I’ve finally had time to consider David Rosenthal’s response to my argument in favour of format normalisation as a preservation strategy. While I largely agree with his position on format obsolescence (with some caveats I’ll return to in a future post), we do appear to disagree on a more fundamental level – on what it […]

At Freiburg the software archive has been extended: The abandoned system disks and documentation of Mac OS 7 from 1991 is a good start for a non-X86 branch of operating systems and applications. As the data survey in Archives New Zealand and the legacy of research institutions demonstrate, there is demand for other original software […]

The idea of migration by emulation assumes the injection of digital objects into their native environments where they can be migrated using environment- and object native applications and the extraction of the resulting migrated objects from the corresponding environments after the process is finished. The injection/extraction requires the usage of containers (like floppy devices), which […]

We’ve been working away on defining and solving preservation problems at the 3 day AQuA Mashup event in Leeds. Today we wrapped up some new technical solutions and documented what we learnt. I think its not unrealistic to claim that most of the preservation issues and challenges have actually been centred around pretty straightforward problems. […]

After having emulators conceptually established in digital preservation and having proved to run them actually for different original environments, the next logical step is their preparation for main-stream. To deploy emulation in e.g. Migrate workflows is a bit more complex than to wrap a simple converter like ps2pdf but might earn a much wider covering […]

Attendees at the first AQuA Project event in Leeds, UK, are spending 3 days tackling some preservation issues with their digital collections. We’re trying to answer questions such as: What does my digital collection consist of? What preservation risks does it face? Are any of the files broken? Are there any duplicates? We’re mid way […]

The OPF is collaborating on an exciting new project that is aiming to enhance our ability to validate the condition of digital content. The AQuA Project is running two mashup events in April and June that will focus on developing our understanding of collection issues, such as bit rot or digitisation errors, and develop ways […]

Dave Tarrant of Southampton University (with co-authors Steve Hitchcock and Les Carr) has recently published a paper in the International Journal of Digital Curation: “Where the Semantic Web and Web 2.0 Meet Format Risk Management: P2 Registry“. This describes the work Dave has done on creating a Linked Data registry (‘P2’) to hold information about […]

Emulators are a crucial building block in digital preservation strategies. They are supposed to bridge the widening gap between past and current digital environments. Like every other software they need to be updated from time to time if the actual environment they are running in changes. But, independent of those updates, the internal structures created […]

After raising this topic in PLANETS and us evangelizing at the OR2010 it was great to see quite a bit of practical approach to software archiving at Archives New Zealand. When working in the area of long-term access to digital objects (and when your objects are anything more complex than your basic image file) a […]
