For anyone dealing with a relatively small number of records, compared to say an internet or data archive, a reasonable process for ingest of material into your digital preservation system might be: 1. Process files with a file format identification tool 2. Per 1. process files with a file format validation tool 3. Per 1. […]
At my workplace, we write a lot of small scripts to encode preservation workflows. These scripts pipeline simple actions like munging metadata, moving files about, and calling other tools such as Tika and ImageMagick. Often these actions are conditional on the format of the file being processed: for example, we only want to run Tika over the formats for […]
This is the second blog inspired by my visit to colleagues at National Library of Australia, last August. The first, discusses a federated approach to better incorporating custom signatures into the PRONOM signature base without modifying PRONOM. The essence of the blog, however, still centers around how the community can create signatures for itself, and […]
Presented here is a tool that will create a 'rogues gallery' out of any digital collection for which you have a DROID report for (alternatively, soon, a Siegfried report for). The tool was presented at a recent OPF Webinar, Preservation in Practice: Archives New Zealand; slides here. And was created by myself and Andrea K. […]
Abstract() This blog discusses what we have available in our toolkit for contributing more signatures to PRONOM for the benefit of the digital preservation community. It also discusses the potential issues we need to work around in the short time we have between controlled PRONOM releases. The blog outlines an idea for a temporary, federated […]
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 […]
We’ve been doing legacy disk extracts at Archives New Zealand for a number of years with much of the effort enabling us to do this work being done by colleague Mick Crouch, and former Archives New Zealand colleague Euan Cochrane – earlier this year, we received some disks from New Zealand’s Department of Conservation (DoC) which we successfully imaged and […]
In this post I'll be taking a look at format identification of PDF files and highlighting a difference in opinion between format identification tools. Some of the details are a little dry but I'll restrict myself to a single issue and be as light on technical details as possible. I hope I'll show that once […]

I thought OPF members might be interested in this UK Web Archive blog post I wrote on format identification and validation of our historical web archives: How much of the UK's HTML is valid?
The problem We have a large volume of content on floppy disks that we know are degrading but which we don't know the value of. Considerations We don't want to waste time/resources on low-value content. We don't know the value of the content. We want to be able to back up the content on the […]
