Each row is one action in the Value Moment Registry taxonomy, with the use case it rolls up to, its persona, its actor type, and descriptions of the action and the use case. Every action appears here even if it has no activities. valueActivities joins here on valueMomentId, so start from valueMoments and left join valueActivities to report actions with zero activity.
