The basic synopsis is:
- 
mantle.product.category.ProductCategoryIdentis equivalent tomantle.product.ProductOtherIdentificationand is used to identify aProductCategorybased on anEnumeration. This is used to add a slug to aProductCategoryfor better human understanding of URLs and SEO, but can be used for other ways to identify aProductCategory(see this for examples). - 
mantle.product.store.ProductStoreDataDocumentis a join betweenProductStoreand aDataDocumentwith based on anEnumerationto specify what kind of join it is. See the PR for a couple different examples ofEnumerations.
