Detailed description

As part of the development of the preservation strategy there is also a need to map duplicates and check for authenticity and integrity of files.  Part of this process is looking at checksumming.  This involves using tools such as Fastsum:

and looking at how this information is stored and built into the business workflow.

'md5sum' could also be used through Cygwin command line on a Windows environment to provide (for free) checksums of files.  This could be used in combination with 'find' and 'xargs' to generate a manifest.

It may also be worthwhile considering BagIt which enables a separation between the data to be manifested and the manifest (metadata) itself whilst maintaining a link between these files.

Other interested parties
Any other parties who are also interested in applying Issue Solutions to their Datasets.

Possible Solution approaches

  • testing out preservation planning tools
  • suggestions of what worked/what didn't work from other developers/practitioners


This is part of a wider attempt to develop a robust preservation strategy to a small but growing digital repository in an underfunded but large local authority.  The dataset is a small sample from a larger collection of digital assets with a variety of file types, descriptive metadata etc.
