System imaging – dumping the permanent storage of a computer system to re-run it in an emulator – is a viable option to preserve complete digital environments. These include complex digital artefacts, famous persons machines, electronic lab books of natural sciences research or software and hardware development environments of software companies, to mention just a […]

In the middle of November 2012, the first OPF Hackathon on Emulation took place in Freiburg, Germany. It brought together practitioners from different national libraries, library information services as well as a couple of researchers in the domain. The aim of the three-day Hackathon was to work on practical use-cases and real-live challenges stemming from […]

Emulation is getting more and more relevant in digital preservation and thus got its first full-day workshop at this years iPRES in Toronto on 1st October. While emulation is now widely accepted as a necessary access strategy, mature software frameworks and workflows are still missing. The workshop provides the opportunity to present latest research results, […]

Emulation as a preservation strategy for memory institutions has been researched since Jeff Rothenberg’s article in Scientific American Magazine (1995). The strategy relies on emulating hard- and/or software that has become obsolete. Rendering a digital work by emulating the original platform for which it was originally created has the preservation benefit of recreating the (near)original […]

In this blog post I'll be dusting off some old stuff for a change. The occasion for this is the following question, posted by Paul Wheatley on the Libraries and Information Science Stack Exchange website a few days ago: What preservation risks are associated with the PDF file format? This reminded me of a report […]

Hardware emulators are software implementations of (past) computer architectures to reproduce original environments for a wide range of purposes. Most emulators and virtual machines are programmed for local access, which means that they are installed on the machine the user is working on. The screen output gets redirected into a window or the whole screen […]

We have recently started some research at Archives New Zealand  to investigate the best approaches for appraising, transferring (where relevant) and preserving databases. As part of this research we will be undertaking case studies of a number of databases. The case studies will involve a number of aspects including where possible testing one or more […]

Beginning of this year we reported on first results of a joint Archives New Zealand and University of Freiburg data recovery project of a set of 5.25 inch floppy disks from the early 1990s. After recovering the raw bitstreams from the floppy disks with a special hardware device the resulting image files were sent over […]

I spent last week at the Open Planets Foundation Database Archiving event at the Statens Arkvier in Copenhagen. There was a good mix of people, both technical and practicioners, with some informative presentations, and it was interesting to see the different approaches to the problem. To my mind there appeared to be two distinct classes […]
