What is a “generic” geographical indication?

If the name of a place is used to designate a particular type of product, rather than to indicate its place of origin, the term no longer functions as a geographical indication. For example, “Dijon mustard”, a kind of mustard that originated many years ago in the French town of Dijon, has, over time, come to denote mustard of that kind made in many places. Hence, “Dijon mustard” is now a generic indication and refers to a type of product, rather than a place.
