Welcome to the Kea documentation

Kea aims to be a lightweight system to track file and transactional metadata and on top of this a simple scripting template system.


Kea aims to:

  • Track file metadata: Kea tracks file metadata based on a file’s sha256 checksum. This means that if you delete a file and recreate it the metadata wil still be there. Similarly, if you have multiple copies of a file, all of them will share the metadata. More..
  • Track relationships between files.: Relationships between files are tracked by storing a record with the checksums of the related files. For example if one file is created from another file, Kea creates a record with the checksums the two files (and additional information). You can later query the database for any transaction related to a certain file. If you consequently store transactions (as part of your scripts), you will have full provenance. Again, by storing checksums, you can move files around without losing information.
  • Provide simple script templates: File and transaction metadata can be stored individualy per file and transaction. However, to make things easier, Kea provides a simple templating system where you can build a template, inidicate what the in-, and output files are, and upon exeuction, Kea stores the transaction automatically. Additionally, the script engine provides the ability to run across many files at once.
