Using the attribute dictionary
Before you create products in your store, create attributes. Attributes are
characteristics of a product such as size or color. There are two types of attributes, attributes
with predefined values, and attributes with assigned values.Attributes are shared
across products. If you assign an attribute to a product, and then change the attribute, the
attribute is also changed in all the products that it references. Both types of attributes are
creating by using the attribute dictionary.
