The schema of a catalog refers to the structure and organization of the catalog. A schema consists of categories and descriptors. A category classifies items, a descriptor describes items or categories.
There are two types of descriptors:
Base descriptors apply to all items or services in the catalog. 'Supplier' is an example of a base descriptor.
Local descriptors apply only to items within a specific category. 'Ink color' is an example of a local descriptor for the category of 'Pens'.
