2. Rational Unified Process (RUP) - Model Driven Architecture (MDA)
Code generation

Domain model
Analysis model (Entities)
Design model
Runnable program

Platform Independent Model (PIM)
Platform Specific Model (PSM)

3. The 4 level metamodel stack of UML
Application data
Layer of world/data, the instance of the model
Domain (software) model
Model layer, the model of the World
Model of modelling formalism (eg. UML)
Metamodel, the model of model
The model of the model of modelling formalism
Meta-metamodell, the model of metamodel

5. What if the data is a program / a model?
Eg. CASE tools, compilers metamodeling
Metamodels for:
UML
RDBMS
While (C subset)
Tools
for a fixed metamodel hard coding the metamodel (eg. UML modeling tools)
for transformation between fixed metamodels hard coding of both metamodels  hard coding of transformation rules (eg. C compiler)
Tools for variable metamodel loadable, configurable metamodels (eg. ECLIPSE)
Intelligent information migration loadable metamodels and transformation rules
HARD CODING of the META-METAMODEL
the actual metamodel is an instance of the META-METAMODEL

6. (Part of an inaccurate) UML metamodel

7. While metamodel
‘Composite’ GoF pattern

8. Meta-metamodel
Eg. the UML metamodel as an instance of meta2model above:
START NAME END MIN MAX Feature owner Classifiable 1 1 Classifiable feature Feature 1 * Classifiable participant AssociationEnd 0 * AssociationEnd type Classifiable 1 1 Association connection AssociationEnd 2 * AssociationEnd owner Association 1 1 Parameter owner Operation 1 1 Operation parameter Parameter 0 *

9. CASE framework for customizable metamodel
(Eclipse) Meta-metamodel Framework (EMF)
Meta-metamodel
Metamodel1
Metamodel2
Metamodel3

10. Eclipse Eclipse Metamodel Framework (EMF): for metamodell creation
