What is the checksum of a directory? Introducing sumfolder1

by @beet_keeper

In Fractal in detail: What information is in a file-format identification report? I describe the different ways of dissecting the information in a file-format identification report.

A file-format identification report is a data-rich artifact created during the processing of digital collections.

I had the idea of using this type of report to attach a checksum to an archival collection (files, and directories) as a whole. This is done using methods akin to a Merkle Tree, similar to those in source control systems such as Git, and Web3 Blockchain projects like Bitcoin.

This project is called sumfolder1.
