How is OAIS evolving?

After some reviews about the implementation of the OAIS standard in the real world some are wondering what are the benefits of the concept over the long run:

Tenet of OAIS approach (ISO-14721)
- Self-describing / self-containing information packages contain content and contextual metadata without dependency on databases or technology through time

• Interoperability over the long-term and economic benefits in heterogenous digital environments
• Longevity of understandability of business information independent on technology (interfaces)

• more effort & complexity to perform
• Definition of the container to submit the package (package type, or SIP)
• Additional step prior to ingest where the database scheme is validated before submission (package)
• No (or very few) proven use cases where advantages of standardization had a substantial impact on economics or interoperability

Some experts from the DCC and DPC in UK have written about this:

Interesting also the chapters in the thesis of Anthea Seles from the University College of London.

Preservation costs survey (US)

Professor William H.J. Hubbard from the University of Chicago Law School recently concluded his Preservation Costs Survey and the results are now available.

go to:
download of executive summary and full report (for free)

The survey “is the first, and to date only, systematic effort to measure the extent and costs of preservation activity across a broad sample of companies,” and collected data from 128 companies, “including companies of all sizes and from a broad range of industries.”
The Survey generated conservative estimates of costs that are solely attributable to preservation obligations (scheduled records).
somehow a restricted scope of ESI.

No surprise, one of the results: Preservation of email and hard drives is the most common source of problems.

NARA report about eArchiving

Archiving of electronic records--in fact, archiving of any type of record--continues to be problematic within federal agencies, says the National Archives and Records Administration in a report drawing its conclusions based on agency self-assessments.

Information lasts only so long as someone cares about it ...

The complexity necessary for long-term preservation of digital records contributes to the potential for failure. Consider the vulnerable points, colloquially known as a chain of weak links:

Gordon Hoke on KM world
Removable media—There is no way to assess the longevity of removable media, including tape and laser-written disks (CD, DVD, Blu-ray, WORM, etc.). There are too many variables. The standard way of testing media is “accelerated aging,” but only the future will prove its accuracy. There are no standards for quality, and it is difficult to impossible to consistently identify the materials and manufacturing processes that produced a shipment of disks. Controlled temperature and humidity affect the stability of a disk’s substrate and dyes, but storage environment is only half a disk’s life cycle. Even for a disk made of high-quality materials, who can verify the conditions and duration under which the disk was transported and warehoused before use?
Hardware obsolescence is obvious and visible to all who have reached adulthood. Floppy disk drives (5.25-in. or 3.5-in.) are difficult to find, to say nothing of players for ZIP, Jazz and other proprietary format media. In 1991, Sony advertised a 12-in. optical disk guaranteed to last 99 years. While the verity of that claim will be revealed in 2090, not even museums are likely to have a compatible disk player.
As operating systems evolve, they have limited compatibility with their ancestors. Can a PC running Windows 7 read files created under CP/M? Can today’s IBM Power System OS consistently extract files written on a s/38 from 1979 or a system/3 from 1969?
Application software becomes obsolete as well. Consider the boneyard of former market leaders: VisiCalc, WordStar, Wang word processing and countless others. Microsoft stopped supporting Office 97 about 10 years after its release.
Output drivers—Retrieving old records also depends on being able to display and/or print content. Even with legacy CPUs, OSes and application software, the period monitors, printers and the software that drives them may be unavailable or inoperable.
Encryption and password protection—Long-lived records, including health records, often require security and privacy protection. Maintenance of passwords and decryption capabilities loom as additional impediments to the retrieval of old records.

Project KEEP (Keeping Emulation Environments Portable)

KEEP (Keeping Emulation Environments Portable) will develop an Emulation Access Platform to enable accurate rendering of both static and dynamic digital objects: text, sound, and image files; multimedia documents, websites, databases, videogames etc.

The overall aim of the project is to facilitate universal access to our cultural heritage by developing flexible tools for accessing and storing a wide range of digital objects.
