve our heritage? Who's responsible for keeping all of this stuff around so our kids can look at it, so historians can look at it? It's not clear."

Google helps terabyte data swaps. Darren Waters. BBC News. 7 March 2007.

Google is developing a program to physically transfer large data sets around the internet. Some data sets may be 120 terabytes in size. Google is collecting the data sets and sending them to scientists who want them. This was started after researchers working with The Archimedes Palimpsest had problems transferring the enormous data sets from place to place. “Google keeps a copy and the data is always in an open format, or in the public domain or perhaps covered by a creative commons license.” They hope some day the data can be open to the public.

Pre-Pixel Preservation: Concept Device to Archive and Preserve the Past. Naveen Shimla. Gizmo Watch. February 27, 2007.

Library Copyright Alliance Strongly Supports H.R. 1201, the FAIR USE Act. Jonathan Band. District Dispatch. February 28, 2007.

The FAIR USE Act would make a film clip exemption applicable to all classrooms not just college media studies classes. It would also allow a library to legally circumvent technological protections in order to preserve encoded works in a library's collection. Preservation is one of the most critical library functions. The DMCA provides obstacles to a library’s ability to preserve some objects; the FAIR USE Act will remove the obstacle without harming copyrights.

Hard Disk MTBF: Flap or Farce? David Morgenstern. eWeek. February 28, 2007.

Computer hard drive reliability is rated in hours: known as MTBF (mean time between failures). Some drives are rated at 1.5 million hours, which is over 100 years. Now some are questioning this statistic. They have found that replacement rates are sometimes as high as 13%, and there is little difference between SCSI, FC, and SATA drives. In reality, there isn't a reliable way to statistically determine the reliability of disk drives that are in use. Expecting that data won’t get lost is not realistic, even with a Raid array. Budgets must include regular hard drive replacement.

Back stage at the Oscars with Martin Scorsese: The press interview. Movie News. February 27, 2007.

This interview contains a brief discussion with Martin Scorsese about film archiving and preservation. He is a proponent of film preservation and film archiving. “It's very important. We don't know what new technology is coming down the line. Digital also fades. We have to be very careful.” There is so much to be done, but choices have to be made. They are trying to restore older films on celluloid, but it is expensive and only a very few can be done. If the only thing you can do is transfer them to digital to preserve them, then that may have to be done. With small budgets, preservation is a serious problem.

Adobe to take Photoshop online. Martin LaMonica, Mike Ricciuti. CNET News. February 28, 2007

Adobe plans to release an online version of Photoshop within six months. The lower-end version is expected to be free and will be an entry-level version of the full products. Adobe is trying to find how to use web services for their products. Other vendors have already started doing similar things. Google’s free Picasa program allows users to manage images and to read Adobe Photoshop files.

California may join rush of states toward ODF. Eric Lai. Computerworld. February 27, 2007.

A bill in the California legislature would mandate open, XML-based document file formats in the state government starting next January. Several other states are also considering this. This initiative seems to support the Open Document Format used in OpenOffice.

Google Study Examines Effects on PC Hard Drives. Mark Hachman. ExtremeTech. February 20, 2007.

Disk drives are generally reliable, but a study shows that current methods of predicting hard drive failure are almost ineffective, while basic disk checks can show if a drive is about to fail. The study looked at over 100,000 drives from different manufacturers over a 5 year period. There was no clear pattern to show that higher temperatures, higher utilization or activity levels affected the failure rate. Lower temperatures and very high temperatures had more failures. Scan errors and reallocation checks were a better indication that a drive would fail. If there is even one scan error, there is a significantly higher rate of failure within 60 days. Drive failure is important to deal with, as over 90% of all new information is stored on hard drives and other magnetic media.

MP3's Loss, Open Source's Gain. Eliot Van Buskirk. Wired. February 23, 2007.

Alcatel-Lucent was awarded $1.52 billion by a federal jury in an MP3 patent infringement suit against Microsoft, even though they licensed the software from Fraunhofer/Thomson, the industry-recognized licensee of MP3. The result will be appealed. But if upheld, it could start an all-out licensing / lawsuit campaign. It could possibly extend to all companies involved with MP3 encoding or playback. This uncertainty could move the industry away from MP3, and that could be beneficial for open source software or other formats. Some of these are:

• Ogg Vorbis, (open-source with better sound quality, but royalty questions)
• AAC (based on MPEG-4, it has greater fidelity at higher compression rates)
• Window’s Media format

But the patent questions could extend to other software as well, which could influence the use of open source software. [See James Hilton’s speech at OR2007]

Why organizations need to archive email. White paper. GFI Website. February 22, 2007.

Emails have become the electronic substitutes of legal business documentation and the correspondence constitutes a record which has a retention period. A ‘true’ email archiving system will automatically extract and index the content of the message and attachments from emails, stores the email in read-only format so it cannot be changed. This also decreases the online email storage. Backups and archives are not the same; backups are to guard against system failure, while archives protect the data so it can be accessed when needed and can restrict access to authorized users. Email archives are important for compliance issues, litigation support, and storage / knowledge management. An email archive should have:

• Minimal user intervention and automatic processing
• Ability to index, search, and retrieve records and attachments
• Data retention selection and control by policies
• Security and authenticity which must include ability to restrict access
• End-user and management access to archives
• Support for multiple messaging platforms

Medieval Stained Glass in Great Britain. AHDS Website. February 22, 2007.

A major digitization project has added over 18,000 images of stained glass windows in Britain to the Arts and Humanities Data Service (AHDS) website. The site now contains about 80,000 digital images. AHDS has a number of projects that involve digital preservation. One project is POSSE (Preserve Our Student Shows for Eternity) which is to provide long term access to student degree shows. Other resources available include: The Guides to Good Practice which provides recommendations for creating and managing digital resources. AHDS has conducted a Digital Images Archiving Study with JISC. Their deposit forms and guidelines are online, along with other preservation resources which are also available.
