KermetaExecutable Metamodeling

Language

• Initiated by Franck Fleury in 2005 within IRISA – Triskell team

• Kernel Metamodeling

• Execution platform under Eclipse

• Open-source language (EPL)

Outline• Context definition• Overview• Goals• Model Driven Architecture Context Adhesion • Basic Concepts• Concepts in Action• Cumulative View

• Capabilities• Limitations

Context definition

• Java – lack MOF concepts (associations, multiplicities)• OCL – UML support• Action Semantics - different levels of abstraction

Kermeta – Executable Metamodel

• Basic principles in Eclipse context

• Behavior aspect principle

Kermeta Goals• Intuitive

• EMOF compatible

• Eclipse

• Model transformation• EMOF

• Traceability

• Model testing

• Model prototyping
