Specifications
Specifications for products are stored in several different places in the product data model.
-
Global specifications
Specifications that are global across the entire product repository are stored in the global specifications folder under
Product Repository/Lookups/Global Product Specification Lookups(relative to the product repository).These specifications are typically stored as lookup tables where a key and a set of predefined values are defined.
-
Classification specifications
For each classification scheme there is typically a list of specifications associated with each category. These are the specifications that make it possible to compare all products present within a category made by different manufacturers.
These are also the specifications normally used for navigated or faceted search.
-
Type specifications
There is a close relationship between a product and its type and therefore there are three pieces of specification information available on types:
-
Specifications in the form of keys or keys + values (lookup tables).
-
Specification options that narrow down the lookup table options for subtypes.
-
Specification default values that contain values for specification. All products of the given type will have those values.
-
-
Product specifications
Specifications that are unique to specific products can be stored under the product itself. Typically, most specifications will be on the product type.
