Hiera is a key/value lookup tool for configuration data, often used in Puppet and created and built to make Puppet better and let you set node-specific data without repeating yourself.

Hiera’s hierarchical lookups follow a “defaults, with overrides” pattern, meaning you specify common data once, and override it in situations where the default won’t work.

The hierarchical data can be organised as JSON, YAML, and EYAML files.

This package installs the library for Python 3 of the hiera bindings to work with formatted hierarchical data.
