To represent an instance of a class in a UML Object Diagram, the standard notation is to specify the instance name followed by a colon and the class name, and then list the attribute values within the compartment.

The class definition forCompanyspecifies that there is one attribute,name, of typeString.

An instance ofCompanywhere thenameattribute has the value "OMG" would be shown as follows:
