Patterns for the Model-Based Development of RIAs

Rich Internet Applications (RIAs) are highly interactive web applications that resemble desktop applications. Modeling RIAs hence requires techniques for web modeling enriched by model elements for powerful user interactions and client-server communications. Many existing approaches provide the required modeling features, but they are still failing short in designer-friendliness and effectiveness. We present a pattern approach for the model-based engineering of RIAs that (1) reduces design efforts maintaining expressiveness of the models, and (2) contributes to model-driven development of RIAs. Our RIA patterns can be easily embedded in existing web modeling methods, which is illustrated with the UML-based Web Engineering.
