5. Objects Do not exist alone 0…M UML class Do not exist alone 0…M UML class

6. Properties Attributes and Relationships about the Feature or Object. Simple Properties

7. Properties Uni-directional association used when the relationship refers to a feature. Composition Aggregation used when the property describes an attribute(s) with cardinality = many.

8. Properties Standard UML association class is used to describe attributes about the relationship.

9. Properties Inheritance - The specialized feature inherits all of the properties of the more general feature.

18. Property Type 1.Created property type to define the relationship. 2.If the relationship points to an object, include object in the property type 3.If the relationship points to a feature, include attribute xlink:href.
