With the internet going mobile and the combination of composite, service-oriented and adaptive web technologies, a broad range of novel commercial and personal application scenarios evolves. Future applications will be composed by dynamically combining different services with associated user interface components. They will adapt to user and device specific contexts and distribute functionality and interaction elements across multiple devices, according to the requirements of changing usage situations and user preferences. End users partake in the development process by specifying, assembling, and adapting mash-up applications, which suit their specific needs and capabilities. Yet, existing mashup approaches as, for instance, proposed by the CRUISe project, require technical understanding impeding the development by domain experts without programming skills.

Amongst others, shortcomings of current approaches are:


The research project EDYRA aims at simplifying the development process of composite and ubiquitous Rich Internet Applications utilizing mashup paradigms and web services. Novel methods and tools are supposed to enable the participation of end users as well as domain experts in the development of composite and ubiquitous Rich Internet Applications without the need for detailed programming skills. Hence, they are empowered to build web applications ad hoc and based on existing software components according to their requirements.

Roles in the envisioned development process

Amongst others, this comprises the following research goals and foci:
