4. Compuware Corporation 4 Introduction to the MDA Reference Model

5. Compuware Corporation 5 What is the the MDA Reference Model l A definition of the very basic concepts in MDA and their relations l A class model –defined using only common modeling constructs that are shared by UML and MOF l All MDA examples are instances of the MDA reference model –where the MDA examples can include all meta levels, all modeling languages and all technologies

6. Compuware Corporation 6 What is it good for ? l Captures existing MDA knowledge l Provides a basis for common understanding l Is a reference model to compare different MDA flavors / approaches l Exposes errors in what is being defined about MDA l Exposes deficiencies in what is being defined about MDA

7. Compuware Corporation 7 Plans for usages in the future l The current version is a draft draft in progress l It will be a fundamental part of a new version of the MDA Reference Guide l The AB will hopefully use it as a part of a new version of the OMA

8. Compuware Corporation 8 Requirements and Design rules l Vendor and MDA flavor neutral l UML oriented, profiling, mark-ups, MOF oriented, family of languages, Executable UML, … l Not a classification scheme of the different levels of abstraction, nor the different purposes of modeling languages l Precise yet not more formal then understandable l Layered: based on a kernel that is extended to more complex concepts l Rigid appreciation of the semantics of the used class model constructs of MOF and UML

9. Compuware Corporation 9 Who are creating it? l The ORMSC is mandated by the AB to develop a draft MDA Reference Model l Within the ORMSC a colorful palate of different MDA vendors are active l We develop one MDA Reference Model that does not exclude any MDA flavor l We are having a lot of fun !
