Repository stores specific values of an artifact, different for 
various artifact's classes, and artifact themselves. Artifacts are archived with
a special attribute named md5hash.
To learn more about artifacts visit archivist-package.
Bug reports and feature requests can be sent to https://github.com/pbiecek/archivist/issues
For each artifact, md5hash is a unique string of length 32 that is produced by
digest function which uses a cryptographical MD5 hash algorithm.
The md5hash of each artifact that is archived in the Repository is also saved
on the Repository along with the artifact's Tags - see Tags. It enables to distinguish
artifacts in the Repository and facilitates searching and loading them.
