# Description

The default_inertia attributes of the Articulation,
RigidObjectCollection, and RigidObject data asset classes did not
specify in what coordinate frame the tensors should be provided. This PR
addresses this, and addresses some minor inconsistencies across the
default_inertia docstrings.

## Type of change

- This change requires a documentation update
