License:Apache License 2.0


Siegried is a file format identification tool that, like DROID and Fido, is based on PRONOM. However, it uses a different pattern matching algorithm that offers different strengths and weaknesses to those other PRONOM based tools. A detailed description of the tool and why it was created can be found in this blog post. Besides, there is a more detailed description in terms of functionality on the Github Page of Siegfried.

Siegfried was first publicly released the 28th february 2014 in version 0.1.

User Experiences

  • ZBW:
    • The command line tool is very easy to handle.
      The default output is yaml. This can be changed to csv or json.
      • Usual command: sf file.ext (will output in yaml)
      • Change output to csv: sf -csv file.ext
      • Change output to json: sf -json file.ext
    • It is also possible to save the output in an external file:
      • sf file.ext >output.yml
      • sf -csv file.ext >output.csv
      • sf -json file.ext >output.json
