UML Standard Profile
stereotype modelLibrary
This dependency means that the supplier package is being used as a model library associated with a profile. The client is a package that is stereotyped as a profile and the supplier is a non-profile package that contains shared model elements, such as classes and data types.
A model library is a stereotyped package that contains model elements that are intended to be reused by other packages. A model library differs from a profile in that a model library does not extend the metamodel using stereotypes and tagged definitions. A model library is analogous to a class library in some programming languages.
