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 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
