My name is David Clipsham and I have been employed as the File Format Signature Developer for a month, having previously worked as Customer Service Manager for the cross-government social collaboration tool, Civil Pages. My role is to improve the coverage of The National Archivesā PRONOMĀ file format registry. The internal and external signature information contained in the PRONOM registry is utilised by our file format identification toolĀ DROID, which is used to identify file formats so we can make informed decisions about the long term preservation of digital records.
My day is typically spent researching obscure and not-so-obscure file formats, picking through the internal code of each format and identifying the key characteristics that make the file format what it is, as described in Ross Spencerās recent blog post. I then recreate the key byte sequences, test them against sample files and upload them to PRONOM, ready for our bi-monthly signature release.
How do I focus my research?
