4. Compuware Corporation 4 What are Transformations ?

5. Compuware Corporation 5 Breakfast Classes UML expressed in CWM Breakfast Tables expressed in MOF UML expressed in CWM MOF expressed in Formal Languages and Specifications Lang. X Specification A expressed in

6. Compuware Corporation 6 A Specification is a well-formed Structure with Meaning Lang. X well-formed according structure

7. Compuware Corporation 7 Transformations Lang. Y Specification B Lang. X Specification A expressed in Transformation C Transformation Definition Z defined by

8. Compuware Corporation 8 Example CWM Breakfast Tables UML Breakfast Classes expressed in B.Transformation defined by O/R Transform. Definition

9. Compuware Corporation 9 Example XML Schema UML XML Schema MOF UML expressed in U.Transformation defined by XMI

10. Compuware Corporation 10 well-formed according Matching and Deriving Patterns Lang. Y Lang. X well-formed according Transformation Definition Z derived patterns matched patterns defined by transformation

11. Compuware Corporation 11 well-formed according What is a Transformation ? Lang. Y Lang. X well-formed according Transformation Definition Z derived patterns matched patterns ? defined by

12. Compuware Corporation 12 well-formed according well-formed according A Transformation is a well- form Inter-Specification Structure Lang. Y Lang. X well-formed according Transformation Definition Z transformation derived patterns matched patterns

13. Compuware Corporation 13 well-formed according well-formed according Matching and Deriving Patterns Lang. Y Lang. X well-formed according Transformation Definition Z derived patterns transformation matched patterns

14. Compuware Corporation 14 well-formed according well-formed according Derivation of Patterns implies both Creation and Deletion Lang. Y Lang. X well-formed according Transformation Definition Z transformation C

15. Compuware Corporation 15 well-formed according well-formed according Derivation of Patterns implies both Creation and Deletion Lang. Y Lang. X well-formed according Transformation Definition Z transformation C

16. Compuware Corporation 16 well-formed according well-formed according Derivation of Patterns implies both Creation and Deletion Lang. Y Lang. X well-formed according Transformation Definition Z transformation C

17. Compuware Corporation 17 well-formed according well-formed according Some Transformations are Bi-Directional Lang. Y Lang. X well-formed according Transformation Definition Z transformation C matched patterns derived patterns

18. Compuware Corporation 18 Lang. Y Spec. B expressed in Transformations and MOF Lang. X Spec. A expressed in Transformation C Transformation Definition Z defined by MOF expressed in XMOF expressed in

19. Compuware Corporation 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

20. Compuware Corporation 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

21. Compuware Corporation 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
