Object model

While the structural metamodel centers on classes and their static structures, the object diagram metamodel enables the representation of how these classes are instantiated into objects and interact with each other. The Object class in the metamodel represents the instances of a Class from the structural metamodel. Its object attributes are defined using the AttributeLink class, and associations with other classes are established using the LinkEnd class. In BESSER, the object diagram metamodel is primarily utilized for conducting validations or tests on the model. For instance, validating OCL rules over instances of the B-UML model.

Note

The classes highlighted in green originate from the structural metamodel.

Supported notations

To create an object model, you can use any of these notations:

• Coding in Python Using the B-UML python library

• Using PlantUML to design you object model
