In a UML component diagram, each element on the diagram has properties. To see the properties of an element, right-click the element on the diagram or in UML Model Explorer and then click Properties. The properties appear in the Properties window.

Properties of Elements
| Property | Default | Element | Description |
|---|---|---|---|
| Name | A default name | All | Identifies the element. |
| Qualified Name | Namespace :: Name | All | Identifies the element uniquely. A component or type's name is prefixed with the qualified name of the package that contains it. A part or port's name is prefixed with the qualified name of the component that owns it. |
| Work Items | 0 associated | All | The number of work items associated with this element. To associate work items, see Link model elements and work items. |
| Description | (none) | All | You can make general notes about the element here. |
| Color | (default for the type) | Component, Part, Delegation, Part assembly | The color of the shape. Unlike other properties, this is the color of the shape rather than the model element that the shape displays. |
| Is Indirectly Instantiated | True | Component | The component exists only as a design artifact. At run time, only its parts exist. |
| Is Abstract | False | Component | The component definition can be used only as a generalization from which other components can be specialized. |
| Visibility | Public | Component, Part, Port | Public - globally visible. Package - visible within the package. Private - visible within the owning component. Protected - visible to components derived from the owner. |
| Type | Type on creation | Part Port |
The type of a part is a component or class. The type of a Port is an interface. |
| Multiplicity | 1 | Part Port |
Indicates how many instances of the specified type form part of the parent component.1 - exactly one.0..1 - one or none.* - a collection of any number.n..m - a collection of from n to m instances. |
| Is Behavior | False | Port | If true, messages to this port are handled by activities or operations that are described as part of the component, instead of its parts. |
| Is Service | False | Port | If true, this port is part of the published interface of this component. |
| LinkedPackage | Model | Diagram | The default namespace for elements added to this diagram. |
