SCOPE OF THE WORK self-adapatable

Main Goal:

An MDE-based methodology for evolutive (adaptable) User Interfaces

Solution:

1. Model-Driven Engineering (MDE) solution.2. Model Evolution (by considering UI as models).3. Model transformation & Trading services.

Considerations:

1. Component-based user interfaces.2. COTS (commercial off-the-shelf) UI components.3. WIMP simple interfaces (Windows, Icons, Menus and Pointers).4. Web-based User Interfaces as supporting of WCIS (at runtime).

Architectural Metamodel

Architectural Modeli

1. Structural metamodel: composition dependencies between components through connection ports (i.e., provided and required interfaces).

2. Visual metamodel: components behaviour from a visual point of view (open, close, show, hide components, etc.) by means of a state machine.

3. Interaction metamodel: models the user-interaction behaviour, and describes the structure of interaction tasks that users may complete in the system.

“A choreography describes the protocol, or the sequence in which the tasks must be executed.”

Activity-diagram

“To facilitate the modelling, concepts have been collected in an ‘enumeration-class’ in the MM.”

Analyzes land areas in order to classify types of soil, affected area, etc.

Carries out an economic study from that information provided by the GIS expert.

Wishes to carry out a particular assessment of a natural disaster.
