In this Web 2.0 era, the browsers perform ever-richer graphical interfaces. Today, virtually every type of application can benefit from the ubiquity of Web browsers without compromising the user experience. Under the Model-Driven Development paradigm, models represent more than abstraction and documentation tools; they can also perform as powerful specification languages. When transformation rules are applied to these models, this can automate the repetitive task of generating infrastructure code. This work proposes an abstract RIA interface description language and a whole software environment that can make it possible to the application designer to automatically generate an executable interface from an abstract description. Being the Semantic Hypermedia Design Method (SHDM) development environment, the HyperDE framework became the target platform for the RIA interface code generation. Our solution also introduces a message queue-based protocol as a way to implement asynchronous communication between Model and View. It will make it possible to update the interface with the partial results of a request processing and, therefore, improve the user experience, enhancing what Ajax technology has accomplished so far.
