In UML modeling, you identify the classifiers in your model by giving them unique names. Each classifier has a fully-qualified name that consists of parent name, which is the namespace that contains the element, and the name of the element itself. The fully-qualified name is the concatenation of the parent name and the name of a classifier; for example, ParentName::ClassifierName. You can display only the classifier name or display the fully-qualified name of a classifier.
