  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?

  9. Workshop Schedule – Session 1

  10. Workshop Schedule – Session 2

  11. Workshop Schedule - Discussion Groups

  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)
