One of the main characteristics of most Web applications is their high dynamism. Once implemented and deployed for the first time, new functionalities are added to meet new or changed requirements. Some of these functionalities may appear on the Web in response to an unexpected event, or phenomena (such as a natural calamity) after which they are removed. Some others are activated periodically, to coincide with a particular date, or period of the year (such as, return to school, Christmas holidays, etc.). Implementing such volatile functionalities usually impacts on a number of aspects of a Web application, including content, navigation, presentation, business processes, and user operations. Their cyclic activation/deactivation, which requires repetitive changes in the application code, may be the cause of waste of effort and application quality deterioration, up to incorrect functioning.In this paper, we present an approach to decouple the design and implementation of volatile functionalities from that of stable ones, i.e. the core functionalities of the application. The approach is instantiated in the context of the Object-Oriented Hypermedia Design Method (OOHDM), but its principles and related techniques are generally applicable to any other Web engineering method. We show how our approach enables the deployment and removal of these functionalities in a cost-effective and safe way and at runtime, thus providing business agility. A framework to classify volatile functionalities and a number of examples are also reported.

“…More recently, Hera and AMACONT have been extended with support for a combination of rule-based and aspect-oriented approaches [5,31] to enable the specification of multiple high-level design concerns. To this end, HyperAdapt [30] is ongoing work that currently investigates how to detect aspect interactions, conflict resolution and controlled linking of web adaptation aspects since this can become a major concern in complex applications based on this model [31]. In XCML, we instead build on a best-match approach that does not require the full specification of rules and conditions for the controlled linking between them.…”

XCML: providing context-aware language extensions for the specification of multi-device web applications

et al. 2012

There is a vast body of research dealing with the development of contextaware web applications that can adapt to different user, platform and device contexts. However, the range and growing diversity of new devices poses two significant problems to existing approaches. First, many techniques require a number of additional design processes and modelling steps before applications can be adapted. Second, the new generation of platforms and technologies underlying these devices as well as upcoming web standards HTML5 and CSS3 have partly changed the way in which web applications are implemented nowadays and often limit the way in which they can be adapted. In this paper, we present XCML as one example of a domain-specific language that tightly integrates context-aware concepts and adaptivity mechanisms to support developers in the specification and implementation of multi-channel web applications. In contrast to most existing approaches, the objective is to use a more lightweight approach to adaptation that can dynamically evolve and support new requirements as they emerge. Our solution builds on versioning principles in combination with a context matching process based on a declaration of contextdependent variants of content, navigation and presentation in terms of context expressions at different levels of granularity that are specific to the application. To support this, a formally defined context algebra is used to parse and resolve the

“…In general, when a context-aware page is requested, the adaptation operations are executed in order to adapt the content, navigation and presentation according to the client context. For the specification of adaptation operations, both rule-based approaches [6] following the Event-Condition-Action paradigm and aspect-oriented techniques [7] that promote the use of aspects to achieve a systematic separation of general system functionality and context-aware adaptation are popular.…”

There is a vast body of research dealing with the development of context-aware web applications that can adapt to different screen and user contexts. However, the range and growing diversity of devices used for web access makes it increasingly difficult for developers to provide a design and layout that adapts well to every client. To address this, we propose a crowdsourcing approach that allows developers to define a default web interface suitable for many devices and enables the crowd, i.e. other developers or even non-technical end-users, to adapt it to particular use contexts. We present an architecture for creating and sharing adaptations as well as suggesting and applying these in matching contexts. In addition, we discuss the underlying crowdsourcing principles and present a set of visual tools that facilitate the adaptation process.
