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

Third Period

• Accent: Additional requirements to the architectures – Adaptive– Collaborative

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

Technological Level

• Multi-tiered architectures• Agents• Meta-data• Ontologies

Implementation

• General environment– J2EE (EE 5)

• Ontologies– Protégé

• Agents– JADE

• Portals– Life Ray– Private implementation

Standards

• E-content– SCORM

• User modeling– CC/PP– IMS LIP

• Domain modeling (ontologies)– OWL

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
