The development of accessible Web software is complicated for several reasons. Though some of them are technological, the
majority are related with the need to compose different and, many times, unrelated design concerns which may be functional
as in the case of most of the specific application’s requirements, or non-functional such as Accessibilit...
ContextInheritance is the cornerstone of object-oriented development, supporting conceptual modeling, subtype polymorphism and software reuse. But inheritance can be used in subtle ways that make complex systems hard to understand and extend, due to the presence of implicit dependencies in the inheritance hierarchy.ObjectiveAlthough these dependenc...
Improving navigability in Web applications is essential for applications success. Our research aims to improve the user experience
by applying novel techniques such as concern-sensitive navigation. Concern-sensitive navigation allows enriching Web pages
with content related to the context in which they are accessed. In previous works, we showed how...
The state of the art in location models falls short to adapt to new requirements such as composition and integration of maps. Composing and integrating maps are typical operations we want to apply when we deal with ubiquitous computing applications because they evolve permanently (i.e. to add location information of new cities, buildings, means of...
Spatial concerns of Web Geographical Information Systems (Web-GIS) are inherently crosscutting and volatile: crosscutting because they affect multiple functionalities of Web-GIS systems, such as visualization of a route in a map, volatile because their status may change often (e.g., in a map, a route can be obstructed temporarily due to a car accid...
Sketching web applications with mockup tools is a common practice that improves the process of elicitation and validation
of requirements in web applications. However, mockups are used as a “quick and dirty” way of gathering requirements, thus
discarded before development. As a consequence, concepts captured in them are usually lost in the manual t...
Improving navigability in Web applications is a serious challenge for developers as this quality feature is essential for applications success. In this paper we present the concept of concern-sensitive navigation, a useful conceptual tool to improve navigation by profiting from the nature of application's concerns. Concern sensitive navigation allo...

Since the first context-aware applications were designed, context modelling has played a central role. During the last decade
many different approaches were proposed to model context, ranging from ad-hoc models to extensions to relational databases
or ontologies. In this paper we propose to take a step back and analyse those approaches using the se...
Web development has moved from simple static pages to complex web applications, some of them resembling desktop ones. In most of these applications the web browser acts as thin-client (or a view) of the model that sits on the server. Despite the technological evolution of the web, there is still no standard mechanism to send data or events from the...
Web-GIS applications evolve fast as new requirements emerge constantly. Some of these requirements, particularly those related with spatial behaviours, might crosscut previous core application requirements. Conventional modelling techniques, which ignore the effect of crosscutting concerns (such as tangling and scattered behaviours) affect negative...
Mobile (or Physical) Hypermedia combines the navigational style typical of Web applications with the functionality of location and context-aware software. Users explore digital and physical relationships while accessing to information about their actual location, e.g. the object in front of them. Similar to "conventional" Web applications one might...
Traditionally, the use of good techniques to improve software modularity, such as advanced separation of concerns, has no impact in the user experience, for example while navigating Web software. While the intent of these techniques is to simplify evolution and maintenance, navigation design quality is often seen as an unrelated concern. In this pa...

The development of intelligent environments involves many dif-ferent disciplines and skills, which makes unrealistic to think that a single re-search group or company can develop all the hardware and software required to build such an environment. If we want to effectively support Weiser's vi-sion, what is really needed is an integration platform w...
By nature, web applications involve a myriad of different concerns, which many times crosscut each other. The result is that these crosscutting concerns are scattered throughout different software artifacts provoking information tangling in those concerns. This paper presents an approach for using the problem domain language captured by LEL (Langua...
Aspects sometimes conflict between them in scenarios where they reify resource awareness concerns. These conflicts are the result of the scarcity of resources and the fact that, frequently, aspects are mutually oblivious. This kind of conflict can be solved by manag- ing aspects according to the context. Obliviousness can be retained and, at the sa...
