The latest version of siegfried, 1.5.0, has just been released. The big change is support for a second identifier type, freedesktop.org’s Shared MIME-Info specification.
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. […]
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 […]
Overview For decades memory institutions have put effort into dealing with pieces of the digital preservation puzzle. Unfortunately this has also resulted in quite a lot of fragmentation – solutions in place in different institutions and countries are not easily reusable in others. After carrying out extensive consultations with the European Commission a set of […]
Overview This webinar looked at the techniques the National Archives New Zealand is developing to aid in the analysis of collections and also support the dissemination of the skill set that will help non-digital-preservation specialists continue to support the organisation in its ability to process born-digital collections. In 2013, the Archives New Zealand’s worked on analysing the content […]
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 […]
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 […]
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 […]
