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 […]

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 […]

Before I started with format editing, I realized that it would be very simple to implement cool URLs for file formats.

Tapestry does […]

Last week I was at home in bed for four days with a bad back. I could not really type, but I could browse, so I did have an opportunity to catch up on the recent OPF blog entries. I was particularly interested in the discussions regarding a new Format Registry. I am an amateur […]
