Content
• SEDILIa background• Architecture• Work packages• Management• Flexible, adaptable, collaborative architectures• Conclusion
SEDILIa Background
• Our group– Established about 10 years ago
• Research field– Internet-based software architectures– Prototype applications
• Three periods
First Period
• Accent: Flexible architectures and applications– 1998 – establishment of E-Commerce Laboratory
(ECL)– E-Commerce Applications
• EDI• EDIFACT
– Disadvantage – need of external experts
Second Period
• Accent: Change of the domain– Applications in the field of eLearning– ECL was been transformed into DeLC
• Distributed eLearning Center
– Not need of external experts
JCSE
• Since 20001 we have participated in JCSE project– Aim – creation teaching material in SE
• In parallel to the DeLC project
SEDILIa Design Goals
• Results generalization of the previous efforts• Effective work in both projects
– JCSE, DeLC• An application of DeLC architecture

Flexible, adaptable, collaborative architecture
• Different levels:– Functional (Logical) level– (Partly) Formalization level– Standardization level– Technological level – Implementation level – Access level
Functional Level
• Support of three obvious (external) models– Domain model– User model– Pedagogical model
Implementation
• General environment– J2EE (EE 5)
• Ontologies– Protégé
• Agents– JADE
• Portals– Life Ray– Private implementation
Access
• Mobile (separated project)– Mobile services – InfoStation architecture
• Fixed– Education Portals
Conclusion
• Three years project• Intermediate reporting
– After 1,5 year • Three level reviewing
– First level – OK– Second level – ? (October’08)– Third level - ? (November’08)
Open Problems
• Formalization (Pedagogical model)– UML– Goal-oriented Networks– ITL (Tempura)
• Integration of different technologies– Life Ray – SCORM engine– JADE
• Acceptance
