description
This presentation, part of an extensive practical tutorial on logical and bit-stream preservation using Plato (a preservation planning tool) and EPrints (software for creating digital repositories), places the process of managing formats and risk analysis in the EPrints repository interface. The presentation was given as part of module 4 of a 5-module course on digital preservation tools for repository managers, presented by the JISC KeepIt project. For more on this and other presentations in this course look for the tag ’KeepIt course’ in the project blog http://blogs.ecs.soton.ac.uk/keepit/

• Bit checking & checksum calculation
• What is the type of file, is the file valid?• Is the file at risk of not having an editor/reader?• Is there a better format available? Lossless or Lossy?
• File migration to avert risks found by analysis.• Movement of file to new storage.
The Preservation Process
Preservation - AnalysePreservation - Analyse
• What is the type of file, is the file valid?• Droid is a good classification tool for this.
• Is the file at risk of not having an editor/reader?• Functionality is being developed in PRONOM technical registry.
• Is there a better format available? Lossless or Lossy?.

File Format Analysis

• Is the file at risk of not having an editor/reader?• Functionality is being developed in PRONOM technical registry.
• Simple SOAP web service
• Takes file format identification id’s, hands back risk score. • Breakdown of risk score may also be available in future releases.
• A stub you can download and run providing this functionality before the official release with mock up risk scores is available at http://preserv2.googlecode.com

• Handled by our storage manager and reported back via the preservation interface.
• Parallels can be drawn with storage, in that we are integrating with and utilising currently available services to perform our analysis.• Processing of the results leads to a powerful interface which tells us many things about the repository ecosystem and it’s future.
• Future plan is to utilise further web based services to ensure information remains comprehensive and up to date set, 0day digital preservation.
