It is essential for ensuring that nominated items fulfill the rigorous quality standards required for inclusion in the the Living Atlas of the World.

The package is mainly used by the Living Atlas Nomination App, it enables content contributors to evaluate their items against the Living Atlas criteria before submitting them for nomination.
