Item type (for recommendation) selection

The Item type (for recommendation) is similar to a class ID in eZ Publish. It defines a number corresponding to a given type of content. If you attribute the number “2” as Item type for recommendation to multiple classes e.g. article (main-page) and article (sub-page) then both classes are treated as one type by the recommendation service.
