UML Class Diagram

The dot shows that the model includes a Property of the type represented by the Classifier touched by the dot. This Property is owned by the Classifier at the other end.

The dot is to be drawn integral to the graphic path of the line, at the point where it meets the Classifier, inserted between the end of the line and the side of the node representing the Classifier.

Ownership of Association ends by an associated Classifier may be indicated graphically by a small filled circle, which for brevity we will term a dot.

Aggregation type, navigability, and end ownership are separate concepts, each with their own explicit notation. Association ends owned by classes are always navigable, while those owned by associations may be navigable or not.

Unified Modeling Language 2.5.1

Navigability notation was often used in the past according to an informal convention, whereby non-navigable ends were assumed to be owned by the Association whereas navigable ends were assumed to be owned by the Classifier at the opposite end. DEPRECATED.

UML Class Diagram

MagicDraw/Cameo: If you want to show a Property or Port listed both in its corresponding compartment on a Class or Block symbol and as the end of an Association in the same diagram, set the display option Show Association Ends As Attributes/Ports to 'all'

If the StructuralFeature is an Association end, the semantics are the same as for a CreateLinkAction ..., where the participants in the link are the object being acted on and the new value.
