What is a Package in UML?

Packages in the Unified Modeling Language are used to group elements and provide namespaces for the grouped elements. A package can contain other packages, thus providing a hierarchical organization of packages.

Almost all UML elements can be grouped into packages. Thus, classes, objects, use cases, components, nodes, node instances, etc. can be organized into packages, thus making the organization of the myriad elements contained in a real-world UML model manageable.

In this example, there is a package containing a class diagram.
