In a recent blog post, Gary McGath, JHOVE’s former developer and maintainer, questioned whether JHOVE maintenance had ceased. While this is not the case, he is right in pointing out that the Open Preservation Foundation’s resources are limited and that we have other commitments. JHOVE is governed by a Product Board who meet once a […]

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 […]

Abstract: Downloading an object over the internet through a standard web-browser is a mechanism that is ‘less-than-optimal’ for the delivery of archival objects. Download of objects will not preserve the file-system metadata of the object. Tools like Wget can do this, but do we want the same behavior of the browser? On answering that, do […]

A significant part of the work in digital preservation field is dependent on various software tools. Categories such as identification, validation, characterization, migration and emulation have thus received significant effort over the last years. While without doubt achievements have been made, it is quite hard to quantify the successfulness of the work which has happened. […]

Ever since I started working on digital files validation, it seems as if nobody cares about MP4, MP3 and AVI files. Some people suggested to use MediaInfo or Ffmpeg to proceed their files validation. I may be wrong, but it doesn’t sound enough for me. With a command line, leading to the file conversion, I […]
