# CategoriesSource

The **CategoriesSource** store maps parent/child nodes to categories.
It is indexed by **AsOfDate** and **Node**.
It is an isolated store and not part of any cube facts.

This store is only created if the property `categories-hierarchy.enabled=true` is set.  It is used to build the [Categories](./categories) store.
