We are integrating ATG 10.2 with Endeca 3.1.2. We are going to have 10 different sites with different catalogs but the products and sku's can be shared across the catalogs.
To meet this requirement we are using CustomCatalogVariantProducer and UniqueSiteVariantProducer components to create multiple endeca records for each variant that is available.
The question that we have is if a particular category is shared among multiple catalogs, do we need to have separate product.category dimension, one for each catalog that is indexed or will the CategoryToDimensionOutputConfig component take care of this by having all the possible combinations as dimension values in one dimension called product.category.
Please share your thoughts on this and correct me if I am wrong.
