3. CAS-TIL Today’s Problem Individual End Users has little control over Web Interaction Programmers are in charge Web user interface and interaction flows are controlled by software programs deployed on the server These server side software programs are designed and implemented by software programmers Individual end user has no or very limited control over web interface nor interaction

4. CAS-TIL Today’s Problem What you see is what you get

5. CAS-TIL Related Work Server Side Approach –User Categorization: Profile: user characteristics (e.g. roles, organization etc.) Behavior (e.g. Page-Ranking) References: A. Datta et al, M. Vazirgiannis, M. Eirinaki –Portal User customized content E.g. iGoogle Major Limitations: –Small degree of customization –Not on an individual level

6. CAS-TIL Related Work Client Side Approach –Customized rendered web pages with browser extension GreaseMonkey Chickenfeet –Web Clipping Major Limitations: –Customization on rendered content that bears no correspondence to units of functionality from the server side

7. CAS-TIL mySOA: It’s All About “ME” Individual user: chooses from units of functionalities let the corresponding units of interaction artifacts and Flows be computed Result: individualized web interaction experience

8. CAS-TIL An SOA Enabled Alternative Leverage the SOA model of a “Service” as units of measure for server side functionality Build an abstract visualization finite state machine as the general model for web interaction with services Individual end user controls selection of units of server side functionalities using service interfaces as units of measure Corresponding individualized web interaction artifacts & flows are computed and generated by the client side plug-in This results in a truly individualized web interaction artifacts & flow that does not contain unwanted server side functionalities

9. CAS-TIL The Model of a Generic Service

10. CAS-TIL Mapping of the Generic Service Model to Create an Abstract Visualization Model

14. CAS-TIL Service based Finite State Machine

15. CAS-TIL It’s all about me – mySOA and ‘Me’ Object

17. CAS-TIL Summary SOA model of a “Service” as units of measure for server side functionality Build an abstract visualization finite state machine as the general model for web interaction with services Individual end user controls selection of units of server side functionalities using service interfaces as units of measure Corresponding individualized web interaction artifacts & flows are computed and generated by the client side plug-in This results in a truly individualized web interaction artifacts & flow that does not contain unwanted server side functionalities
