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 Business Entity. 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 Offerings are often meant only for Business Entities of a certain size, legal structure, or role in the value chain. Examples: Consumers, Retailers, Wholesalers, or Public Institutions
