The National Archives at Kew are unveiling the latest evolution in digital preservation technology, with the release of PRONOM 4.
The new technical registry system addresses the single most challenging problem facing electronic record keeping: the rapidly changing IT sector. Viewing a single file in a given format requires a complex network of technical dependencies. But from year to year, software, hardware and operating systems are altered as new technologies are developed and old ones become obsolete.
Understanding this complex network of technical dependencies lies at the heart of any archiving programme for electronic records.
Enter PRONOM 4.
First developed by The National Archives in March 2002, the PRONOM series is tailor made for electronic records management. With the release of the upgraded PRONOM 4, the system not only contains an enhanced database with detailed information on the technical dependencies of electronic records, but includes a new downloadable tool - DROID (Digital Record Object Identification) - which automatically identifies formats using a file's binary signature.
DROID detects the addition of new binary signatures to the PRONOM database and automatically downloads updates via the Web. This keeps the system up to date with the latest technical information.
Adrian Brown, head of Digital Preservation at The National Archives said: "the challenge for any archivist is not only to understand the nature of a file's technical dependencies, but also to continually monitor changes in those dependencies, because those changes threaten the continued accessibility of electronic records.
"Automation is essential when processing those changes in large volumes of records - it is simply not feasible to undertake manual processing and cataloguing for millions of files. "
In order to maximise the value of PRONOM, TNA welcomes the input and participation of all interested parties. This does not require major resources: a very practical way to contribute is by submitting new information for inclusion in the database. In particular, TNA is keen to collaborate with all who have specialist knowledge of particular types of electronic record, such as scientific data formats and software tools. Information can easily be submitted using an online form, and all sources are fully acknowledged.
PRONOM has been developed as a resource to support both TNA's own digital archive, and for the wider international community. For this reason, PRONOM and the new DROID tool has been made freely available on the web (www.nationalarchives.gov.uk/pronom/), where users can search its content, generate reports, and even submit new information for inclusion.
