is_variant_of
Use it like this:
- [ #is/_variant_of :: ProductGroup, ProductModel] or
- [ is_variant_of :: ProductGroup, ProductModel]
Indicates the kind of product that this is a variant of. In the case of ProductModel, this is a pointer (from a ProductModel) to a base product from which this product is a variant. It is safe to infer that the variant inherits all product features from the base model, unless defined locally. This is not transitive. In the case of a ProductGroup, the group description also serves as a template, representing a set of Products that vary on explicitly defined, specific dimensions only (so it defines both a set of variants, as well as which values distinguish amongst those variants). When used with ProductGroup, this property can apply to any product included in the group.
Relation describes that: [ #has_/domain :: Product, ProductModel] ( #has_/name :: is_variant_of) ( #has_/range :: ProductGroup, ProductModel)
[ #is_/inverse_of :: hasVariant]
