A Namespace “owns” the model elements that appear in it, and no model element may appear in more than one namespace.
The semantics of Namespace are those defined by UML [5, pp. 2-49, 2-68]. Elements appearing within the namespace, other than generalizations, must have unique names.
Subtypes of Namespace may restrict the types of model elements that the name space contains.
Specification
| Metaclass | Namespace |
|---|---|
| Extends | ModelElement |
| Description | A model element that contains (owns) a set of uniquely named model elements. Each contained element is owned by at most a single namespace. The concrete subclasses of Namespace constrain the type of elements the Namespace may contain. Namespace is an abstract metaclass. |

Language mappings
None. Namespace is an abstract metaclass. Package (rather than Namespace) maps to the more concrete notion of a C++ (or MS-IL) namespace.
