The following illustration shows a simple dimension mapping example that uses a combination of generation methods. The sections after the illustration describe the mapping behavior in the example.
The Red and White property values have matching Red and White dimension values specified in the dimension hierarchy. These property values are mapped to the Red and White dimension value IDs, respectively. Bottles B and C are tagged with the Red dimension value ID, and Bottle A is tagged with the White dimension value ID.
The Sparkling property value does not have a matching dimension value in the dimension hierarchy. The Wine Type dimension is set to Must Match, so this property is ignored and a warning is issued. As a result, Bottle D does not get tagged with a dimension value ID from the Wine Type dimension.
There are no dimension values explicitly defined in the dimension hierarchy for the Country dimension. However, this dimension is set to Auto Generate, so all three of the Country property values (USA, France, and Chile) are mapped to automatically-generated dimension value IDs.
Bottle A is tagged with the auto-generated ID for the USA dimension value. Bottles B and D are tagged with the auto-generated ID for the France dimension value. Bottle C is tagged with the auto-generated ID for the Chile dimension value.
The Crisp property value has a matching dimension value specified in the dimension hierarchy, so the Crisp property value is mapped to the Crisp dimension value. Bottle A is tagged with the Crisp dimension value ID.
The other three property values (Elegant, Full, and Fresh) do not have matching dimension values in the dimension hierarchy but, because the Body dimension is set to Auto Generate, these three property values are mapped to automatically-generated dimension value IDs.
Bottle B is tagged with the auto-generated ID for the Elegant dimension value. Bottle C is tagged with the auto-generated ID for the Full dimension value. Bottle D is tagged with the auto-generated ID for the Fresh dimension value.
Regardless of how they were generated, all of the dimension value IDs are included in the finished data that Forge produces for indexing.
