3. WP2: Design principles; 2 nd AtGentive GM 21-22 May 2006, Oxford, UK The “Wish list” The “have to” and “nice to have”

4. WP2: Design principles; 2nd AtGentive GM 21-22 May 2006, Oxford, UK What we want Modularity, flexibility, simplicity. We want to focus our attention on improving the support for attention, not on solving technical problems. Possibility to reuse the work into individual applications (all the partners –and not only the partners involved in the platforms- should be able to take advantage of the output after the end of the project) Reduce the dependence between the partners (we have different agenda, priorities, styles, …).

5. WP2: Design principles; 2nd AtGentive GM 21-22 May 2006, Oxford, UK What we want (2) We want to work on things that make sense to us personally, and that we believe are useful. We would like to be the users of the tools and approaches that we develop. We want to design innovative things that have high added value. We want (and we need) that our deliverables are accepted by the EC

6. WP2: Design principles; 2 nd AtGentive GM 21-22 May 2006, Oxford, UK The flexible architecture The Web 2.0 principles Adopting web 2.0.

7. WP2: Design principles; 2nd AtGentive GM 21-22 May 2006, Oxford, UK The Web 2.0 principles: Principles Rich user experience; User participation; trust the users (Wikipedia); radical decentralisation (blog); emergence; more people use them the it is useful; fun to use; attitude; culture (community, versus process oriented, corporate and bureaucratic); navigation & serendipity. Approaches. Small pieces loosely joined; Mashup (combination); perpetual beta; granular addressability of content; tagging (not taxonomy. Folksonomies are not planned in advance); ideas originates from the “leisure Internet”.

9. WP2: Design principles; 2nd AtGentive GM 21-22 May 2006, Oxford, UK Web 2.0: The technical aspects The technicality of Web 2.0. A Different architecture. More distributed, loosely coupled, bottom-up, accessing external components. New technical mechanisms (web services, plugins, Ajax) and approaches (trackback, …) Rich client (Dhtml/Ajax, flash, …)

10. WP2: Design principles; 2nd AtGentive GM 21-22 May 2006, Oxford, UK The Adoption / adaptation to Atgentive: Components. Components are independent, simple, and have a very clear interface (web services, rich-client / server) Open Application / platform. Net API, plugin mechanisms. Open to external services. Instant messaging (Skype?, MSN), Tagging (Del.icio.us, Flickr), bloging, maps eXtreme Programming principles. Bottom-up, user centred, continuous improvement

11. WP2: Design principles; 2nd AtGentive GM 21-22 May 2006, Oxford, UK Web 2.0: The issues The issues related to Adopting Web 2.0. Need to open the architecture. Additional layer. Services exposed via a clear Interface (API, plugins). This interface exists for both the applications & platforms, and the components. What should be this interface? Can we express everything (complex things?). More distributed architecture. We can not really assume what it will be used for. Feeling of lost of control. More complex clients (Dhtml/Ajax, flash, …) Bottom-up / user-centred / incremental – continuous improvement (release often). Perpetual Beta.

12. WP2: Design principles; 2 nd AtGentive GM 21-22 May 2006, Oxford, UK Adoption / adaptation to AtGentive What is web 2.0 for us? How can we adopt web 2.0 principles

13. WP2: Design principles; 2nd AtGentive GM 21-22 May 2006, Oxford, UK The Adoption / adaptation to Argentive: Open Application / platform. The different platforms (ICDT, Ontdeknet, others?) should be opened (API / web services, plugin mechanisms). Ideas introduced by Claudia. We have to find some way to easily combine/glue the components (mashup). Note: Probably some commonalities, but most probably this work will be platform specific. External Components. External components will have to be selected and wrapped. Examples: Instant messaging (Skype?, MSN), Tagging (Del.icio.us, Flickr), blogging, etc.. Work: Some rich client interfaces will have to be created. Specific AtGentive Components. Difference specific AtGentive components will have to be created. Work: Creation of small server components (exposed via web services, or incorporable into plugins) + Rich client part.

14. WP2: Design principles; 2nd AtGentive GM 21-22 May 2006, Oxford, UK The artificial Characters ? The character should be considered as a rich client A server component for piloting this client will probably have to be designed. (suggestion: this server will be piloted via a high level API accessed via simple web services?)

15. WP2: Design principles; 2 nd AtGentive GM 21-22 May 2006, Oxford, UK How to proceed & conclusion

16. WP2: Design principles; 2nd AtGentive GM 21-22 May 2006, Oxford, UK How to proceed: Identification of the components. Specification of the functional specification according to a user centred perspective (Not a detailled technical description !). Alignment of these components to the Conceptual framework. Definition of the technical framework. Clarification of the different mechanisms and approaches to be used. Plugin, API, etc. Definition of a common API. (not too detailed, with the objective is to sketch the principles, and be ready for easy later additions) Architectural definition of the AtGentive Components. Definition of the server part and of the Rich client part.

17. WP2: Design principles; 2nd AtGentive GM 21-22 May 2006, Oxford, UK Conclusion: Key Challenges:  Alignment with the conceptual framework, and guidance of this framwork  Generate something useful, innovative and of high added value
