Our goalMain Goal:

MDE-based methodology for adaptable User Interfaces

Solution:

1. Model-Driven Engineering (MDE) solution

2. Model Evolution (by considering UI as models)

3. Model Transformation & Trading services

Considerations:

4. Component-based user interfaces

5. COTS (commercial off-the-shelf) UI components

6. Simple interfaces made up of UI components

7. Web-based User Interfaces as supporting collaborative interaction

Conclusions

• Adaptation schema of component-based systems at runtime based on the context observation

• Architectural models in two levels of abstraction:– AbstractArchitecturalModel (AAM): component types– ConcreteArchitecturalModel (CAM): concrete

components

• Trading process to regenerate the concrete definition of the architecture from the abstract definition.

• Observer Models to monitor the context and trigger the adaptation process

Conclusions• Model Transformations to adapt the architectural models

– Abstract definition: AbstractModelTransformation– Concrete definition: ConcreteModelTransformation

• Case study: Adaptation of component-based user interfaces at runtime (Major contribution of this work)

Future work• Build a wide concrete component repository

• Update the SemanticTrader implementation with a heuristic

• Add traceability mechanisms

• Variability of architectural models

• Improve the performance of the approach and incorporate evaluation techniques
