4. Last Workshop at UML 2004 (1) Reasons for Aspect-Oriented Modeling: Express crosscutting structures and behavior at a higher level of abstraction than aspect- oriented code Also:  Manage requirements  Enables modeling of business rules  Facilitates model evolution and maintenance  Helps to resolve conflicts in software models  Allows to express reusable functionality

5. Last Workshop at UML 2004 (2) Aspect-Orientation and UML  Are existing UML model elements capable of expression AO concepts?  We looked at classes / components / fragments / templates / packages Similar  Aspects are first-class entities  Instantiable classifiers  Encapsulate structural and behavioral properties Different  Provide introspection / intercession capabilities  Can define extrinsic properties of other elements  Break encapsulation of other elements

6. Last Workshop at UML 2004 (3) Aspect-Oriented Modeling and Terminology  Some thought that it would be beneficial to define an aspect- oriented vocabulary  "aspect“ Something now modular that otherwise crosscuts (vs. "concern", "view")  "join point“ Those points at which models can be woven together (too AspectJ)  "weaving“ (vs. merging, composition)  Final conclusion: too early Aspect-Oriented Modeling and the Software Development Process  Aspects differ depending on the development stage you're in  Aspects appear (and disappear!) at different development stages

7. Last Workshop at UML 2004 (4) Aspect-Oriented Modeling and Weaving  Weaving at model level more powerful than code weaving  Parallels to model transformation (MDA) -> horizontal transformation  When should weaving happen?  Symmetric vs. asymmetric AOM Questions for future workshop:  What are the reasons for using AOM at each software development phase?  What lessons can be learnt from other areas? OO, model composition and transformation, reflection?  How can we depict aspect-oriented introspection and intercession capabilities?

8. Let’s Introduce Ourselves Your name and affiliation Research interests Briefly  Any position you would like to state  Your goals in attending this workshop  Questions to be discussed  Where (with respect to the software development phases) do you want to use AOM?

11. Workshop Schedule - Discussion Groups 2:00pm-3:30pm Discussion Session I 3:30pm-4:00pm Break 4:00pm-5:00pm Discussion Session 2 5:00pm-5:45pm Working Group Summaries 5:45pm-6:00pm Group Photos

12. Breakout Discussion Groups For 3.5 hours, 3 groups discuss focused issues related to the workshop and report back to all participants The size of each group should be similar To reach consensus on the discussion topic areas:  Each workshop participant will suggest several issues to be discussed and write them on post-it notes “Is model weaving just a notational convention, or is tool support essential?” “Is a UML profile sufficient for modeling aspects, or is something additional needed?”  Related issues will be grouped together Each group should have a scribe and presenter (perhaps the same person) Try to stay focused and don’t get sidetracked on peripheral discussions (e.g., spending an hour defining the meaning of a specific word)
