Advanced OO Modelling: Metamodels and Notations for the New Millennium. Brian Henderson-Sellers   View Paper (PDF)   Return to Conference Tutorials Abstract Building an object-oriented model requires knowledge of process and techniques; whereas representing the model requires the use of a notation underpinned by a rigorous definition. Today this usually starts with a metamodel. Together, the metamodel and the notation are known as a "modelling language". DiSC'03 © 2003 Association for Computing Machinery
