A business entity type is a conceptual entity representing the legal form, the size, the main line of business, the position in the value chain, or any combination thereof, of a gr:BusinessEntity. From the ontological point of view, business entity types are mostly roles that a business entity has in the market. Business entity types are important for specifying eligible customers, since a gr:Offering is often valid only for business entities of a certain size, legal structure, or role in the value chain. Examples: Consumers, Retailers, Wholesalers, or Public Institutions
