Quality Assurance Tools and Techniques

 

Purpose

Quality assurance is a crucial step in the digitization process. Ensuring quality of (semi) large collections whether produced by outsourced services or created in-house by multiple persons can be an overwhelming prospect. The following guide will show how you can use tools and techniques for confirming digitization specs and help identify possible errors or corrupt files using automated tools.

 

This guide will show how to:

  • Confirm all files are unique (no duplicates)

  • Filenaming schema is consistently used

  • All files are valid and well-form

  • Confirm received the expected number of digital objects (completeness)

  • Confirm technical specifications

  • Help identify possible errors or corrupt files

  • Batch embed metadata – to ensure files contain some descriptive information directly, best practice is to embed basic metadata such as title, source and copyright. See guide for using exiftool commands or other tools, https://tinyurl.com/7xz3hbm.
  • Batch rename files (command line) -- If you need to rename files to match project filenaming conventions, see Steps to batch rename files
  • Transfer large number of files – Best practices recommend copying digital files from an external drive to a separate location (e.g. project server). This provides a backup of source files before any processing. Both utilities provide detail status of transfer and will retry transfers until done, in case of interruption.
