ProductGroup constant
IRI for schema:ProductGroup
A ProductGroup represents a group of {Product}s that vary only in certain well-described ways, such as by {size}, {color}, {material} etc.
While a ProductGroup itself is not directly offered for sale, the various varying products that it represents can be. The ProductGroup serves as a prototype or template, standing in for all of the products who have an {isVariantOf} relationship to it. As such, properties (including additional types) can be applied to the ProductGroup to represent characteristics shared by each of the (possibly very many) variants. Properties that reference a ProductGroup are not included in this mechanism; neither are the following specific properties {variesBy}, {hasVariant}, {url}.
