CompuwareCorporation 19

• A transformation is a inter-specification structure with automated matching and deriving of patterns

• Creations, deletions and changes of elements are implied by the pattern constraints in the transformation definition

• Some transformations are bi-directional• Transformations transform instances of

models defined with MOF

Transformations Conclusions

CompuwareCorporation 20

Important Requirements for a Transformation Language

• Leverages current Model languages like MOF and OCL

• Defines transformations in a structural (non imperative) fashion

• Defines Transformations in an executable way

• Does NOT defines anything about the ‘how’ and the ‘when’ of the execution process

• Is user (writer & reader) friendly

CompuwareCorporation 21

XMOF• Compuware’s and SUN’s solution to the MOF 2.0

Q/V/T RFP

• Fulfills all the requirements as mentioned in this presentation and much more

• Is based on and reuses MOF / UML-infrastructure and OCL

• Models executable transformations

• Is a lean and mean extension to class modeling

• Is implemented and working

• Is very beautiful
