GUIML, creating dynamic GUI objects using XML

Due to the worldwide expansion of interest in the web in the past few years, a new strategy for application development has appeared in the information technology world: web modeling. This strategy covers the whole process of developing web applications and places emphasis on designing user interfaces, as well. Web modeling uses XML as description language which is suitable for defining markup languages. In business application XML needs a document object model (DOM) for accessing and managing data. Nowadays, the majority of applications interact with the user with the help of graphics user interfaces (GUIs). Such an interface is a composition of windows, buttons, listboxes, textfields, etc. This composition is static, which may be suitable for a number of applications but is not the best for data-intensive applications since they may need to alter GUI at runtime depending on data change over time. XUL is one way for doing that, and another one is DIGBE. We propose a new, XML-based solution: graphics user interface markup language (GUIML) is a platform and programming language neutral way of describing user interfaces using DOM for accessing UI definition. A GUIML document contains the definition of a user interface.

A system model and applications for intelligent campuses

Nowadays, when Future Internet and Internet of Things (IoT) research is an integral part of the rise of computing, we need to react to new challenges. According to prognoses of Gartner and ABI Research, by 2020 there will be nearly 30 billion devices connected to the Internet of Things wirelessly. Furthermore, a new computing concept has appeared which had a vision where computing is made to appear everywhere and anywhere. These technological advancements that have occurred during the past decade in various domains, including sensors, wireless communications, location positioning technologies, and the web, allow the efficient collection and processing of a wide range of data. These ideas are applied at our University Campus where we established an extensible data management architecture, on the top of which value-added services are provided for various people living or working on the Campus. Both the architecture and a couple of applications that make use of it will be discussed.
