Figure 1 - Element hierarchy in the IDM schema
The SERIE element is used to define the properties of a series.Product groups (PRODUCT_GROUPS) in which items (ITEMS) with similar features are combined are defined within the series. The items are automatically assigned to a series because they are child elements of the SERIE element. The DECISIONS elements are used to cross-series assign options to a series, product group or item via rules. It is also possible to assign actions (ACTIONS) to the rules defined in DECISIONS.
