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. I agree, but I fear this this ‘absolute’ format obsolescence is a poor proxy for the real problem, which is to ensure that our […]

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 […]

A couple of weeks ago we announced the market research into the potential of Digital Preservation Practices and Tools outside its traditional market Libraries and Archives.

At the hackathon it was clear that the identification discussion started by Fido represented an archetypal example of why this community wants to work together. No matter what the institution, whatever the context or workflow, we all need reliable tools for identifying files and formats. Of course, reliable identification requires reliable identifiers, and so the […]

During the past couple of weeks, there have been some thoughtful and well-informed discussions about Fido, Droid, Pronom, and file format identification in the comment stream of this blog.  They make interesting reading. In a recent comment, Shaun Zevin raises some points about the algorithmic complexity of the Droid and Fido pattern matching. From the […]
