At Archives New Zealand we were finding ‘WAVE’ files becoming a bottleneck of one of our ingest processes.

With ‘double the magic’ there was a lot more for us to explore as analysts, and fingers crossed this release (a refactor) of my SQLite based analysis tool will help with that exploration.

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 […]
