I read Johan's fascinating post this morning about the obsolescence of Quattro Pro formats. In the post he included a set of Quattro Pro spreadsheets and invited others to try to access them using the original software or an old version of Excel. Luckily I have an old version of Quattro Pro available so I thought I'd […]

While browsing ArchiveTeam's File Formats Wiki earlier this week, I came across some entries I created there on Quattro Pro spreadsheets two years ago. At the time I had also contributed some old Quattro Pro for DOS spreadsheets (here and here) from my personal archives to the OPF format corpus. Seeing those files again, I […]

Earlier this week I had a discussion with some colleagues about the archiving of mobile phone and tablet apps (iPhone/Android), and, equally important, ways to provide long-term access. The immediate incentive for this was an announcement by a Dutch publisher, who recently published a children's book that is accompanied by its own app. Also, there […]

You can read the detailed information in my article (to be published soon). Basically I […]

As part of the scape project, we did a large-scale experiment and evaluation of audio migration using the xcorrSound tool waveform-compare for content comparison in the quality assurance. I did a presentation of the results at the demonstration day at the State and University Library, see the SCAPE Demo Day at Statsbiblioteket blog post by […]

Ok. I know what you're thinking. Do we really need another PRONOM-based, file format identification tool? A year or so I might have said "no" myself. In DROID and FIDO, we are already blessed with two brilliant tools. In my workplace, we're very happy users of DROID. We trust it as the reference implementation of […]

There is a trend in digital preservation circles to question the need for migration.  The argument varies a little from proponent to proponent but in essence, it states that software exists (and will continue to exist) that will read (and perform requisite functions, e.g., render) old formats.  Hence, proponents conclude, there is no need for […]

Some time ago Will Palmer, Peter May and Peter Cliff of the British Library published a really interesting paper that investigated three different JPEG 2000 codecs, and their effects on image quality in response to lossy compression. Most remarkably, their analysis revealed differences not only in the way these codecs encode (compress) an image, but […]
