Percipio is a small tool I have developed. You can find the tool here https://github.com/blekinge/percipio I will make a proper release soon, especially if anybody shows any interest. It has been heavily inspired by the now not-developed closed sourcec tool TrID http://mark0.net/soft-trid-e.html File signatures have traditionally been created by hand. This comes from the traditional […]

Memory institutions planning to realise a digital preservation strategy and setup suitable systems face the problem of missing evaluation components. A number of tools for object characterization, migration or rendering in emulated original environments are available or being developed at the moment. But, to evaluate or compare them a proper set of sample objects is […]

A couple of months ago I reported on this blog that the OPF was beginning a project to investigate options for a new approach to file format registries.  We’ve just released the second report of this activity: “A New Registry for Digital Preservation: Conceptual Overview“. (330kB PDF); It explains our vision of a ‘registry ecosystem’ […]

http://www.dev8d.org/ For preservation and beyond, broad and reliable format identification has proven to be a critical shared problem across many institutions. Recent discussions on the OPF blogs have illustrated this point, and showed that we all like using DROID and Fido but would also like to improve them. The main challenge is to improve the coverage and quality of the signature […]

After Ross’s post, I thought I’d better follow up on my format registry thoughts and show you all my response to Adam’s challenge. Using my weapon of choice, I was able create and populate a web site for collaboratively editing PRONOM data in just over one week’s worth of my spare time (six days FTE). […]

As David Rosenthal pointed out, as long as there is a piece of commercial software or an open source project capable of accessing a format, it cannot be considered truly obsolete.

Somewhat later than planned, I present here my final installment on the Format Registry Challenge. During this “experiment” I have spent some time becoming acquainted with the Git version control system, working with both Windows msysgit and the Eclipse Git plugin EGit. One result is that my prototype registry source code (and associated war archive) […]

I just wanted to point out a very interesting discussion on format obsolescence: The Half-Life of Digital Formats, A Puzzling Post From Rob Sharpe and Rob Sharpe’s Case For Format Migration. I think this is a very important issue, and I think we must address it as it cuts to the core of what the […]
